Introduction
The exercise price, also known as the strike price or striking price, is the predetermined price at which an option holder can buy (in the case of a call option) or sell (in the case of a put option) the underlying asset. It is a fundamental concept in options trading and plays a crucial role in the profitability and risk management of options contracts.
Historical Context
Options trading dates back to ancient civilizations, but the modern financial options market as we know it today began to take shape in the 1970s. The establishment of the Chicago Board Options Exchange (CBOE) in 1973 marked a significant milestone. The concept of exercise price has since become a pivotal element in the valuation and trading of options.
Types of Options and Their Exercise Prices
- Call Options: Gives the holder the right to buy the underlying asset at the exercise price.
- Put Options: Gives the holder the right to sell the underlying asset at the exercise price.

Detailed Explanation
Importance and Applicability
The exercise price is critical in determining the intrinsic value of an option:
- In-the-Money (ITM): When the market price of the underlying asset is favorable compared to the exercise price.
- Call Option: Market price > Exercise price
- Put Option: Market price < Exercise price
- At-the-Money (ATM): When the market price equals the exercise price.
- Out-of-the-Money (OTM): When the market price is not favorable compared to the exercise price.
- Call Option: Market price < Exercise price
- Put Option: Market price > Exercise price
Mathematical Models
The valuation of options heavily relies on mathematical models such as the Black-Scholes model and the Binomial options pricing model. These models incorporate the exercise price to determine the theoretical price of an option.

Examples and Considerations

- Example of a Put Option: An investor holds a put option with an exercise price of $100. If the underlying asset’s market price falls to $80, the option is in-the-money.
