Overview
Relationship
These move opposite each other about 48% of the time
Strong enough to use as a signal — read the stability and regime notes below before relying on it.
Read
When one moves up, the other tends to move down.
The saved window keeps correlation, overlap, alignment, and freshness anchored to the same computed record.
What to Watch
Tighter in drawdowns
Pair moves more tightly when both fall (-31%) than when both rise (-9%) — typical risk-off behaviour.
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.

No shift — both series at their actual dates.

Baseline
-88%
No-shift correlation, matching the main time-series chart above.
Peak shift
No shift
-88%
A non-zero peak suggests one series lines up better when shifted against the other.
Deep Dive
Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
