Understanding Delta Neutral Strategies
Delta-neutral strategies are investment approaches where the portfolio's overall delta equals zero, meaning the portfolio remains unaffected by price changes in the underlying asset. These strategies allow investors to profit without needing to predict market movements.
Four Common Delta Neutral Strategies
- Long Straddle
- Short Strangle
- Long Call Butterfly
- Short Put Spread
Each strategy serves different market conditions and risk appetites. Let's explore them in detail.
Key Components of Delta Neutral Strategies
Delta Explained
Delta measures an option's sensitivity to changes in the underlying asset's price. A delta of 0.5 means the option's price will move $0.50 for every $1 move in the underlying asset.
Gamma Considerations
Gamma indicates how delta changes with the underlying asset's price movement. High gamma positions require more frequent rebalancing to maintain delta neutrality.
