10.2.1 Equity Derivatives

Introduction to Equity Derivatives

Equity derivatives are financial instruments whose value is linked to the price movements of underlying equities such as individual stocks or stock indexes. These derivatives play a crucial role in the world of finance, providing both opportunities and risks to participants in the equity markets. Among the most common equity derivatives are stock options and stock futures. They are fundamental tools used by investors for hedging portfolios, enhancing returns, or speculating on future price movements.

Stock Options

A stock option is a contract that gives the holder the right, but not the obligation, to buy or sell a specific amount of a stock at a predetermined price (known as the strike price) within a specified period. Options are of two main types: calls and puts.

• Call Options: Grant the holder the right to buy a stock at the strike price.
• Put Options: Grant the holder the right to sell a stock at the strike price.

Key Features:

1. Expiration Date: All options have a fixed expiration date, which is the last day the option can be exercised.
2. Premium: The price paid for purchasing the option, representing the cost of acquiring the option’s potential benefits.
3. Intrinsic and Extrinsic Value:
   • Intrinsic Value: The difference between the stock’s current price and the strike price, when favorable to the option holder.
   • Extrinsic Value: The remaining part of the premium, derived from the option’s time value and volatility of the underlying stock.

Usage:

• Hedging: Protecting against potential declines in stock prices.
• Speculation: Gaining potential profit from anticipated stock price changes without owning the stock.

Stock Futures

Stock futures involve contracts to buy or sell a specific amount of a stock or a stock index at a predetermined price on a future date. Unlike options, futures contracts obligate the parties involved to execute the contract terms upon expiration.

Characteristics:

1. Standardization: Futures contracts are standardized in terms of quantity, delivery time, and terms.
2. Margin Requirement: The buyer and seller must post an initial margin, which serves as a performance bond.
3. Mark-to-Market: Daily adjustment of the futures account to reflect gains and losses.

Usage:
