American options

Definition

American options are financial derivatives that give the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price up until the expiration date. Unlike European options, which can only be exercised at expiration, American options offer more flexibility as they can be exercised at any time before or on the expiration date, making them generally more valuable in terms of potential profit and risk management.

Review Questions

• How does the ability to exercise American options at any time before expiration provide advantages over European options?
  • The ability to exercise American options at any time before expiration allows holders to react quickly to market changes and capitalize on favorable price movements. This flexibility means that if the market price of the underlying asset increases significantly, the option holder can exercise their option immediately rather than waiting until expiration, thus maximizing potential profit. This key difference contributes to American options generally having higher premiums compared to European options.
• Discuss how American options can be used in hedging strategies compared to European options.
  • American options enhance hedging strategies due to their flexibility in exercise timing. Investors can use American call or put options to protect against adverse price movements by exercising them whenever conditions become favorable. This capability allows for dynamic adjustments in response to market volatility, making American options more suitable for active risk management compared to European options that limit exercise until expiration.
• Evaluate the implications of American options' flexibility on their pricing models and market behavior.
  • The flexibility of American options impacts their pricing models significantly because it introduces additional variables related to timing and early exercise. For example, pricing models must account for the possibility of exercising the option at any moment rather than just at maturity. This increased complexity influences market behavior as traders may speculate on potential price swings and volatility, leading to varied strategies that reflect an investor's outlook on both the underlying asset and market conditions. The result is that American options often trade at higher premiums due to this added value from exercise flexibility.
