A “leg” in derivatives trading refers to one component of a trading strategy where a trader combines multiple options contracts or multiple futures contracts. Each leg in a multi-leg strategy can have different strike prices, expiration dates, or types (e.g., calls and puts).
How a Leg Works
In the context of derivatives, a leg represents a single position within a combination of trades. Multi-leg strategies are often employed to hedge risks, enhance returns, or capitalize on market inefficiencies.
Single-Leg vs. Multi-Leg Strategies
- Single-Leg Strategy: Involves taking a position in a single option or futures contract.
- Multi-Leg Strategy: Involves taking positions in two or more options or futures contracts simultaneously.
Types of Multi-Leg Strategies
There are several common multi-leg strategies used in derivatives trading, each serving different purposes:
Call and Put Spreads
- Vertical Spread: Combines two options with the same expiration date but different strike prices.
- Horizontal Spread (Time Spread): Combines options with the same strike price but different expiration dates.
- Diagonal Spread: Combines options with different strike prices and expiration dates.
Straddles and Strangles
- Straddle: Involves buying or selling both a call and a put option with the same strike price and expiration date.
- Strangle: Involves buying or selling both a call and a put option with different strike prices but the same expiration date.
