Exercised option: Explained | TIOmarkets
BY TIO Staff
|July 5, 2024In the world of trading, the term 'exercised option' is frequently used, but not always fully understood. This glossary entry aims to demystify this term and provide a comprehensive understanding of what it means, how it works, and its relevance in the trading market. The term 'exercised option' is a fundamental concept in options trading, and a thorough understanding of it is crucial for traders to make informed decisions.
Options trading is a type of derivative trading that involves buying or selling the right to buy or sell a specific asset at a predetermined price within a specified time frame. An 'exercised option' refers to the action of the option holder when they decide to use their right to buy or sell the underlying asset. This article will delve into the intricacies of exercised options, providing detailed explanations and examples to help traders understand this concept better.
Understanding Options
Before we delve into the concept of an exercised option, it's essential to understand what options are. Options are financial derivatives that give the buyer the right, but not the obligation, to buy or sell an underlying asset at a specific price on or before a certain date. The buyer of an option pays a premium to the seller (or writer) of the option for this right.
Options come in two types: call options and put options. A call option gives the holder the right to buy the underlying asset, while a put option gives the holder the right to sell the underlying asset. Both types of options can be exercised, which leads us to the concept of an exercised option.
Call Options
A call option is a contract that gives the holder the right to buy a specific amount of an underlying asset at a predetermined price (the strike price) within a certain time frame. The holder of a call option is betting that the price of the underlying asset will rise above the strike price before the option expires.
If the price of the underlying asset does rise above the strike price, the holder can exercise the option, buying the asset at the strike price and then selling it at the higher market price for a profit. If the price of the underlying asset does not rise above the strike price before the option expires, the holder may choose not to exercise the option, in which case the option would expire worthless.
Put Options
A put option, on the other hand, gives the holder the right to sell a specific amount of an underlying asset at a predetermined price within a certain time frame. The holder of a put option is betting that the price of the underlying asset will fall below the strike price before the option expires.
If the price of the underlying asset does fall below the strike price, the holder can exercise the option, selling the asset at the strike price and then buying it back at the lower market price for a profit. If the price of the underlying asset does not fall below the strike price before the option expires, the holder may choose not to exercise the option, in which case the option would expire worthless.
Exercising an Option
Exercising an option means that the holder of the option decides to use their right to buy or sell the underlying asset at the strike price. This decision is typically based on whether doing so would result in a profit. If exercising the option would result in a loss, the holder would typically choose not to exercise the option, allowing it to expire worthless.
The process of exercising an option varies depending on the type of option and the trading platform. In some cases, the holder may need to manually exercise the option, while in other cases, the option may be automatically exercised if it is in the money (meaning that exercising the option would result in a profit) at the time of expiration.
When to Exercise an Option
The decision to exercise an option is typically based on whether doing so would result in a profit. If the market price of the underlying asset is higher than the strike price for a call option, or lower than the strike price for a put option, then exercising the option would result in a profit.
However, the holder also needs to consider the premium paid for the option. Even if exercising the option would result in a profit based on the difference between the market price and the strike price, the holder would still need to subtract the premium paid for the option to determine the net profit. If the net profit would be negative, the holder would typically choose not to exercise the option.
How to Exercise an Option
The process of exercising an option varies depending on the trading platform and the type of option. For American-style options, which can be exercised at any time before expiration, the holder would typically need to submit an exercise notice to their broker. The broker would then process the exercise notice and execute the transaction.
For European-style options, which can only be exercised at expiration, the option would typically be automatically exercised if it is in the money at the time of expiration. If the option is out of the money (meaning that exercising the option would result in a loss) at the time of expiration, it would typically expire worthless.
Implications of Exercising an Option
Exercising an option has several implications for both the holder and the writer of the option. For the holder, exercising an option can result in a profit if the market price of the underlying asset is favorable compared to the strike price. However, the holder also needs to consider the premium paid for the option, as this can affect the net profit.
For the writer of the option, being assigned (meaning that the holder has decided to exercise the option) can result in a loss if the market price of the underlying asset is unfavorable compared to the strike price. However, the writer also receives the premium paid by the holder, which can offset some or all of the loss.
Implications for the Holder
For the holder, the main benefit of exercising an option is the potential for profit. If the market price of the underlying asset is higher than the strike price for a call option, or lower than the strike price for a put option, then exercising the option would result in a profit. However, the holder also needs to consider the premium paid for the option, as this can affect the net profit.
Another implication for the holder is the potential for loss. If the holder decides to exercise the option and the market price of the underlying asset is unfavorable compared to the strike price, the holder could incur a loss. Additionally, if the holder chooses not to exercise the option and it expires worthless, the holder would lose the premium paid for the option.
Implications for the Writer
For the writer of the option, being assigned can result in a loss if the market price of the underlying asset is unfavorable compared to the strike price. However, the writer also receives the premium paid by the holder, which can offset some or all of the loss.
Another implication for the writer is the potential for profit. If the holder chooses not to exercise the option and it expires worthless, the writer would keep the premium paid by the holder as profit. However, the writer also takes on the risk of potentially unlimited losses if the market price of the underlying asset moves significantly against the writer's position.
Conclusion
Understanding the concept of an exercised option is crucial for anyone involved in options trading. This term refers to the action of the option holder when they decide to use their right to buy or sell the underlying asset at the strike price. The decision to exercise an option is typically based on whether doing so would result in a profit.
Exercising an option has several implications for both the holder and the writer of the option. For the holder, exercising an option can result in a profit if the market price of the underlying asset is favorable compared to the strike price. For the writer, being assigned can result in a loss if the market price of the underlying asset is unfavorable compared to the strike price.
By understanding the concept of an exercised option and the implications of exercising an option, traders can make more informed decisions and potentially increase their chances of success in the options market.
