An equity derivative is a financial trading instrument whose value is derived from the price movements of an underlying equity asset. Equity derivatives can include a wide range of financial contracts such as options, futures, swaps, and forward contracts. These instruments allow investors to hedge risks, speculate on price movements, or increase leverage.
Types of Equity Derivatives
Options
Options give the holder the right, but not the obligation, to buy or sell an underlying equity asset at a predetermined price within a specified time frame.
- Call Options: These confer the right to buy the asset.
- Put Options: These confer the right to sell the asset.
Futures
Futures are contracts to buy or sell an underlying asset at a future date at a predetermined price. Unlike options, both parties are obligated to execute the contract.
Swaps
Equity swaps involve the exchange of future cash flows between two parties, where at least one of the cash flow streams is linked to an underlying equity asset.
Forward Contracts
Similar to futures, forward contracts are agreements to buy or sell an asset at a future date for a price agreed upon today. Unlike futures, forwards are customizable and traded over-the-counter (OTC).
How Are Equity Derivatives Used?
Hedging
Investors use equity derivatives to mitigate risks associated with the price movements of underlying equity assets. For instance, they can hedge a long position in a stock by buying put options.
Speculation
Traders often use equity derivatives to speculate on the future direction of stock prices, profiting from price changes without actually owning the underlying stock.
Arbitrage
Arbitrage opportunities arise when there are pricing inefficiencies in the market. Traders can exploit these inefficiencies by simultaneously buying and selling related derivative contracts.
Leverage
Equity derivatives allow for high leverage, enabling investors to control large positions with relatively small amounts of capital. This amplifies both potential gains and losses.
Examples of Equity Derivatives
Example 1: Using Call Options
An investor believes that the stock of XYZ Corporation will increase in value from its current price of $50 per share. They purchase a call option with a strike price of $55 expiring in three months. If the stock price rises to $60, the investor can buy the stock at $55, thus gaining $5 per share (excluding the premium paid for the option).
Example 2: Utilizing Futures Contracts
A trader enters into a futures contract to buy 100 shares of ABC Corporation at $200 per share in three months. If the price of ABC shares rises to $220, the trader benefits from the lower purchase price agreed upon in the futures contract.
Historical Context
Equity derivatives have been an integral part of the financial markets since the early 1980s. The development of complex mathematical models, such as the Black-Scholes model, facilitated the widespread adoption of options trading. Over time, the market for equity derivatives has grown exponentially, becoming an essential tool for both institutional and retail investors.
