These move in the same direction about 65% of the time
Their swing sizes loosely line up (~19% of the pattern is shared).
Strong enough to use as a signal — check the stability and regime notes below before relying on it.
Both lines start at the same point — easy to compare when growth rates are similar.
What to Watch
Unusual right now
Recently tighter than usual — the pair is behaving differently than its long-run pattern.
Tighter in drawdowns
The relationship is stronger when both prices are falling than when both are rising — typical risk-off behaviour.
Rock solid
The relationship barely changes from period to period — treat it as a reliable signal.

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.

Baseline
+44%
No-shift correlation, matching the main time-series chart above.
Peak shift
No shift
+44%
A non-zero peak suggests one series lines up better when shifted against the other.
Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
Do They Crash Together?
How these series behave when markets are rising, falling, or diverging. A correlation that holds in drawdowns is very different from one that only works in rallies.
