What to Watch
Unusual right now
Recent correlation (+89%) is 3.4σ from the long-run average of +99% — pair is behaving differently than usual.
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.
