A European option is a financial derivative that grants the holder the right, but not the obligation, to buy or sell an underlying asset at a specified price only on its expiration date. This characteristic differentiates European options from American options, which can be exercised at any point before or on the expiry date.
Historical Context
The concept of options dates back to ancient Greece but gained significant prominence in modern finance in the 1970s with the advent of formalized options markets such as the Chicago Board Options Exchange (CBOE). European options are often cited in academic literature because they simplify the mathematical modeling of options prices due to their single exercise date.
Types/Categories
- European Call Option: The right to buy the underlying asset at a predetermined price on the expiry date.
- European Put Option: The right to sell the underlying asset at a predetermined price on the expiry date.
Key Events
- 1973: The Black-Scholes Model was introduced, primarily for pricing European options.
- 2000: The advent of electronic trading platforms expanded access to European options.
Detailed Explanations
Mathematical Formulas/Models
Black-Scholes Model:
The Black-Scholes formula is pivotal in calculating the price of European options:
Where:
- \( C \) = Call option price
- \( S_0 \) = Current stock price
- \( X \) = Strike price
- \( r \) = Risk-free interest rate
- \( T \) = Time to maturity
- \( N() \) = Cumulative distribution function of the standard normal distribution
- \( d_1 = \frac{\ln(\frac{S_0}{X}) + (r + \frac{\sigma^2}{2})T}{\sigma \sqrt{T}} \)
- \( d_2 = d_1 - \sigma \sqrt{T} \)
- \( \sigma \) = Volatility of the stock’s returns
