These move opposite each other about 65% of the time
Their swing sizes only faintly mirror each other (~1% of the pattern is shared).
A faint pattern — interesting as colour, not strong enough to act on alone.
Both lines start at the same point — easy to compare when growth rates are similar.
What to Watch
Slipping tighter
The recent pattern is tighter than its long-run baseline — keep an eye on whether this sticks.
Holds in both up and down markets
The relationship is similar whether prices are rising or falling — reliable in both directions.
Swings around
Their relationship swings around — sometimes tight, sometimes loose. Don't trust a single snapshot.

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
-9%
No-shift correlation, matching the main time-series chart above.
Peak shift
No shift
-9%
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.
