Cross-Gamma Hedging
Cross-gamma hedging is a strategy used to manage the risk of multiple correlated assets by adjusting the gamma of a portfolio across those assets. Instead of hedging each option position individually, a trader considers the correlations between the underlying assets and hedges the aggregate gamma risk.
This is particularly relevant in cryptocurrency markets, where many assets exhibit high correlation during market moves. By accounting for these correlations, a trader can reduce the number of transactions required to maintain delta neutrality and lower overall execution costs.
It requires a deep understanding of the joint price dynamics and the ability to model the sensitivity of the entire portfolio to shifts in the underlying assets. This approach is more efficient than single-asset hedging but introduces complexity and potential model risk if correlations break down.
It is a sophisticated technique for managing risk in multi-asset derivatives portfolios.
