What to Watch
Drifting from pattern
Recent correlation (-49%) is running 1.4σ away from the long-run average of -91%.
Holds across regimes
Correlation is similar when markets rise (+5%) and fall (-2%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
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.
