Delta Rebalancing

Delta Rebalancing is the act of buying or selling the underlying asset to bring a portfolio back to a target delta, usually zero. As the price of the underlying asset fluctuates, the delta of the options in a portfolio naturally drifts, causing the portfolio to become exposed to directional risk.

To mitigate this, traders perform rebalancing at specific intervals or when the delta exceeds a predefined threshold. In the high-speed environment of crypto derivatives, this is often handled by algorithms that monitor price movements in real time.

Efficient rebalancing minimizes the impact of transaction costs while ensuring that the portfolio remains protected against market moves. It is a mechanical process that bridges the gap between theoretical models and practical market execution.
