Mean Reversion Risk

Mean Reversion Risk is the danger that an asset price, which has deviated significantly from its historical average or fair value, will fail to return to that average within a trader's time horizon. In options trading, this risk is amplified because derivative contracts have fixed expiration dates, meaning the timing of the reversion is as critical as the direction.

If a crypto asset enters a new structural paradigm, such as a fundamental change in tokenomics or network utility, the old mean may no longer be relevant, rendering mean reversion strategies obsolete. Traders often use Bollinger Bands or moving averages to bet on a return to the mean, but they may face liquidation if the price enters a new trend phase instead.

This risk highlights the limitation of purely statistical models in markets driven by exogenous shocks. Understanding this requires analyzing whether a price move is noise or a permanent structural shift.
