Dynamic Rebalancing Error

Dynamic rebalancing error occurs when the discrete timing of portfolio adjustments fails to capture the continuous nature of theoretical hedging requirements. Models like Black-Scholes assume that a trader can adjust their hedge ratio instantaneously and continuously.

In reality, traders must rebalance at specific intervals or price thresholds, leaving the portfolio exposed to price changes between these moments. If volatility spikes unexpectedly, the lag in rebalancing can lead to significant losses or unintended directional exposure.

This error is a fundamental constraint in implementing delta-neutral strategies in both traditional and digital asset markets.
