Gamma risk management addresses the second-order sensitivity of an options portfolio, specifically focusing on how rapidly an options position’s delta changes in response to movements in the underlying asset’s price. When gamma is positive, delta increases as the underlying asset price rises and decreases as it falls, requiring a dynamic hedging approach. Ignoring this risk can lead to rapid and compounding losses, especially during periods of high market volatility.
Adjustment
Effective management requires frequent adjustments to maintain a delta-neutral position. A high gamma implies that the required hedge ratio changes rapidly, necessitating more frequent rebalancing of the underlying asset position. The cost of these adjustments, including transaction fees and slippage, is a significant consideration, particularly in high-frequency trading strategies.
Hedging
Quantitatively focused traders utilize advanced hedging strategies to mitigate gamma risk by trading a combination of options and the underlying asset. The objective is to minimize the portfolio’s overall sensitivity to large price swings. In automated systems, algorithms are implemented to continuously monitor and adjust positions, ensuring the overall portfolio remains within defined gamma exposure limits.
