Definition
Gamma Neutrality refers to an options trading strategy where a portfolio is structured in such a way that the gamma (the rate of change of delta) is zero. This means that despite large movements in the underlying asset’s price, the delta of the options position remains constant. This concept is essential for traders who want to immunize their portfolios from drastic changes in the underlying asset, effectively insulating themselves from excess risk.
Gamma Neutral vs Delta Neutral
| Aspect | Gamma Neutral | Delta Neutral |
|---|---|---|
| Definition | Portfolio has zero gamma | Portfolio has zero delta |
| Change with Underlying | Delta remains unchanged despite moves | Delta changes with the underlying |
| Strategy | Achieved through adding options | Primarily achieved through balance |
| Purpose | Protects from large swings | Locks in profits at a specific delta |
Examples
- If a trader has a portfolio with a long call option and the underlying stock increases, the delta increases. To achieve gamma neutrality, the trader may purchase an additional put option.
