Backtesting Obsolescence

Backtesting obsolescence occurs when historical performance data loses its predictive power for future market behavior. A strategy might show exceptional returns on past data but fail to account for structural shifts in the market, such as changes in volatility regimes or regulatory environments.

In crypto, where protocols and tokenomics evolve rapidly, past performance is rarely a reliable indicator of future results. When a strategy relies on correlations that no longer exist, the backtest becomes a misleading metric.

This forces quantitative analysts to constantly update their models with fresh data and account for non-stationary market variables.
