The Difference Between American and European Options

In this article we get the difference between the American and European Options. and how American and European Options works.

When it comes to options trading, there are two primary types: American options and European options. While both provide investors with the right to buy or sell an underlying asset at a predetermined price, there are some key differences between these two types of options. In this article, we will explore the variations, benefits, and considerations associated with American and European options.

Definition of American Options

American options are derivative contracts that grant the holder the flexibility to exercise their rights at any time before the option’s expiration date. This means that the option holder has the freedom to buy or sell the underlying asset at the strike price whenever they choose, up until the option’s expiration. The ability to exercise the option at any point during its lifetime gives American options their inherent value and versatility.

Definition of European Options

On the other hand, European options are derivative contracts that only allow the holder to exercise their rights at the expiration date of the option. Unlike American options, European options do not offer the same flexibility in terms of early exercise. The option holder must wait until the expiration date to either buy or sell the underlying asset at the agreed-upon strike price.

Key Differences

The primary distinction between American and European options lies in the exercise flexibility:

American call option is priced equal to European call. Though it seems that flexibility of American option should be more valuable than the necessity of exercising on maturity. By exercising early one realizes only the intrinsic value and foregoes time value. An option would always have some time value as long as there is time left for its expiration. Selling a call is would fetch more value than exercising it, and hence one would always sell rather than exercise, till maturity. Therefore American call would be priced same as European call.

Exercise Flexibility:

  • American options: The holder can exercise the option at any time before the expiration date.
  • European options: The holder can only exercise the option on the expiration date.

Trading Styles:

  • American options: Suited for traders who want the flexibility to adjust their positions or take advantage of market conditions by exercising the option before expiration.
  • European options: More appropriate for investors who prefer to hold the option until expiration and are less concerned with interim price fluctuations.

Pricing Differences:

  • The pricing of American and European options can also vary due to the exercise flexibility of American options. The ability to exercise early can add extra value to American options compared to their European counterparts.

Considerations for Traders and Investors

When deciding between American and European options, it is essential to consider several factors:

Trading Objectives:

  • Traders seeking greater flexibility and the ability to react quickly to market movements may prefer American options.
  • Investors with longer-term strategies and less concern about interim price fluctuations may find European options more suitable.

Premiums and Costs:

  • American options generally have higher premiums compared to European options due to their added flexibility.

Liquidity and Market Depth:

  • Depending on the specific options contract, liquidity and market depth may vary between American and European options. It is crucial to consider these factors before entering a trade.


In summary, the main difference between American and European options lies in the exercise flexibility they offer. American options provide the freedom to exercise at any time before expiration, while European options can only be exercised at the expiration date. Traders and investors should carefully evaluate their objectives, risk tolerance, and market conditions to determine which type of option is most suitable for their needs. Understanding these differences empowers market participants to make informed decisions when engaging in options trading.
