Gamma risk refers to the exposure resulting from changes in an option’s delta as the underlying asset price fluctuates. High gamma indicates that the delta will change rapidly, making the position highly sensitive to small price movements. This risk is particularly pronounced for options near expiration and at-the-money, where delta changes most dramatically.
Sensitivity
Gamma measures the rate of change of delta relative to the underlying asset’s price. A positive gamma position benefits from increasing volatility, while negative gamma positions, typically held by option writers, face greater risk from rapid price shifts. Managing this sensitivity is crucial for maintaining a delta-neutral portfolio.
Hedge
The challenge of managing gamma risk requires dynamic hedging, where traders must frequently adjust their underlying asset position to maintain a delta-neutral portfolio. High gamma necessitates more frequent rebalancing, increasing transaction costs and execution risk. In volatile crypto markets, this dynamic adjustment can be particularly challenging due to high transaction fees and market microstructure effects.
