What to Watch
Unusual right now
Recent correlation (+79%) is 2.1σ from the long-run average of -39% — pair is behaving differently than usual.
Holds across regimes
Correlation is similar when markets rise (-4%) and fall (+3%) — 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.

Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
