Gamma scalping is an options trading strategy where a trader profits from changes in an option’s delta by continuously rebalancing their position in the underlying asset. The strategy involves maintaining a delta-neutral position, meaning the overall portfolio value is insensitive to small changes in the underlying asset price. This technique aims to capture profits from the option’s gamma, which measures the rate of change of delta.
Volatility
The profitability of gamma scalping is directly linked to market volatility. The strategy performs optimally in high-volatility environments where frequent price movements allow the trader to buy low and sell high on the underlying asset as they rebalance their delta. In low-volatility conditions, the cost of rebalancing often exceeds the profits generated by gamma.
Adjustment
The core process involves dynamically adjusting the position in the underlying asset to maintain delta neutrality. When the underlying asset price rises, the delta of a long option position increases, requiring the trader to sell some of the underlying asset to return to a neutral state. This continuous adjustment process allows the trader to capture profits from the option’s positive gamma.
