What to Watch
Holds across regimes
Correlation is similar when markets rise (+37%) and fall (+49%) — reliable in both directions.
Rock solid
Correlation barely moves across time windows — treat this as a reliable relationship.
Time Series
Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.
