Equity options are sophisticated financial instruments that provide the buyer with the right, but not the obligation, to buy or sell a stock at a predetermined price within a specified time frame. This article delves into the intricacies of equity options, providing a historical context, types, key events, explanations, mathematical models, and more.
Historical Context
The origin of equity options can be traced back to ancient Greece, where philosopher Thales utilized an early form of options to secure the use of olive presses. Modern options trading began in 1973 with the establishment of the Chicago Board Options Exchange (CBOE).
Types of Equity Options
Call Options
A call option grants the buyer the right to purchase a stock at a predetermined price (strike price) before a specified expiration date.
Put Options
A put option gives the buyer the right to sell a stock at a predetermined price within the contract’s time frame.
Key Events in Equity Options History
- 1973: The Chicago Board Options Exchange (CBOE) was founded, marking the beginning of modern options trading.
- 1977: The CBOE introduced options on individual stocks.
- 1983: Index options became available, expanding the scope of options trading.
Detailed Explanations
How Equity Options Work
Equity options involve two main parties: the option writer (seller) and the option holder (buyer). The buyer pays a premium to the seller for the right to buy (call) or sell (put) the underlying stock at the strike price.
Mathematical Formulas/Models
Black-Scholes Model
The Black-Scholes model is used to estimate the price of an option. It involves the following formula:
Where:
- \( C \) = Call option price
- \( S_0 \) = Current stock price
- \( X \) = Strike price
- \( t \) = Time to expiration
- \( r \) = Risk-free interest rate
- \( N(d) \) = Cumulative distribution function of the standard normal distribution
