Definition: Equity derivatives are financial instruments whose value is based on the equity movements of underlying assets. For example, stock options are a type of equity derivative because their value is based on the price movements of the related stock. Investors can use equity derivatives to hedge against risks associated with holding or shorting stocks, or to speculate on the price movements of the underlying assets.
Origin: The origin of equity derivatives can be traced back to the 1970s when the Chicago Board Options Exchange (CBOE) introduced standardized stock option contracts. This innovation allowed investors to manage risk more effectively and provided more liquidity to the market. Over time, the types and complexity of equity derivatives have increased, covering more underlying assets and trading strategies.
Categories and Characteristics: Equity derivatives can be mainly categorized into the following types:
- Stock Options: These are the most common equity derivatives, giving the holder the right to buy or sell a stock at a specific price within a specific time frame. They are highly flexible and can be used for hedging or speculation.
- Stock Futures: These are another common type of equity derivative, requiring the buyer and seller to trade a stock at a predetermined price on a future date. They are characterized by standardized contracts and high transparency in trading.
- Index Futures and Options: These derivatives are based on stock indices, such as the S&P 500. They allow investors to speculate on or hedge against the overall market movements.
Specific Cases:
- Case 1: Suppose Investor A holds a large number of shares in a company but is concerned about a short-term price decline. A can buy put options on the stock to hedge against potential price drops. If the stock price indeed falls, A can exercise the options to sell the shares, thereby minimizing losses.
- Case 2: Investor B believes that the stock price of a tech company will rise significantly in the coming months but does not want to buy the stock directly. B can purchase call options on the company’s stock. If the stock price rises as expected, B can buy the stock at the lower strike price and then sell it at the higher market price, thus making a profit.
