Gamma Scalping Efficiency
Gamma Scalping Efficiency is the measure of how effectively a trader manages the delta of an options portfolio by frequently buying or selling the underlying asset to remain delta-neutral. Gamma represents the rate of change of an option's delta with respect to the underlying price, and scalping aims to capture profits from the movement of the underlying that causes the delta to fluctuate.
High efficiency in this process means minimizing transaction costs and slippage while successfully harvesting the volatility premium. It requires precise timing and rapid execution to rebalance the hedge as the underlying price moves.
This strategy is essential for market makers who seek to earn income from the difference between implied and realized volatility. Effective gamma scalping requires a deep understanding of market microstructure and liquidity.
