Early Assignment: Finance Explained

Sarah Saves

Early assignment in the context of stock options is a scenario where the seller (writer) of an option is required to fulfill the terms of the option contract before its expiration date. This occurs when the holder of an American-style option (either a call or a put) decides to exercise the option prematurely, compelling the option writer to buy (in case of a put option) or sell (in case of a call option) the underlying asset at the specified strike price.

The Process of Assignment

The assignment process is initiated when an option holder exercises their right under the contract. In the case of American-style options, this can happen at any time before the option expires, giving rise to the possibility of early assignment. When an exercise notice is filed by the option holder, the Options Clearing Corporation (OCC) randomly selects a member firm that holds a short position in that series of options. The member firm then selects an investor, typically using a random process or a first-in, first-out method, who has written (sold) those options to fulfill the obligation.

Who Gets Assigned

Because the assignment process is random, any writer of that particular option series can be selected for assignment. This means that if you have sold an American-style option, there is always a risk of being assigned at any time prior to expiration, especially if the option is deeply in-the-money or if a significant event, like a dividend payment, is forthcoming.

Implications of Early Assignment

Early assignment can have significant implications for the option writer. For call option writers, it may mean delivering the stock and potentially missing out on further gains or dividends. For put option writers, it may mean purchasing the stock at the strike price, which could be higher than the current market price. Option writers need to be prepared for this possibility by having the necessary liquidity or stock availability to meet the assignment requirements.

Conclusion

Early assignment is an important consideration in options trading, particularly for those writing American-style options. While it can introduce unexpected obligations, understanding the assignment process and managing positions proactively can help traders and investors navigate these situations effectively. Being aware of the conditions that increase the likelihood of early assignment, such as dividends and in-the-money options, is crucial for anyone involved in the options market.
