Correlation Decay Training

Definition

Correlation decay training refers to a quantitative methodology employed in digital asset markets to account for the systematic breakdown of lead-lag relationships between crypto-assets and traditional derivatives. Analysts utilize this process to refine predictive models by de-weighting historical correlation inputs that lose relevance during periods of extreme market regime shifts. By minimizing reliance on stale inter-asset dependencies, traders improve the accuracy of cross-margin hedging and portfolio variance estimates.
