What to Watch
Drifting from pattern
Recent correlation (+96%) is running 1.9σ away from the long-run average of +93%.
Holds across regimes
Correlation is similar when markets rise (+62%) and fall (+58%) — 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.
