Gamma Scalping: Managing Option Gamma and Delta Exposure

Summary

The article introduces delta as option price sensitivity and gamma as the rate at which delta changes with the underlying price. It describes gamma scalping as repeatedly adjusting an options portfolio to manage its Greek exposures while seeking to benefit from short-term price movement. The workflow includes selecting a liquid, volatile underlying, establishing options positions, monitoring exposure, and evaluating adjustments with attention to risk controls.

A brief example discusses changing option holdings as the underlying moves, and a Python-oriented section outlines an at-the-money straddle, implied volatility and delta calculations, and combining straddle and futures profit and loss. The article reports cumulative returns of INR 1,000 for its example, but gives limited methodological detail in the provided text and does not establish general profitability. Its explanation also simplifies how gamma exposure changes; real outcomes depend on volatility, time decay, transaction costs, hedging frequency, and position construction.

Key ideas

• Delta measures an option’s price sensitivity to the underlying, while gamma measures how delta changes as the underlying moves.
• Gamma scalping involves adjusting options and potentially underlying exposure as market prices change.
• A workflow should account for liquidity, volatility, exposure monitoring, and risk controls.
• The described example combines an at-the-money straddle with futures profit and loss.
• The reported example result is not evidence that the approach will be profitable in other settings.
