Realized Volatility Risk

Realized volatility risk is the uncertainty associated with the actual historical price fluctuations of an asset over a specific period. Unlike implied volatility, which is a forward-looking estimate derived from option prices, realized volatility is calculated from past price data.

Traders face this risk when their hedging strategy relies on assumptions about future volatility that may not materialize. If realized volatility is higher than expected, a delta-neutral portfolio may suffer losses due to the costs of frequent rebalancing.

Conversely, if it is lower, the income generated from the option premium may be insufficient to cover the hedging costs. In crypto, where volatility is notoriously high and unpredictable, this risk is a primary concern for any options strategy.

Effective management involves stress testing and scenario analysis to understand how different volatility regimes impact the portfolio. It is the gap between expected and actual market behavior.
