Trading Options: Understanding Assignment

Financial chart on LCD display stock photo

The options market can seem to have a language of its own. To the average investor, there are likely a number of unfamiliar terms, but for an individual with a short options position—someone who has sold call or put options—there is perhaps no term more important than " assignment "—the fulfilling of the requirements of an options contract.

Options trading carries risk and requires specific approval from an investor's brokerage firm. For information about the inherent risks and characteristics of the options market, refer to the Characteristics and Risks of Standardized Options also known as the Options Disclosure Document (ODD).

When someone buys options to open a new position ("Buy to Open"), they are buying a right —either the right to buy the underlying security at a specified price (the strike price) in the case of a call option, or the right to sell the underlying security in the case of a put option.

On the flip side, when an individual sells, or writes, an option to open a new position ("Sell to Open"), they are accepting an obligation —either an obligation to sell the underlying security at the strike price in the case of a call option or the obligation to buy that security in the case of a put option. When an individual sells options to open a new position, they are said to be "short" those options. The seller does this in exchange for receiving the option's premium from the buyer.

American-style options allow the buyer of a contract to exercise at any time during the life of the contract, whereas European-style options can be exercised only during a specified period just prior to expiration. For an investor selling American-style options, one of the risks is that the investor may be called upon at any time during the contract's term to fulfill its obligations. That is, as long as a short options position remains open, the seller may be subject to "assignment" on any day equity markets are open.

What is assignment?

An option assignment represents the seller's obligation to fulfill the terms of the contract by either selling or buying the underlying security at the exercise price. This obligation is triggered when the buyer of an option contract exercises their right to buy or sell the underlying security.

To ensure fairness in the distribution of American-style and European-style option assignments, the Options Clearing Corporation (OCC), which is the options industry clearing house, has an established process to randomly assign exercise notices to firms with an account that has a short option position. Once a firm receives an assignment, it then assigns this notice to one of its customers who has a short option contract of the same series. This short option contract is selected from a pool of such customers, either at random or by some other procedure specific to the brokerage firm.

How does an investor know if an option position will be assigned?

While an option seller will always have some level of uncertainty, being assigned may be a somewhat predictable event. Only about 7% of options positions are typically exercised, but that does not imply that investors can expect to be assigned on only 7% of their short positions. Investors may have some, all or none of their short positions assigned.

And while the majority of American-style options exercises (and assignments) happen on or near the contract's expiration, a long options holder can exercise their right at any time, even if the underlying security is halted for trading. Someone may exercise their options early based upon a significant price movement in the underlying security or if shares become difficult to borrow as the result of a pending corporate action such as a buyout or takeover.

Note: European-style options can only be exercised during a specified period just prior to expiration. In U.S. markets, the majority of options on commodity and index futures are European-style, while options on stocks and exchange-traded funds (ETF) are American-style. So, while SPDR S&P 500, or SPY options, which are options tied to an ETF that tracks the S&P 500, are American-style options, S&P 500 Index options, or SPX options, which are tied to S&P 500 futures contracts, are European-style options.

What happens after an option is assigned?

An investor who is assigned on a short option position is required to meet the terms of the written option contract upon receiving notification of the assignment. In the case of a short equity call, the seller of the option must deliver stock at the strike price and in return receives cash. An investor who doesn't already own the shares will need to acquire and deliver shares in return for cash in the amount of the strike price, multiplied by 100, since each contract represents 100 shares. In the case of a short equity put, the seller of the option is required to purchase the stock at the strike price.

How might an investor's account balance fluctuate after opening a short options position?

It is normal to see an account balance fluctuate after opening a short option position. Investors who have questions or concerns or who do not understand reported trade balances and assets valuations should contact their brokerage firm immediately for an explanation. Please keep in mind that short option positions can incur substantial risk in certain situations.

For example, say XYZ stock is trading at $40 and an investor sells 10 contracts for XYZ July 50 calls at $1.00, collecting a premium of $1,000, since each contract represents 100 shares ($1.00 premium x 10 contracts x 100 shares). Consider what happens if XYZ stock increases to $60, the call is exercised by the option holder and the investor is assigned. Should the investor not own the stock, they must now acquire and deliver 1,000 shares of XYZ at a price of $50 per share. Given the current stock price of $60, the investor's short stock position would result in an unrealized loss of $9,000 (a $10,000 loss from delivering shares $10 below current stock price minus the $1,000 premium collected earlier).

Note: Even if the investor's short call position had not been assigned, the investor's account balance in this example would still be negatively affected—at least until the options expire if they are not exercised. The investor's account position would be updated to reflect the investor's unrealized loss—what they could lose if an option is exercised (and they are assigned) at the current market price. This update does not represent an actual loss (or gain) until the option is actually exercised and the investor is assigned.

What happens if an investor opened a multi-leg strategy, but one leg is assigned?

American-style option holders have the right to exercise their options position prior to expiration regardless of whether the options are in-, at- or out-of-the-money. Investors can be assigned if any market participant holding calls or puts of the same series submits an exercise notice to their brokerage firm. When one leg is assigned, subsequent action may be required, which could include closing or adjusting the remaining position to avoid potential capital or margin implications resulting from the assignment. These actions may not be attractive and may result in a loss or a less-than-ideal gain.

If an investor's short option is assigned, the investor will be required to perform in accordance with their obligation to purchase or deliver the underlying security, regardless of the overall risk of their position when taking into account other options that may be owned as part of the overall multi-leg strategy. If the investor owns an option that serves to limit the risk of the overall spread position, it is up to the investor to exercise that option or to take other action to limit risk.

Below are a couple of examples that underscore how important it is for every investor to understand the risks associated with potential assignment during market hours and potentially adverse price movements in afterhours trading.

Example #1: An investor is short March 50 XYZ puts and long March 55 XYZ puts. At the close of business on March expiration, XYZ is priced at $56 per share, and both puts are out of the money, which means they have no intrinsic value. However, due to an unexpected news announcement shortly after the closing bell, the price of XYZ drops to $40 in after-hours trading. This could result in an assignment of the short March 50 puts, requiring the investor to purchase shares of XYZ at $50 per share. The investor would have needed to exercise the long March 55 puts in order to realize the gain on the initial multi-leg position. If the investor did not exercise the March 55 puts, those puts may expire and the investor may be exposed to the loss on the XYZ purchase at $50, a $10 per share loss with XYZ now trading at $40 per share, without receiving the benefit of selling XYZ at $55.

Example #2: An investor is short March 50 XYZ puts and long April 50 XYZ puts. At the close of business on March expiration, XYZ is priced at $45 per share, and the investor is assigned XYZ stock at $50. The investor will now own shares of XYZ at $50, along with the April 50 XYZ puts, which may be exercised at the investor's discretion. If the investor chooses not to exercise the April 50 puts, they will be required to pay for the shares that were assigned to them on the short March 50 XYZ puts until the April 50 puts are exercised or shares are otherwise disposed of.

Note: In either example, the short put position may be assigned prior to expiration at the discretion of the option holder. Investors can check with their brokerage firm regarding their option exercise procedures and cut-off times.

What Is an Option Assignment?

Definition and Examples of Assignment

How does assignment work, what it means for individual investors.

Morsa Images / Getty Images

An option assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price. Let’s explain what that means in more detail.

Key Takeaways

An assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price.
If you sell an option and get assigned, you have to fulfill the transaction outlined in the option.
You can only get assigned if you sell options, not if you buy them.
Assignment is relatively rare, with only 7% of options ultimately getting assigned.

An assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price. Let’s explain what that means in more detail.

When you sell an option to someone, you’re selling them the right to make you engage in a future transaction. For example, if you sell someone a put option , you’re promising to buy a stock at a set price any time between when the transaction happens and the expiration date of the option.

If the holder of the option doesn’t do anything with the option by the expiration date, the option expires. However, if they decide that they want to go through with the transaction, they will exercise the option.

If the holder of an option chooses to exercise it, the seller will receive a notification, called an assignment, letting them know that the option holder is exercising their right to complete the transaction. The seller is legally obligated to fulfill the terms of the options contract.

For example, if you sell a call option on XYZ with a strike price of $40 and the buyer chooses to exercise the option, you’ll be assigned the obligation to fulfill that contract. You’ll have to buy 100 shares of XYZ at whatever the market price is, or take the shares from your own portfolio and sell them to the option holder for $40 each.

Options traders only have to worry about assignment if they sell options contracts. Those who buy options don’t have to worry about assignment because in this case, they have the power to exercise a contract, or choose not to.

The options market is huge, in that options are traded on large exchanges and you likely do not know who you’re buying contracts from or selling them to. It’s not like you sell an option to someone you know and they send you an email if they choose to exercise the contract, rather it is an organized process.

In the U.S., the Options Clearing Corporation (OCC), which is considered the options industry clearinghouse, helps to facilitate the exchange of options contracts. It guarantees a fair process of option assignments, ensuring that the obligations in the contract are fulfilled.

When an investor chooses to exercise a contract, the OCC randomly assigns the obligation to someone who sold the option being exercised. For example, if 100 people sold XYZ calls with a strike of $40, and one of those options gets exercised, the OCC will randomly assign that obligation to one of the 100 sellers.

In general, assignments are uncommon. About 7% of options get exercised, with the remaining 93% expiring. Assignment also tends to grow more common as the expiration date nears.

If you are assigned the obligation to fulfill an options contract you sold, it means you have to accept the related loss and fulfill the contract. Usually, your broker will handle the transaction on your behalf automatically.

If you’re an individual investor, you only have to worry about assignment if you’re involved in selling options. Even then, assignments aren't incredibly common. Less than 7% of options get assigned and they tend to get assigned as the option’s expiration date gets closer.

Having an option assigned does mean that you are forced to lock in a loss on an option, which can hurt. However, if you’re truly worried about assignment, you can plan to close your position at some point before the expiration date or use options strategies that don’t involve selling options that could get exercised.

It’s that unassuming piece in the machinery that can, without warning, change the entire game – often carrying notable financial repercussions. In a domain where every move has implications, truly grasping option assignment is foundational, ensuring not just survival but genuine success.

Join us in this comprehensive exploration of option assignment, arming traders of all experience levels with the knowledge to sail these intricate seas with assuredness and accuracy.

What you’ll learn

What is Options Assignment?

How options assignment works, identifying option assignment , examples of option assignment, managing and mitigating assignment risks, what option assignment means for individual traders.

Conclusion

Dive into the realm of options trading and you’ll find a tapestry of processes and potential. “Options assignment” is one pivotal cog in this intricate machine. To a newcomer, this term might seem a tad daunting. But a step-by-step walk-through can demystify its core.

In its simplest form, options assignment means carrying out the rights specified in an option contract. Holding an option allows a trader the choice to buy or sell a particular asset, but there’s no compulsion. The moment they opt to use this right, that’s when options assignment kicks in.

Think of it this way: You’ve got a ticket (option) to a show (buy or sell an asset). You decide if and when to attend. When you make the move, that transition is the options assignment.

There are two main types of option assignments:

Call Option Assignment : Triggered when a call option holder exercises their right. The seller of the option then steps into the spotlight, bound to sell the asset at the agreed-upon price.
Put Option Assignment : Conversely, if a put option holder steps forward, the seller of the put takes the stage. Their role? To buy the asset at the specified rate.

To truly grasp options assignment, one must understand the dance between rights and obligations in options trading.

When a trader buys an option, they’re essentially reserving a right, a possible move. On the other hand, selling an option translates to accepting a duty if the option’s holder chooses to play their card.

Rights with Call Options: Buying a call option grants you a special privilege. You can procure the underlying asset at a set price before the option expires. If you choose to exercise this right, the one who sold you the call gets assigned. Their task? Handing over the asset at that set price.

Obligations with Put Options: Securing a put option empowers you to sell the underlying at a pre-decided rate. Should you exercise this, the put’s seller steps up, committed to buying the asset at the given rate.

Several factors steer the course of options assignment, including intrinsic value, looming expiration dates, and current market vibes. To stay ahead of these influences, many traders utilize option trade alerts for timely insights. And remember, while many options might find buyers, not all see execution. Hence, not every seller will get assigned. For traders, understanding this rhythm is vital, shaping many strategies in options trading.

In the multifaceted world of options trading, discerning option assignment straddles the line between art and science. While no technique guarantees surefire results, several pointers and signals can wave a flag, hinting at an impending assignment.

In-the-Money Options : A robust sign of a looming assignment is the option’s stance relative to its strike price. “In-the-money” refers to an option’s moneyness , and plays a pivotal role in the behavior of option holders. Deeply in-the-money (ITM) options amplify the odds of assignment. An ITM call option, where the market price of the asset towers above the strike price, encourages the holder to exercise and swiftly offload the asset on the market. Conversely, an ITM put option, where the market price trails significantly behind the strike price, incentivizes the holder to scoop up the asset in the market and then exercise the option to vend it at the loftier strike price.

Expiration’s Shadow: The ticking clock of an expiring option raises the assignment stakes, especially if it remains ITM. Many traders make their move just before the eleventh hour to capitalize on their gains.

Dividend Dates in Focus: Call options inching toward expiry ahead of a dividend date, especially if they’re ITM, stand at an elevated assignment crosshair. Option aficionados might play their call options to pocket the dividend, which they’d bag if they possess the core shares.

Extrinsic Value’s Decline : A diminishing time or extrinsic value of an option elevates its exercise odds. When intrinsic value dominates an option’s worth, a holder might be inclined to cash in on this value.

Volume & Open Interest Dynamics : A sudden surge in trading or a dip in open interest can be telltale signs. Understanding volume’s role is crucial as such fluctuations might hint at traders either hopping in or out, suggesting possible exercises and assignments.

Navigating the Post-Assignment Terrain

Grasping the ripple effects of option assignment is vital, highlighting the immediate responsibilities and potential paths for both the buyer and seller.

For the Option Seller:

Call Option Assignment : For a trader who’s sold a call option, assignment means they’re on the hook to hand over the underlying shares at the strike price. If they’re short on shares, a market purchase is in order—potentially at a loss if market prices overshoot the strike.
Put Option Assignment: Assignment on a peddled put option necessitates the trader to buy the shares at the strike price . If this price overshadows the market rate, losses loom.

For the Option Buyer:

Call Option Play : Exercising a call lets the buyer snap up shares at the strike price. They can either nestle with them or trade them off.
Put Option Play: Exercising a put gives the buyer the reins to sell their shares at the strike price. This play often pays off when the market rate is dwarfed by the strike, ensuring a tidy profit on the dispensed shares.

Post-assignment, all involved must be on their toes, knowing what triggers margin calls , especially if caught off-guard by the assignment. Tax implications may also hover, influenced by the trade’s nature and the tenure of the position.

Being savvy about these subtleties and gearing up for possible turns of events can drastically refine one’s journey through the options trading maze.

Call Option Assignment Scenario

Imagine an investor purchases an Nvidia ( NVDA ) call option at a strike price of $435, hoping that the price of the stock will ascend after finding out that they may be forced to move out of some countries . The option is set to expire in a month. Soon after, not only did NVDA rebound from the news, but they reported very strong quarterly earnings, propelling the stock to $455.

Spotting the favorable trend, the investor opts to wield their right to purchase the stock at the agreed strike price of $435, despite its $455 market value. This initiates the option assignment.

The other investor, having sold the option, must now part with their NVDA shares at $435 apiece. If they’re short on stocks, they’d have to fetch them at the going rate of $455 and let them go at a deficit. The first investor, however, stands at a crossroads: retain the shares in hopes of further gains or swiftly trade them at $455, reaping a neat sum.

Put Option Assignment Scenario

Let’s visualize an investor who speculates a dip in the share price of V.F. Corporation ( VFC ) after seeing news about an activist investor causing shares to jump almost 14% in a day . To hedge their bets, they secures a put option from another investor at a strike price of $18.50, set to lapse in a month.

Fast forward a week, let’s say VFC divulges lackluster quarterly figures, causing the stock to dive to $10. The first investor, seizing the moment, employs their put option, electing to sell their shares at the $18.50 strike price.

When the assignment bell tolls, the other investor finds himself bound to buy the shares from the first investor at the agreed $18.50, a rate that overshadows the current $10 market value. The first investor thus sidesteps the market slump, securing a favorable sale. The other investor, however, absorbs a loss, acquiring stocks at a premium to their market worth.

The realm of options trading is akin to navigating a dynamic river, demanding a sharp comprehension of the risks that lie beneath its surface. A predominant risk that traders often encounter is assignment risk. When one assumes the role of an option seller, they inherit the duty to honor the contract if the buyer opts to exercise. Grasping the gravity of this can make the difference, underscoring the necessity of adept risk management.

A savvy approach to temper assignment risk is by keeping a vigilant eye on the extrinsic value of options. Generally, options rich in extrinsic value tend to resist early assignment. This resistance emerges as the extrinsic value dwindles when the option dives deeper in-the-money, thereby tempting the holder to exercise.

Furthermore, economic currents, ranging from niche corporate updates to sweeping market tides, can be triggers for option assignments. Staying attuned to these economic ripples equips traders with the vision needed to either tweak or maintain their positions. For example, traders may opt to sidestep selling options that are deeply in-the-money, given their higher susceptibility to assignments due to their shrinking extrinsic value.

Incorporating spread tactics, like vertical spreads or iron condors, furnishes an added shield. These strategies can dampen the risk of assignment since one part of the spread frequently balances the risk of its counterpart. Should the specter of a short option assignment hover, traders might contemplate ‘rolling out’ their stance. This move entails repurchasing the short option and subsequently selling another, possibly at a varied strike rate or a more distant expiry.

Yet, despite these protective layers, it remains pivotal for traders to brace for possible assignments. Maintaining ample liquidity, be it in capital or necessary shares, can avert unfavorable scenarios like hasty liquidations or stiff margin charges. Engaging regularly with brokers can also shed light, occasionally offering a heads-up on looming assignments.

In conclusion, the bedrock of risk management in options trading is rooted in perpetual learning. As traders hone their craft, their adeptness at forecasting and navigating assignment risks sharpens.

In the intricate world of options trading, option assignments aren’t just nuanced details; they’re pivotal moments with deep-seated implications for individual traders and the health of their portfolios. Beyond the immediate financial aftermath, assignments can reshape trading plans, risk dynamics, and the overarching path of an investor’s journey.

At its core, option assignments can transform a trader’s asset landscape. Consider a trader who’s short on a call option. If they’re assigned, they might be compelled to supply the underlying stock. This can result in a rapid stock outflow from their portfolio or, if they don’t possess the stock, birth a short stock stance. On the flip side, a trader short on a put option who faces assignment may find themselves buying the stock at the strike price, thereby dipping into their cash reserves.

These immediate shifts can generate broader portfolio ripples. An unexpected gain or shedding of stocks can jostle a trader’s asset distribution, veering it off their envisioned path. If, for instance, a trader had charted a particular stock-to-cash distribution or a meticulous diversification blueprint, an option assignment might throw a spanner in the works.

Additionally, assignments can serve as a real-world litmus test for a trader’s risk-handling prowess . A surprise assignment might spark margin calls for those not sufficiently fortified with capital. It stands as a poignant nudge about the essence of ensuring liquidity and safeguarding against the unpredictable whims of the market.

Strategically speaking, recurrent assignments might signal it’s time for traders to recalibrate. Are the options they’re offloading too submerged in-the-money? Have they factored in pivotal market shifts that might heighten early exercise odds? Such reflective moments can pave the way for refining and elevating trading methods.

In the multifaceted world of options trading, option assignment stands out as both a potential boon and a challenge. Far from being a simple checkbox in the process, its ramifications can mold the contours of a trader’s portfolio and steer long-term tactics. The importance of comprehending and adeptly managing option assignment resonates, whether you’re dipping your toes into options for the first time or weaving through intricate trades with seasoned expertise.

Furthermore, mastering options trading is about integrating its myriad concepts into a cohesive playbook. Whether it’s differentiating trading strategies like the iron condor from the iron butterfly strategy or delving deep into the nuances of option assignments, each component enriches the narrative of a trader’s odyssey. As markets shift and new hurdles arise, a solid grasp of foundational principles remains an invaluable asset. In this perpetual dance of learning and evolution, may your trading maneuvers always be well-informed, proactive, and adept.

Understanding Options Assignment: FAQs

What factors influence the likelihood of an option being assigned.

Several factors come into play, including the option’s intrinsic value , the time remaining until expiration, and upcoming dividend announcements. Options that are deep in the money or nearing their expiration date are more likely to be assigned.

Are Some Option Styles More Prone to Assignment than Others?

Absolutely. When considering different option styles , it’s essential to note that American-style options can be exercised at any point before their expiration, which means they face a higher risk of early assignment. In contrast, European-style options can only be exercised at expiration.

How Do Current Market Trends Impact Assignment Risk?

Factors like market volatility, notable price shifts, and external economic happenings can amplify the chances of an option being assigned. For example, an option might be assigned before a company’s ex-dividend date if the expected dividend outweighs the weakening of theta decay .

Can Traders Reverse or Counter the Effects of an Option Assignment?

Once an option has been assigned, it’s set in stone. However, traders can maneuver within the market to balance out the implications of the assignment, such as procuring or selling the underlying asset.

Are There Any Fees Tied to Option Assignments?

Indeed, brokers usually impose a fee for both assignments and exercises. The specific fee can differ depending on the broker, making it essential for traders to understand their brokerage’s charging scheme.

What is Options Assignment & How to Avoid It

If you are learning about options, assignment might seem like a scary topic. In this article, you will learn why it really isn’t. I will break down the entire options assignment process step by step and show you when you might be assigned, how to minimize the risk of being assigned, and what to do if you are assigned.

Video Breakdown of Options Assignment

Check out the following video in which I explain everything you need to know about assignment:

What is Assignment?

To understand assignment, we must first remember what options allow you to do. So let’s start with a brief recap:

A call option gives its buyer the right to buy 100 shares of the underlying at the strike price
A put option gives its buyer the right to sell 100 shares of the underlying at the strike price

In other words, call options allow you to call away shares of the underlying from someone else, whereas a put option allows you to put shares in someone else’s account. Hence the name call and put option.

The assignment process is the selection of the other party of this transaction. So the person that has to buy from or sell to the option buyer that exercised their option.

Note that an option buyer has the right to exercise their option. It is not an obligation and therefore, a buyer of an option can never be assigned. Only option sellers can ever be get assigned since they agree to fulfill this obligation when they sell an option.

Let’s go through a specific example to clarify this:

The underlying security is stock ABC and it is trading at $100.
Peter decides to buy 1 put option with a strike price of 95 as a hedge for his long stock position in ABC
Kate sells this exact same option at the same time.

Over the next few weeks, ABC’s price goes down to $90 and Peter decides to exercise his put option. This means that he uses his right to sell 100 shares of ABC for $95 per share. Now Kate is assigned these 100 shares of ABC which means she is obligated to buy them for $95 per share.

Peter now has 100 fewer shares of ABC in his portfolio, whereas Kate has 100 more.

This process is analog for a call option with the only difference being that Kate would be short 100 shares and Peter would have 100 additional shares of ABC in his portfolio.

Hopefully, this example clarifies what assignment is.

Who Can Be Assigned?

To answer this question, we must first ask ourselves who exercises their option? To do this, let’s quickly look at the different ways that you can close a long option position:

Sell the option: Selling an option is probably the easiest way to close a long option position. Doing this will have no effect on the option seller.
Let the option expire: If the option is Out of The Money , it would expire worthless and there would be no consequence for the option seller. If, on the other hand, the option is In The Money by more than $0.01, it would typically be automatically exercised . This would start the options assignment process.
Exercise the option early: The last possibility would be to exercise the option before its expiration date. This, however, can only be done if the option is an American-style option. This would, once again, lead to an option assignment.

So as an option seller, you only have to worry about the last two possibilities in which the buyer’s option is exercised.

But before you worry too much, here is a quick fact about the distribution of these 3 alternatives:

Less than 10% of all options are exercised.

This means 90% of all options are either sold prior to the expiration date or expire worthless. So always remember this statistic before breaking your head over the risk of being assigned.

It is very easy to avoid the first case of being assigned. To avoid it, just close your short option positions before they expire (ITM). For the second case, however, things aren’t as straight forward.

Who Risks being Assigned Early?

Firstly, you have to be trading American-style options. European-style options can only be exercised on their expiration date. But most equity options are American-style anyway. So unless you are trading index options or other kinds of European-style options, this will be the case for you.

Secondly, you need to be an options seller. Option buyers can’t be assigned.

These two are necessary conditions for you to be assigned. Everyone who fulfills both of these conditions risks getting assigned early. The size of this risk, however, varies depending on your position. Here are a few things that can dramatically increase your assignment risk:

ITM: If your option is ITM, the chance of being assigned is much higher than if it isn’t. From the standpoint of an option buyer, it does not make sense to exercise an option that isn’t ITM because this would lead to a loss. Nevertheless, it is possible. The deeper ITM the option is, the higher the assignment risk becomes.
Dividends : Besides that, selling options on securities with upcoming dividends also increases your risk of assignment. More specifically, if the extrinsic value of an ITM call option is less than the amount of the dividend, option buyers can achieve a profit by exercising their option before the ex-dividend date.
Extrinsic Value: Otherwise, keep an eye on the extrinsic value of your option. If the option has extrinsic value left, it doesn’t make sense for the option buyer to exercise their option because they would achieve a higher profit if they just sold the option and then bought or sold shares of the underlying asset. Typically, the less time an option has left, the lower its extrinsic value becomes. Implied volatility is another factor that influences extrinsic value.
Puts vs Calls: This is more of an interesting side note than actual advice, but put options tend to get exercised more often than call options. This makes sense since put options give their buyer the right to sell the underlying asset and can, therefore, be a very useful hedge for long stock positions.

How can you Minimize Assignment Risk?

Since you now know what assignment is, and who risks being assigned, let’s shift our focus on how to minimize the assignment risk. Even though it isn’t possible to completely remove the risk of being assigned, there are things that you can do to dramatically decrease the chances of being assigned.

The first thing would be to avoid selling options on securities with upcoming dividend payments. Before putting on a position, simply check if the underlying security has any upcoming dividend payments. If so, look for a different trade.

If you ever are in the position that you are short an option and the ex-dividend of the underlying security is right around the corner, compare the size of the dividend to the extrinsic value of your option. If the extrinsic value is less than the dividend amount, you really should consider closing the position. Otherwise, the chances of being assigned are high. This is especially bad since being short during a dividend payment of a security will force you to pay the dividend.

Besides avoiding dividends, you should also close your option positions early. The less time an option has left, the lower its extrinsic value becomes and the more it makes sense for option buyers to exercise their options. Therefore, it is good practice to close your (ITM) short option positions at least one week before the expiration date.

The deeper an option is ITM, the higher the chances of assignment become. So the just-mentioned rule is even more important for deep ITM options.

If you don’t want to indefinitely close your position, it is also possible to roll it out to a later expiration cycle. This will give you more time and add extrinsic value to your position.

FAQs about Assignment

Last but not least, I want to answer some frequently asked questions about options exercise and assignment.

1. What happens if your account does not have enough buying power to cover the assigned position?

This is a common worry for beginning options traders. But don’t worry, if you don’t have enough capital to cover the new position, you will receive a margin call and usually, your broker will just automatically close the assigned shares immediately. This might lead to a minor assignment fee, but otherwise, it won’t significantly affect your account. Tatsyworks, for example, charges an assignment fee of only $5.

Check out my review of tastyworks

2. How does assignment affect your P&L?

When an option is exercised, the option holder gains the difference between the strike price and the price of the underlying asset. If the option is ITM, this is exactly the intrinsic value of the option. This means that the option holder loses the extrinsic value when he exercises his/her option. That’s also why it doesn’t make sense to exercise options with a lot of extrinsic value left.

This means that as soon as the option is exercised, it is only the intrinsic value that is relevant for the payoff. This is the same payoff as the option at its expiration date.

So as an options seller, your P&L isn’t negatively affected by an assignment. Either it stays the same or it becomes slightly better due to the extrinsic value being ignored.

As an example, if your option is ITM by $1, you will lose up to $100 per option or $1 per share that you are assigned. But this does not account for the extrinsic value that falls away with the exercise of the option. So this would be the same P&L as at expiration. Depending on how much premium you collected when selling the option, this might still be a profit or a minor loss.

With that being said, as soon as you are assigned, you will have some carrying risk. If you don’t or can’t close the position immediately, you will be exposed to the ongoing price fluctuations of that security. Sometimes, you might not be able to close the new position immediately because of trading halts, or because the market is closed.

If you weren’t planning on holding that security, it is a good idea to close the new position as soon as possible.

Option spreads such as vertical spreads, add protection to these price fluctuations since you can just exercise the long option to close the assigned share position at the strike price of the long option.

3. When an option holder exercises their option, how is the assignment partner chosen?

This is usually a random process. As soon as an option is exercised, the responsible brokerage firm sends a request to the Options Clearing Corporation (OCC). They send back the requested shares, whereafter they randomly choose another brokerage firm that currently has a client that is short the exercised option. Then the chosen broker has to decide which of their clients is assigned. This choice is, once again, random or a time-based priority system is used.

4. How does assignment work for index options?

As there aren’t any shares of indexes, you can’t directly be assigned any shares of the underlying asset. Therefore, index options are cash-settled. This means that instead of having to buy or sell shares of the underlying, you simply have to pay the difference between the strike price and the underlying trading price. This makes assignment easier and a lot less likely among index options.

Note that ETF options such as SPY options are not cash-settled. SPY is a normal security with openly traded shares, so exercise and assignment work just like they do among equity options.

I hope this article made you realize that assignment isn’t as bad as it might seem at first. It is just important to understand how the options assignment process works and what affects the likelihood of being assigned.

To recap, here’s what you should to do when you are assigned:

if you have enough capital in your account to cover the position, you could either treat the new position as a normal (stock) position and hold on to it or you could close it immediately. If you don’t have a clear trading plan for the new position, I recommend the latter.

If, on the other hand, you don’t have enough buying power, you will receive a margin call from your broker and the position should be closed automatically.

Assignment does not have any significant impact on your P&L, but it comes with some carrying risk. Options spreads can offer more protection against this than naked option positions.

To mitigate assignment risk, you should close option positions early, always keep an eye on the extrinsic value of your option positions, and avoid upcoming dividend securities.

And always remember, less than 10% of options are exercised, so assignment really doesn’t happen that often, especially not if you are actively trying to avoid it.

For the specifics of how assignment is handled, it is a good idea to contact your broker, as the procedures can vary from broker to broker.

22 Replies to “What is Options Assignment & How to Avoid It”

hi there well seems like finally there is one good honest place. seem like you are puting on the table the whole truth about bad positions. however my wuestion is when can one know where to put that line of limit. when do you recognise or understand that you are in a bad position? thanks and once again, a great site.

Well If you are trading a risk defined strategy the point would be at max loss and not too much time left until expiration. For undefined risk strategies however it can be very different. I would just say if you don’t have too much time until expiration and are far from making money you should use some common sense and admit that you are wrong.

What would happen in the event of a crash. Would brokers be assigning, options, cashing out these shares, and making others bankrupt. Well, I guessed I sort of answered my own question. Its not easy to understand, especially not knowing when this would come up. But seems like you hit the important aspects of the agreement.

Actually I wouldn’t imagine that too many people would want to exercise their options in case of a market ctash, because they probably wouldn’t want to hold stocks in this risky and volatile environment.

And to the part of the questions: making others bankrupt. This really depends on the situation. You can’t get assigned more stock than your option covers. This means as long as you trade with reasonable position sizing nothing too bad can happen. Otherwise I would recommend to trade with defined risk strategies so your maximum drawdown is capped.

Thanks for writing about assignment Louis. After reading the section how assignment works, I feel I am somewhat unclear about how assignment works when the exerciser exercises Put or Call option. In both cases, if the underlying is an index, is the settlement done through the margin account money? Would you be able to provide a little more detail of how exercising the option (Put vs Call) would work in case of an underlying stock vs Index.

Thank you very much in advance

Thanks for the question. Indexes can’t be traded in the same way as stocks can. That’s why index options are settled in cash. If your index option is assigned, you won’t have to buy or sell any shares of the underlying index at the strike price because there exist no shares of indexes. Instead, you have to pay the amount that your index option is ITM to the exerciser of your option. Let me give you an example: You are short a call option with the strike price of 1000. The underlying asset is an index and it’s price is 1050. This means your call option is 50 points ITM. If someone exercises your long call option, you will have to pay him/her the difference between the strike price and the underlying’s price which would be 50 (1050-1000). So the main difference between index and stock options is that you don’t have to buy/sell any shares of the underlying asset for index options. I hope this helps. Please let me know if you have any other questions or comments.

Can the same logic be applied for ETFs as it does Indexes? For example, if I trade the SPY ETF, would it be settled in cash?

Thanks! Johnson

Hi Johnson, Exercise and assignment for ETFs such as SPY work just like they do for equities. ETFs have shares that are openly traded, whereas indexes don’t. That’s why indexes are settled in cash, whereas ETFs aren’t. I hope this helps.

There are many articles online that I read that are biased against options tradings and I am a bit surprised to read a really helpful article like this. I find this helpful in understanding options trading, what are the techniques and how to manage the risks. Before, I was hesitant to try this financial game but now, after reading this article, I am considering participating with live accounts and no longer with a demo account. A few months ago, I signed up with a company called IQ Options, but really never involved real money and practiced only with a demo account.

Thanks for your comment. I am glad to see that you liked the post. However, I don’t recommend sing IQ Option to trade since they are a very shady trading firm. You could check out my Review of IQ Option for all the details.

this is a great and amazing article. i sincerely your effort creating time to write on such an informative article which has taught me a lot more on what is options assignment and avoiding it. i just started trading but had no ideas on this as a beginner. i find this article very helpful because it has given me more understanding on options trading and knowing the techniques and how to manage the risks. thanks for sharing this amazing article

You are very welcome

Hello, the first thing that i noticed when i opened this page is the beauty of the website. i am sure you have put much effort into creating this article and the details are really clear here. after watching the video break down, i fully understood the entire process on how to avoid options assignment.

Thank you so much for the positive feedback!

I would love to create a website like yours as the design used is really nice, simple and brings about clarity of the write ups, but then you wrote a brilliant article on how to avoid options assignment. great video here. it was confusing at first. i will suggest another video be added to help some people like me.

Thanks for the feedback. I recommend checking out my options trading beginner course . In it, I cover all the basics that weren’t explained here.

Thanks for your very helpful article. I am contemplating selling a call that would cover half my shares on company X. How can ensure that the assignment process selects the shares that I bought at a higher price, so as to maximize capital losses?

Hi Luis, When you are assigned, you just automatically buy/sell shares of the underlying at the strike price. This means your overall portfolio is adjusted by these 100 shares. The exact shares and your entry price are irrelevant. If you have 50 shares of X and your short call is assigned, you will sell 100 shares of X at the strike price. After this, your position would be -50 shares of X which would be equivalent to being short 50 shares of X. I hope this helps.

Louis, I entered a CALL butterfly spread at $100 below where I intended, just 2 days before expiration date. I intended to speculate on a big earning announcement jump the next day. It was a debit of 1.25. Also, when I realized my mistake, I tried to close it for anything at all. The Mark fluctuated between 40 and 70, but I could not get it to close. So now I am assigned to sell 200 share at 70 dollars below the market price of the stock. I am having a heart attack. I do not have the 200 shares to deliver, so it seems I have to buy them at the market, and sell them for $70 less, for a loss of $14,000.

What other options are open to me? Can my trading firm force a close with a friendly market maker and make it as if it happened on Friday? I am willing to pay a friendly market maker several hundred dollars to make this trade. Is that an option? Other options the trading firm can do for me that would cost me less than $14,000?

Hi Paul, Thanks for your comment. From the limited information provided, it is hard to say what is actually going on. If you bought a call butterfly spread, your max loss should be limited to the premium you paid to open the position. An assignment shouldn’t have a huge impact on your overall P&L. I highly recommend contacting your broker and explaining your situation to them since they have all the information required to evaluate what’s actually going on. But if the loss is real, there is no way for you to make a deal with a market maker to limit or undo potential losses. I hope this helps.

What happens with ITM long call option that typically gets automatically exercised at expiration, if the owner of the call option doesn’t have the cash/margin to cover the stock purchase?

He would receive a margin call

The Risks of Options Assignment

Any trader holding a short option position should understand the risks of early assignment. An early assignment occurs when a trader is forced to buy or sell stock when the short option is exercised by the long option holder. Understanding how assignment works can help a trader take steps to reduce their potential losses.

Understanding the basics of assignment

An option gives the owner the right but not the obligation to buy or sell stock at a set price. An assignment forces the short options seller to take action. Here are the main actions that can result from an assignment notice:

Short call assignment: The option seller must sell shares of the underlying stock at the strike price.
Short put assignment: The option seller must buy shares of the underlying stock at the strike price.

For traders with long options positions, it's possible to choose to exercise the option, buying or selling according to the contract before it expires. With a long call exercise, shares of the underlying stock are bought at the strike price while a long put exercise results in selling shares of the underlying stock at the strike price.

When a trader might get assigned

There are two components to the price of an option: intrinsic 1 and extrinsic 2 value. In the case of exercising an in-the-money 3 (ITM) long call, a trader would buy the stock at the strike price, which is lower than its prevailing price. In the case of a long put that isn't being used as a hedge for a long stock position, the trader shorts the stock for a price higher than its prevailing price. A trader only captures an ITM option's intrinsic value if they sell the stock (after exercising a long call) or buy the stock (after exercising a long put) immediately upon exercise.

Without taking these actions, a trader takes on the risks associated with holding a long or short stock position. The question of whether a short option might be assigned depends on if there's a perceived benefit to a trader exercising a long option that another trader has short. One way to attempt to gauge if an option could be potentially assigned is to consider the associated dividend. An options seller might be more likely to get assigned on a short call for an upcoming ex-dividend if its time value is less than the dividend. It's more likely to get assigned holding a short put if the time value has mostly decayed or if the put is deep ITM and close to expiration with a wide bid/ask spread on the stock.

It's possible to view this information on the Trade page of the thinkorswim ® trading platform. Review past dividends, the price of the short call, and the price of the put at the call's strike price. While past performance cannot be relied upon to continue, this information can help a trader determine whether assignment is more or less likely.

Reducing the risk associated with assignment

If a trader has a covered call that's ITM and it's assigned, the trader will deliver the long stock out of their account to cover the assignment.

A trader with a call vertical spread 4 where both options are ITM and the ex-dividend date is approaching may want to exercise the long option component before the ex-dividend date to have long stock to deliver against the potential assignment of the short call. The trader could also close the ITM call vertical spread before the ex-dividend date. It might be cheaper to pay the fees to close the trade.

Another scenario is a call vertical spread where the ITM option is short and the out-of-the-money (OTM) option is long. In this case, the trader may consider closing the position or rolling it to a further expiration before the ex-dividend date. This move can possibly help the trader avoid having short stock on the ex-dividend date and being liable for the dividend.

Depending on the situation, a trader long an ITM call might decide it's better to close the trade ahead of the ex-dividend date. On the ex-dividend date, the price of the stock drops by the amount of the dividend. The drop in the stock price offsets what a trader would've earned on the dividend and there would still be fees on top of the price of the put.

Assess the risk

When an option is converted to stock through exercise or assignment, the position's risk profile changes. This change could increase the margin requirements, or subject a trader to a margin call, 5 or both. This can happen at or before expiration during early assignment. The exercise of a long option position can be more likely to trigger a margin call since naked short option trades typically carry substantial margin requirements.

Even with early exercise, a trader can still be assigned on a short option any time prior to the option's expiration.

1 The intrinsic value of an options contract is determined based on whether it's in the money if it were to be exercised immediately. It is a measure of the strike price as compared to the underlying security's market price. For a call option, the strike price should be lower than the underlying's market price to have intrinsic value. For a put option the strike price should be higher than underlying's market price to have intrinsic value.

2 The extrinsic value of an options contract is determined by factors other than the price of the underlying security, such as the dividend rate of the underlying, time remaining on the contract, and the volatility of the underlying. Sometimes it's referred to as the time value or premium value.

3 Describes an option with intrinsic value (not just time value). A call option is in the money (ITM) if the underlying asset's price is above the strike price. A put option is ITM if the underlying asset's price is below the strike price. For calls, it's any strike lower than the price of the underlying asset. For puts, it's any strike that's higher.

4 The simultaneous purchase of one call option and sale of another call option at a different strike price, in the same underlying, in the same expiration month.

5 A margin call is issued when the account value drops below the maintenance requirements on a security or securities due to a drop in the market value of a security or when buying power is exceeded. Margin calls may be met by depositing funds, selling stock, or depositing securities. A broker may forcibly liquidate all or part of the account without prior notice, regardless of intent to satisfy a margin call, in the interests of both parties.

Assignment in Options Trading

Introduction articles, what is an options assignment.

In options trading , an assignment occurs when an option is exercised.

As we know, a buyer of an option has the right but not the obligation to buy or sell an underlying asset depending on what option they have purchased. When the buyer exercises this right, the seller will be assigned and will have to deliver or take delivery of what they are contractually obliged to. For stock options, it is typically 1 , 000 shares per contract for the UK ; and 100 shares per contract in the US.

As you can see, a buyer will never be assigned, only the seller is at risk of assignment. The buyer, however, may be auto exercised if the option expires in-the-money .

The Mechanics of Assignment

Assignment of options isn’t a random process. It’s a methodical procedure that follows specific steps, typically beginning with the option holder’s decision to exercise their option. The decision then gets routed through various intermediaries like brokers and clearing +houses before the seller is notified.

Exercise by Holder: The holder (buyer) of the option exercises their right to buy (for Call ) or sell (for Put ).
Random Assignment by a Clearing House: A clearing house assigns the obligation randomly among all sellers of the option.
Fulfilment by the Writer: The writer (seller) now must fulfill the obligation to sell (for Call) or buy (for Put) the underlying asset.

Option Assignments: Calls and Puts

Call option assignments.

When a call option holder chooses to exercise their right, the seller of the call option gets assigned. In such a situation, the seller is obligated to sell the underlying asset at the strike price to the call option holder.

Put Option Assignments

Similarly, if a put option holder decides to exercise their right, the put option seller gets assigned. The seller is then obligated to buy the underlying asset at the strike price from the put option holder.

The Implications of Assignments for Options Traders

Understanding assignment in options trading is crucial as it comes with potential risks and rewards for both parties involved.

For Option Sellers

Option sellers, or ‘writers,’ face the risk of unexpected assignments. The risk of being assigned early is especially present for options that are in the money or near their expiration date. We explain the difference between American and European assignments below.

For Option Holders

For option holders, deciding when to exercise an option (potentially leading to assignment) is a strategic decision. This decision must consider factors such as the intrinsic value of the option, the time value, and the dividend payment of the underlying asset.

Can Options be assigned before expiration?

In short, Yes, but it depends on the style of options you are trading.

American Style – Yes, this type of option can be assigned on or before expiry.

European Style – No, this type of option can only be assigned on the expiry date as defined in the contract specifications.

Options Assignment Example

For example, an investor buys XYZ PLC 400 call when the stock is trading at 385. The stock in the coming weeks rises to 425 after some good news, the buyer then decides to exercise their right early to buy the XYZ PLC stock at 400.

In this scenario, the call seller (writer) has been assigned and will have to deliver stock at 400 to the buyer (sell their stock at 400 when the prevailing market is 425).

An option typically would only be assigned if it is in the money, considering factors like dividends which do play an important role in exercise/assignments.

Can an Options Assignment be Prevented?

Assignment can sometimes come as a bit of a surprise but normally you should see it coming. You can only work to prevent assignment by closing the option before expiry or before any possible risk of assignment.

Managing Risks in Options Trading

While options trading can offer high returns, it is not devoid of risks. Therefore, understanding and managing these risks is key.

Buyers Risk: The premium paid for an option is at risk. If the option is not profitable at expiration, the premium is lost.

Writers Risk: The writer takes on a much larger risk. If a call option is assigned, they must sell the underlying asset at the strike price, even if its market price is higher.

Options Assignment Summary

The concept of ‘assignment’ in options trading, although complex, is a cornerstone of understanding options trading. It not only clarifies the responsibilities of an options seller but also helps the traders to gauge and manage their risks more effectively. Successful trading involves not just knowing your options but also understanding your obligations.

Options Assignment FAQs

What is options assignment.

Options assignment refers to the process by which the seller (writer) of an options contract is obligated to fulfill their contractual obligation to buy or sell the underlying asset, as specified by the terms of the options contract.

When does options assignment occur?

Options assignment can occur when the buyer of the options contract exercises their right to buy (in the case of a call option) or sell (in the case of a put option) the underlying asset before or at expiration .

How does options assignment work?

When a buyer exercises their options contract, a clearing house randomly assigns a seller who is short (has written) the same options contract to fulfill the obligations of the exercise.

What happens to the seller upon options assignment?

If assigned, the seller (writer) of the options contract is obligated to fulfill their contractual obligation by buying or selling the underlying asset at the specified price (strike price) per the terms of the options contract.

Can options be assigned before expiration?

Yes, options can be assigned at any time (depending on contract type) before expiration if the buyer chooses to exercise their right. However, it is more common for options to be assigned closer to expiration as the time value diminishes.

What factors determine options assignment?

Options assignment is determined by the buyer’s decision to exercise their options contract. They may choose to exercise if the options contract is in-the- money and it is financially advantageous for them to do so.

How can I avoid options assignment?

As a seller (writer) of options contracts, you can avoid assignment by closing your position before expiration through a closing trade (buying back the options contract) or rolling it over to a future expiration date.

What happens if I am assigned on a short call option?

If assigned on a short call option, you are obligated to sell the underlying asset at the specified price (strike price). This means you would need to deliver the shares . To fulfill this obligation, you may need to buy the shares in the open market if you do not hold them .

What happens if I am assigned on a short put option?

If assigned on a short put option, you are obligated to buy the underlying asset at the specified price (strike price). This means you would need to purchase the shares .

How does options assignment affect my account?

Options assignment can impact your account by requiring you to fulfill the obligations of the assigned options contract, which may involve buying or selling the underlying asset. It is important to have sufficient funds or margin available to cover these obligations.

OptionsDesk Tips & Considerations

You should always have enough funds in your account to cover any assignment risk. If you have a short call position and it is in-the-money at the time of an ex-dividend be aware of extra assignment risk here as buyer/holder of the option may look to exercise to qualify for the dividend. Assignments can happen at any time!

Option Exercise and Assignment Explained w/ Visuals

Last updated on February 11th, 2022 , 06:38 am

Buyers of options have the right to exercise their option at or before the option’s expiration. When an option is exercised, the option holder will buy (for exercised calls) or sell (for exercised puts) 100 shares of stock per contract at the option’s strike price.

Conversely, when an option is exercised, a trader who is short the option will be assigned 100 long (for short puts) or short (for short calls) shares per contract.

Long American style options can exercise their contract at any time.
Long calls transfer to +100 shares of stock
Long puts transfer to -100 shares of stock
Short calls are assigned -100 shares of stock.
Short puts are assigned +100 shares of stock.
Options are typically only exercised and thus assigned when extrinsic value is very low.
Approximately only 7% of options are exercised.

The following sequences summarize exercise and assignment for calls and puts (assuming one option contract ):

Call Buyer Exercises Option ➜ Purchases 100 shares at the call’s strike price.

Call Seller Assigned ➜ Sells/shorts 100 shares at the call’s strike price.

Put Buyer Exercises Option ➜ Sells/shorts 100 shares at the put’s strike price.

Put Seller Assigned ➜ Purchases 100 shares at the put’s strike price.

Let’s look at some specific examples to drill down on this concept.

Exercise and Assignment Examples

In the following table, we’ll examine how various options convert to stock positions for the option buyer and seller:

As you can see, exercise and assignment is pretty straightforward: when an option buyer exercises their option, they purchase (calls) or sell (puts) 100 shares of stock at the strike price . A trader who is short the assigned option is obligated to fulfill the opposite position as the option exerciser.

Automatic Exercise at Expiration

Another important thing to know about exercise and assignment is that standard in-the-money equity options are automatically exercised at expiration. So, traders may end up with stock positions by letting their options expire in-the-money.

An in-the-money option is defined as any option with at least $0.01 of intrinsic value at expiration . For example, a standard equity call option with a strike price of 100 would be automatically exercised into 100 shares of stock if the stock price is at $100.01 or higher at expiration.

What if You Don't Have Enough Available Capital?

Even if you don’t have enough capital in your account, you can still be assigned or automatically exercised into a stock position. For example, if you only have $10,000 in your account but you let one 500 call expire in-the-money, you’ll be long 100 shares of a $500 stock, which is a $50,000 position. Clearly, the $10,000 in your account isn’t enough to buy $50,000 worth of stock, even on 4:1 margin.

If you find yourself in a situation like this, your brokerage firm will come knocking almost instantaneously. In fact, your brokerage firm will close the position for you if you don’t close the position quickly enough.

Why Options are Rarely Exercised

At this point, you understand the basics of exercise and assignment. Now, let’s dive a little deeper and discuss what an option buyer forfeits when they exercise their option.

When an option is exercised, the option is converted into long or short shares of stock. However, it’s important to note that the option buyer will lose the extrinsic value of the option when they exercise the option. Because of this, options with lots of extrinsic value remaining are unlikely to be exercised. Conversely, options consisting of all intrinsic value and very little extrinsic value are more likely to be exercised.

The following table demonstrates the losses from exercising an option with various amounts of extrinsic value:

As we can see here, exercising options with lots of extrinsic value is not favorable.

Why? Consider the 95 call trading for $7. Exercising the call would result in an effective purchase price of $102 because shares are bought at $95, but $7 was paid for the right to buy shares at $95.

With an effective purchase price of $102 and the stock trading for $100, exercising the option results in a loss of $2 per share, or $200 on 100 shares.

Even if the 95 call was previously purchased for less than $7, exercising an option with $2 of extrinsic value will always result in a P/L that’s $200 lower (per contract) than the current P/L. F

or example, if the trader initially purchased the 95 call for $2, their P/L with the option at $7 would be $500 per contract. However, if the trader decided to exercise the 95 call with $2 of extrinsic value, their P/L would drop to +$300 because they just gave up $200 by exercising.

7% Of Options Are Exercised

Because of the fact that traders give up money by exercising an option with extrinsic value, most options are not exercised. In fact, according to the Options Clearing Corporation, only 7% of options were exercised in 2017 . Of course, this may not factor in all brokerage firms and customer accounts, but it still demonstrates a low exercise rate from a large sample size of trading accounts.

So, in almost all cases, it’s more beneficial to sell the long option and buy or sell shares instead of exercising. We like to call this approach a “synthetic exercise.”

Congrats! You’ve learned the basics of exercise and assignment. If you’d like to know how the exercise and assignment process actually works, continue to the next section!

Who Gets Assigned When an Option is Exercised?

With thousands of traders long and short options in the market, who actually gets assigned when one of the traders exercises their option?

In this section, we’ll run through the exercise and assignment process for options so you know how the assignment decision occurs.

If a trader is short a single option, how do they get assigned if one of a thousand other traders exercises that option?

The short answer is that the process is random. For example, if there are 5,000 traders who are long a call option and 5,000 traders who are short that call option, an account with the short option will be randomly assigned the exercise notice. The random process ensures that the option assignment system is fair

Visualizing Assignment and Exercise

The following visual describes the general process of exercise and assignment:

If you’d like, you can read the OCC’s detailed assignment procedure here (warning: it’s intense!).

Now you know how the assignment procedure works. In the final section, we’ll discuss how to quickly gauge the likelihood of early assignment on short options.

Assessing Early Option Assignment Risk

The final piece of understanding exercise and assignment is gauging the risk of early assignment on a short option.

As mentioned early, only 7% of options were exercised in 2017 (according to the OCC). So, being assigned on short options is rare, but it does happen. While a specific probability of getting assigned early can’t be determined, there are scenarios in which assignment is more or less likely.

The following scenarios summarize broad generalizations of early assignment probabilities in various scenarios:

In regards to the dividend scenario, early assignment on in-the-money short calls with less extrinsic value than the dividend is more likely because the dividend payment covers the loss from the extrinsic value when exercising the option.

All in all, the risk of being assigned early on a short option is typically very low for the reasons discussed in this guide. However, it’s likely that you will be assigned on a short option at some point while trading options (unless you don’t sell options!), but at least now you’ll be prepared!

What is assignment?

How does an investor know if an option position will be assigned?

Note: European-style options can only be exercised during a specified period just prior to expiration. In U.S. markets, the majority of options on commodity and index futures are European-style, while options on stocks and exchange-traded funds (ETF) are American-style. So, while SPDR S&P 500 , or SPY options, which are options tied to an ETF that tracks the S&P 500, are American-style options, S&P 500 Index options, or SPX options, which are tied to S&P 500 futures contracts, are European-style options.

What happens after an option is assigned?

How might an investor's account balance fluctuate after opening a short options position?

Understanding assignment risk in Level 3 and 4 options strategies

E*TRADE from Morgan Stanley

With all options strategies that contain a short option position, an investor or trader needs to keep in mind the consequences of having that option assigned , either at expiration or early (i.e., prior to expiration). Remember that, in principle, with American-style options a short position can be assigned to you at any time. On this page, we’ll run through the results and possible responses for various scenarios where a trader may be left with a short position following an assignment.

Before we look at specifics, here’s an important note about risk related to out-of-the-money options: Normally, you would not receive an assignment on an option that expires out of the money. However, even if a short position appears to be out of the money, it might still be assigned to you if the stock were to move against you just prior to expiration or in extended aftermarket or weekend trading hours. The only way to eliminate this risk is to buy-to-close the short option.

Short (naked) calls

Credit call spreads

Credit put spreads, debit call spreads, debit put spreads.

When all legs are in-the-money or all are out-of-the-money at expiration

Another important note : In any case where you close out an options position, the standard contract fee (commission) will be charged unless the trade qualifies for the E*TRADE Dime Buyback Program . There is no contract fee or commission when an option is assigned to you.

Short (naked) call

If it's at expiration	If it's at expiration
This means your account must be able to deliver shares of the underlying—i.e., sell them at the strike price. If your account doesn't have the buying power to cover the sale of shares, you may receive a margin call. Actions you can take: If you don’t want to sell your shares or you don’t own any, you can buy the call option before it expires, closing out the position and eliminating the risk of assignment.

If it's at expiration

This means your account must be able to deliver shares of the underlying—i.e., sell them at the strike price. If your account doesn't have the buying power to cover the sale of shares, you may receive a margin call.

Actions you can take: If you don’t want to sell your shares or you don’t own any, you can buy the call option before it expires, closing out the position and eliminating the risk of assignment.

If you experience an early assignment

An early assignment is most likely to happen if the call option is deep in the money and the stock’s ex-dividend date is close to the option expiration date.

If your account does not hold the shares needed to cover the obligation, an early assignment would create a short stock position in your account. This may incur borrowing fees and make you responsible for any dividend payments.

Also note that if you hold a short call on a stock that has a dividend payment coming in the near future, you may be responsible for paying the dividend even if you close the position before it expires.

If it's at expiration	If it's at expiration
This means your account must have enough money to buy the shares of the underlying at the strike price or you may incur a margin call. Actions you can take: If you don’t have the money to pay for the shares, you can buy the put option before it expires, closing out the position and eliminating the risk of assignment and the risk of a margin call.

An early assignment generally happens when the put option is deep in the money and the underlying stock does not have an ex-dividend date between the current time and the expiration of the option.

Short call + long call

(The same principles apply to both two-leg and four-leg strategies)

If the and the at expiration
This means your account will deliver shares of the underlying—i.e., sell them at the strike price. Actions you can take: If you don’t have the shares to sell, or don’t want to establish a short stock position, you can buy the short call before expiration, closing out the position. If the short leg is closed before expiration, the long leg may also be closed, but it will likely not have any value and can expire worthless.

If the and the at expiration

This means your account will deliver shares of the underlying—i.e., sell them at the strike price.

Actions you can take:

If you don’t have the shares to sell, or don’t want to establish a short stock position, you can buy the short call before expiration, closing out the position.

If the short leg is closed before expiration, the long leg may also be closed, but it will likely not have any value and can expire worthless.

This would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short and simultaneously sell the long leg of the spread.

Pay attention to short in-the-money call legs on the day prior to the stock’s ex-dividend date, because an assignment that evening would put you in a short stock position where you are responsible for paying the dividend. If there’s a risk of early assignment, consider closing the spread.

Short put + long put

If the and the at expiration
This means your account will buy shares of the underlying at the strike price. Actions you can take: If you don’t have the money to pay for the shares, or don’t want to, you can buy the put option before it expires, closing out the position and eliminating the risk of assignment. Once the short leg is closed, you can try to sell the long leg if it has any value, or let it expire worthless if it doesn’t.

If the and the at expiration

This means your account will buy shares of the underlying at the strike price.

Actions you can take:

If you don’t have the money to pay for the shares, or don’t want to, you can buy the put option before it expires, closing out the position and eliminating the risk of assignment.

Once the short leg is closed, you can try to sell the long leg if it has any value, or let it expire worthless if it doesn’t.

Early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

However, the long put still functions to cover the position because it gives you the right to sell shares at the long put strike price. Typically, you would sell the shares in the market and close out the long put simultaneously.

Here's a call example

Let’s say that you’re short a 100 call and long a 110 call on XYZ stock; both legs are in-the-money.
You receive an assignment notification on your short 100 call, meaning you sell 100 shares of XYZ stock at 100. Now, you have $10,000 in short stock proceeds, your account is short 100 shares of stock, and you still hold the long 110 call.
Exercise your long 110 call, which would cover the short stock position in your account.
Or, buy 100 shares of XYZ stock (to cover your short stock position) and sell to close the long 110 call.

Here's a put example:

Let’s say that you’re short a 105 put and long a 95 put on XYZ stock; the short leg is in-the-money.
You receive an assignment notification on your short 105 put, meaning you buy 100 shares of XYZ stock at 105. Now, your account has been debited $10,500 for the stock purchase, you hold 100 shares of stock, and you still hold the long 95 put.
The debit in your account may be subject to margin charges or even a Fed call, but your risk profile has not changed.
You can sell to close 100 shares of stock and sell to close the long 95 put.

Long call + short call

If the and the at expiration
This means your account will buy shares at the long call’s strike price. Actions you can take: If you don’t have enough money in your account to pay for the shares, or you don’t want to, you can simply sell the long call option before it expires, closing out the position. However, unless you are approved for Level 4 options trading, you must close out the short leg first (or simultaneously). The easiest way to do this is to use the spread order ticket to buy to close the short leg and sell to close the long leg. Assuming the short leg is worth less than $0.10, the E*TRADE Dime Buyback program would apply, and you’ll pay no commission to close that leg.

If the and the at expiration

This means your account will buy shares at the long call’s strike price.

Actions you can take:

If you don’t have enough money in your account to pay for the shares, or you don’t want to, you can simply sell the long call option before it expires, closing out the position.

However, unless you are approved for Level 4 options trading, you must close out the short leg first (or simultaneously). The easiest way to do this is to use the spread order ticket to buy to close the short leg and sell to close the long leg.

Assuming the short leg is worth less than $0.10, the E*TRADE Dime Buyback program would apply, and you’ll pay no commission to close that leg.

Debit spreads have the same early assignment risk as credit spreads only if the short leg is in-the-money.

An early assignment would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short share position and simultaneously sell the remaining long leg of the spread.

Long put + short put

If the and the at expiration
This means your account will buy shares at the long call’s strike price. Actions you can take: If you don’t have the shares, the automatic exercise would create a short position in your account. To avoid this, you can simply sell the put option before it expires, closing out the position. However, you may not have the buying power to close out the long leg unless you close out the short leg first (or simultaneously). The easiest way to do this is to use the spread order ticket to buy to close the short leg and sell to close the long leg. Assuming the short leg is worth less than $0.10, the E*TRADE Dime Buyback program would apply, and you’ll pay no commission to close that leg.

If the and the at expiration

This means your account will buy shares at the long call’s strike price.

Actions you can take:

If you don’t have the shares, the automatic exercise would create a short position in your account. To avoid this, you can simply sell the put option before it expires, closing out the position.

However, you may not have the buying power to close out the long leg unless you close out the short leg first (or simultaneously). The easiest way to do this is to use the spread order ticket to buy to close the short leg and sell to close the long leg.

Assuming the short leg is worth less than $0.10, the E*TRADE Dime Buyback program would apply, and you’ll pay no commission to close that leg.

An early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

All spreads that have a short leg

(when all legs are in-the-money or all are out-of-the-money)

If all legs are at expiration	If all legs are at expiration
For call spreads, this will buy shares at the long call’s strike price and sell shares at the short call’s strike price. For put spreads, this will sell shares at the long put strike price and buy shares at the short put strike price. In either case, this will happen in the account after expiration, usually overnight, and is called . Your account does not need to have money available to buy shares for the long call or short put because the sale of shares from the short call or long put will cover the cost. There will be no Fed call or margin call.

If all legs are at expiration

For call spreads, this will buy shares at the long call’s strike price and sell shares at the short call’s strike price.

For put spreads, this will sell shares at the long put strike price and buy shares at the short put strike price.

In either case, this will happen in the account after expiration, usually overnight, and is called .

What Is an Assignment?

Assignment most often refers to one of two definitions in the financial world:

The transfer of an individual's rights or property to another person or business. This concept exists in a variety of business transactions and is often spelled out contractually.
In trading, assignment occurs when an option contract is exercised. The owner of the contract exercises the contract and assigns the option writer to an obligation to complete the requirements of the contract.

Key Takeaways

Assignment is a transfer of rights or property from one party to another.
Options assignments occur when option buyers exercise their rights to a position in a security.
Other examples of assignments can be found in wages, mortgages, and leases.

Uses For Assignments

Assignment refers to the transfer of some or all property rights and obligations associated with an asset, property, contract, or other asset of value. to another entity through a written agreement.

Assignment rights happen every day in many different situations. A payee, like a utility or a merchant, assigns the right to collect payment from a written check to a bank. A merchant can assign the funds from a line of credit to a manufacturing third party that makes a product that the merchant will eventually sell. A trademark owner can transfer, sell, or give another person interest in the trademark or logo. A homeowner who sells their house assigns the deed to the new buyer.

To be effective, an assignment must involve parties with legal capacity, consideration, consent, and legality of the object.

A wage assignment is a forced payment of an obligation by automatic withholding from an employee’s pay. Courts issue wage assignments for people late with child or spousal support, taxes, loans, or other obligations. Money is automatically subtracted from a worker's paycheck without consent if they have a history of nonpayment. For example, a person delinquent on $100 monthly loan payments has a wage assignment deducting the money from their paycheck and sent to the lender. Wage assignments are helpful in paying back long-term debts.

Another instance can be found in a mortgage assignment. This is where a mortgage deed gives a lender interest in a mortgaged property in return for payments received. Lenders often sell mortgages to third parties, such as other lenders. A mortgage assignment document clarifies the assignment of contract and instructs the borrower in making future mortgage payments, and potentially modifies the mortgage terms.

A final example involves a lease assignment. This benefits a relocating tenant wanting to end a lease early or a landlord looking for rent payments to pay creditors. Once the new tenant signs the lease, taking over responsibility for rent payments and other obligations, the previous tenant is released from those responsibilities. In a separate lease assignment, a landlord agrees to pay a creditor through an assignment of rent due under rental property leases. The agreement is used to pay a mortgage lender if the landlord defaults on the loan or files for bankruptcy . Any rental income would then be paid directly to the lender.

Options Assignment

Options can be assigned when a buyer decides to exercise their right to buy (or sell) stock at a particular strike price . The corresponding seller of the option is not determined when a buyer opens an option trade, but only at the time that an option holder decides to exercise their right to buy stock. So an option seller with open positions is matched with the exercising buyer via automated lottery. The randomly selected seller is then assigned to fulfill the buyer's rights. This is known as an option assignment.

Once assigned, the writer (seller) of the option will have the obligation to sell (if a call option ) or buy (if a put option ) the designated number of shares of stock at the agreed-upon price (the strike price). For instance, if the writer sold calls they would be obligated to sell the stock, and the process is often referred to as having the stock called away . For puts, the buyer of the option sells stock (puts stock shares) to the writer in the form of a short-sold position.

Suppose a trader owns 100 call options on company ABC's stock with a strike price of $10 per share. The stock is now trading at $30 and ABC is due to pay a dividend shortly. As a result, the trader exercises the options early and receives 10,000 shares of ABC paid at $10. At the same time, the other side of the long call (the short call) is assigned the contract and must deliver the shares to the long.

Options Assignment

What is early options assignment what happens when options get assigned, options assignment - introduction, options assignment prior to expiration, options automatic exercise and assignment during expiration, can i avoid getting automatically exercised or assigned during expiration, what happens when long call options get automatically exercised.

Assuming you own 1 contract of $20 strike price call options on a stock trading at $30. During expiration, the call options are worth $10 and gets automatically exercised. That $10 x 100 = $1000 value completely disappears and you buy 100 shares of the underlying stock at $20 for $20 x 100 = $2000.

You are not losing out because now you have the rights to sell that stock at the market price of $30, so that $1000 lost is actually in that difference. You don't lose anything more than commissions when this options exercise happens.

What Happens When Short Call Options Get Automatically Exercised?

Assuming you wrote 1 contract of $20 strike price call options on a stock trading at $30 for $10.00. Days before expiration, the call options receives an options assignment. That option disappears, making you the full $10.00 x 100 = $1000 in profit and you receive 100 short shares at the price of $20. You would notice that you didn't really "make" that $1000 as you would still need to close the stock position by buying the stock at $30, which is a loss of $30 - $20 = $10 x 100 = $1000.

Assuming you own 100 shares of a stock trading at $30 and wrote 1 contract of $35 strike price call options for $1.00. Days before expiration, the stock rallies to $40 and the the short call options receives an options assignment. That option disappears along with your stocks. Your stocks get sold at $35 (even though the market price is $40) and you make $35 - $30 = $5 x 100 = $500 on your stocks and $1.00 x 100 = $100 on your short call options. So you lock in a total profit of $600 when that options assignment happens.

What Happens When Long Put Options Get Automatically Exercised?

Assuming you own 1 contract of $40 strike price put options on a stock trading at $30. During expiration, the put options are worth $10 and gets automatically exercised. That $10 x 100 = $1000 value completely disappears and you short 100 shares of the underlying stock at $40 for total value of $40 x 100 = $4000.

You are not losing out because now you can buy back that stock at the market price of $30 for a total of just $30 x 100 = $3000, clocking in the $1000 difference. You don't lose anything more than commissions when this options assignment happens.

Assuming you 100 shares of a stock trading at $30 and buys 1 contract of $30 strike price put options in order to protect those stocks for $1.00.

By expiration, the price of the stock falls to $20, bringing the put options in the money and gets automatically exercised.

The put options disappears and you lose $1.00 on the put options.

You sell your stocks at $30, losing nothing but commissions.

What Happens When Short Put Options Get Automatically Exercised?

>Assuming you wrote 1 contract of $40 strike price put options on a stock trading at $30 for $10.00. Days before expiration, the put options receives an options assignment. That option disappears with its full value making you the full $1000 value in profit and you receive stocks bought at the price of $40. You would notice that you didn't really profit from that $1000 as you would still need to close the stock position by selling the stock at $30, which is a loss of $40 - $30 = $10 x 100 = $1000.

Assuming you short 100 shares of a stock trading at $30 and wrote 1 contract of $25 strike price put options for $1.00. Days before expiration, the stock drops to $20 and the the short put options receives an options assignment. That option disappears along with your short stocks. Your stocks get closed off at $25 (even though the market price is $20) and you make $30 - $25 = $5 x 100 = $500 on your stocks and $1.00 x 100 = $100 on your short put options. So you lock in a total profit of $600 when that options assignment happens.

What is options assignment.

In short, an Options assignment is the random allocation of an exercise obligation to an Options writer.

An Equity options assignment is when the Options seller must fulfil the obligation of an Options contract by either selling or buying the underlying security at the exercise price. This is due to the buyer of an Options contract exercising their right to buy/sell the underlying security.

ASX Clear randomly selects (assigns) a seller of the contract to complete the obligations of the contract as follows:

Call sellers will sell the underlying stock at the exercise price.
Put sellers will buy the underlying stock at the exercise price.

If you are assigned an Equity Call Option and do not hold the underlying stock, you must purchase the required units no later than 2pm Sydney time on the following trading day.

If you are assigned an Equity Put Option and do not have sufficient cash to settle the stock purchase, you must sell the required units no later than 2pm Sydney time on the following trading day.

If you are assigned an Index Option , you must supply the cash settlement amount on the first ASX settlement day after expiry.

Please note : If the required units have not been purchased, CommSec may purchase the outstanding units at their discretion. CommSec will not be held liable for market movements of the underlying stock.

Trading Options: Understanding Assignment

OCC/OIC and FINRA collaborated to create this primer on options assignment.

DOWNLOAD ARTICLE (PDF)

The options market can seem to have a language of its own. To the average investor, there are likely a number of unfamiliar terms, but for an individual with a short options position—someone who has sold call or put options—there is perhaps no term more important than ‘assignment’ —the fulfilling of the requirements of an options contract.

When someone buys options to open a new position (Buy to Open), they are buying a right — either the right to buy the underlying security at a specified price (the strike price) in the case of a call option, or the right to sell the underlying security in the case of a put option.

On the flip side, when an individual sells, or writes, an option to open a new position (Sell to Open), they are accepting an obligation — either an obligation to sell the underlying security at the strike price in the case of a call option or the obligation to buy that security in the case of a put option. When an individual sells options to open a new position, they are said to be ‘short’ those options. The seller does this in exchange for receiving the option’s premium from the buyer.

American-style options allow the buyer of a contract to exercise at any time during the life of the contract, whereas European-style options can be exercised only during a specified period just prior to expiration. For an investor selling American-style options, one of the risks is that the investor may be called upon at any time during the contract’s term to fulfill its obligations. That is, as long as a short options position remains open, the seller may be subject to ‘assignment’ on any day equity markets are open.

What is assignment?

An option assignment represents the seller’s obligation to fulfill the terms of the contract by either selling or buying the underlying security at the exercise price. This obligation is triggered when the buyer of an option contract exercises their right to buy or sell the underlying security.

To ensure fairness in the distribution of American-style and European-style option assignments, The Options Clearing Corporation (OCC), which is the options industry clearing house, has an established process to randomly assign exercise notices to firms with an account that has a short option position. Once a firm receives an assignment, it then assigns this notice to one of its customers who has a short option contract of the same series. This short option contract is selected from a pool of such customers, either at random or by some other procedure specific to the brokerage firm.

How does an investor know if an option position will be assigned?

And while the majority of American-style options exercises (and assignments) happen on or near the contract’s expiration, a long options holder can exercise their right at any time, even if the underlying security is halted for trading. Someone may exercise their options early based upon a significant price movement in the underlying security or if shares become difficult to borrow as the result of a pending corporate action such as a buyout or takeover.

What happens after an option is assigned?

An investor who is assigned on a short option position is required to meet the terms of the written option contract upon receiving notification of the assignment. In the case of a short equity call, the seller of the option must deliver stock at the strike price and in return receives cash. An investor who doesn’t already own the shares will need to acquire and deliver shares in return for cash in the amount of the strike price, multiplied by 100, since each contract represents 100 shares. In the case of a short equity put, the seller of the option is required to purchase the stock at the strike price.

How might an investor’s account balance fluctuate after opening a short options position?

For example, say XYZ stock is trading at $40 and an investor sells 10 contracts for XYZ July 50 calls at $1.00, collecting a premium of $1,000, since each contract represents 100 shares ($1.00 premium x 10 contracts x 100 shares). Consider what happens if XYZ stock increases to $60, the call is exercised by the option holder and the investor is assigned. Should the investor not own the stock, they must now acquire and deliver 1,000 shares of XYZ at a price of $50 per share. Given the current stock price of $60, the investor’s short stock position would result in an unrealized loss of $9,000 (a $10,000 loss from delivering shares $10 below current stock price minus the $1,000 premium collected earlier).

Note: Even if the investor’s short call position had not been assigned, the investor’s account balance in this example would still be negatively affected—at least until the options expire if they are not exercised. The investor’s account position would be updated to reflect the investor’s unrealized loss—what they could lose if an option is exercised (and they are assigned) at the current market price. This update does not represent an actual loss (or gain) until the option is actually exercised and the investor is assigned.

What happens if an investor opened a multi-leg strategy, but one leg is assigned?

If an investor’s short option is assigned, the investor will be required to perform in accordance with their obligation to purchase or deliver the underlying security, regardless of the overall risk of their position when taking into account other options that may be owned as part of the overall multi-leg strategy. If the investor owns an option that serves to limit the risk of the overall spread position, it is up to the investor to exercise that option or to take other action to limit risk.

Marlins DFA No. 9 prospect Amaya

Club makes move to free up 40-man spot after acquiring rivera from d-backs.

Christina De Nicola

MIAMI – In a surprising move, the Marlins on Tuesday afternoon designated for assignment No. 9 prospect Jacob Amaya , who was once considered an option to be the franchise’s shortstop of the future.

Amaya was the corresponding move to make room on the 40-man roster following the acquisition of infielder Emmanuel Rivera from the Diamondbacks for cash.

If the player is claimed off waivers by another club, he is immediately added to that team's 40-man roster, at which point he can be optioned to the Minor Leagues (if he has options remaining) or assigned to his new team's 26-man roster.

The 25-year-old Amaya came over to the Marlins in the Miguel Rojas trade with the Dodgers on Jan. 11, 2023, after setting a career high with 17 homers between the Double-A and Triple-A levels of Los Angeles’ system in 2022. Miami elected to use veterans Joey Wendle, Jon Berti and Garrett Hampson at shortstop last season, though Amaya did make his big league debut and went 2-for-9 in four games.

Despite the departure of that trio, Amaya fell down the organizational depth chart when the Marlins signed veteran Tim Anderson and Minor Leaguer Tristan Gray. They also acquired Vidal Bruján from the Rays and Nick Gordon from the Twins.

Amaya was part of the second round of camp cuts after going 1-for-16 with one RBI, one caught stealing, one walk and seven strikeouts in 10 Grapefruit League games, though he did start at shortstop in the Spring Breakout exhibition.

In three games for Triple-A Jacksonville this season, Amaya hit 2-for-11 with two RBIs and two strikeouts. He started twice at shortstop and once at second base, committing one error and turning one double play in 18 innings at short.

According to MLB Pipeline’s scouting report, Amaya was arguably the best defensive shortstop in the upper levels of the organization -- including the Majors -- because of his smooth actions, quick and sure hands, a solid and accurate arm and a good internal clock. A right-handed hitter, Amaya was at his best when he kept his stroke under control and focused on getting on base. He would have lapses hunting home runs and chasing pitches.

Rivera, 27, hasn't appeared in the Majors this season and has a .684 OPS in 217 MLB games from 2021-23. He can play either of the corner infield positions.

Josh Bell is Miami’s primary first baseman, and primary third baseman Jake Burger has started at first when Bell has served as the designated hitter. Bruján and Jonah Bride, who started at the hot corner on Tuesday, are the only others to appear at third this season. Bruján and Rivera do not have Minor League options remaining, though Bride does.

“Every time we faced [Rivera], he killed us against lefties (.739 career OPS vs. LHP),” manager Skip Schumaker said, “so anticipate him being one of those options.”
