Gamma Scalping Strategies
Gamma scalping is an advanced options trading strategy that capitalizes on the relationship between an option's delta changes and underlying price movements. Traders use this strategy to profit from frequent rebalancing of delta-hedged positions, particularly during periods of high volatility.
Understanding gamma scalping
Gamma scalping is a market-neutral strategy that focuses on profiting from an option's gamma rather than taking directional bets. The strategy involves:
- Maintaining a delta-neutral position
- Actively adjusting the hedge as prices move
- Profiting from the accumulated small gains from frequent rebalancing
The effectiveness of gamma scalping depends on price movements being large enough to justify rehedging costs while managing various risks including transaction cost impact.
How gamma scalping works
Key components of gamma scalping
Position setup
Traders typically establish positions with positive gamma exposure, often through:
- Long at-the-money options
- Option spreads with net positive gamma
- Multi-strike positions to maintain gamma exposure across price ranges
Rebalancing thresholds
Successful gamma scalping requires careful consideration of:
- Minimum price moves for rehedging
- Transaction cost modeling impact
- Market impact cost assessment
- Optimal rebalancing frequency
