Dynamic hedging is a risk management strategy that involves continuously adjusting a portfolio’s hedge position in response to changes in market conditions. This approach aims to maintain a specific risk profile, typically delta neutrality, by frequently buying or selling the underlying asset. The strategy is particularly relevant for options traders seeking to mitigate exposure to price fluctuations over time.
Adjustment
The core principle of dynamic hedging relies on calculating and rebalancing the portfolio’s delta as the underlying asset price changes. As the delta of an option position fluctuates, the corresponding amount of underlying asset held for hedging must be adjusted to maintain neutrality. This continuous adjustment process minimizes the portfolio’s sensitivity to small price movements.
Rebalance
Rebalancing frequency is a critical parameter in dynamic hedging, balancing transaction costs against hedging accuracy. High-frequency rebalancing reduces tracking error but increases costs, while infrequent rebalancing saves on fees but exposes the portfolio to greater risk during large price swings. The effectiveness of dynamic hedging depends heavily on market liquidity and the cost of execution.
