Mean Reversion Failure

Mean reversion failure occurs when an asset price, which is expected to return to its historical average, instead trends indefinitely or moves to a new, higher or lower equilibrium level. Many trading strategies are built on the assumption that extreme price deviations are temporary and will correct themselves.

However, in non-stationary markets, a price movement might represent a fundamental shift in value rather than a transient deviation. In cryptocurrency, this often happens during bull runs or prolonged market crashes where sentiment completely detaches from historical valuations.

Relying on mean reversion in such an environment can lead to traders consistently doubling down on losing positions, eventually resulting in liquidation. It is a critical risk for arbitrageurs and liquidity providers who bet on price convergence.

Understanding the difference between a mean-reverting process and a random walk or trending process is essential for survival.
