These move in the same direction about 41% of the time
Their swing sizes only faintly mirror each other (~8% of the pattern is shared).
A real but noisy link — useful as context, risky as a standalone signal.
Both lines start at the same point — easy to compare when growth rates are similar.

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
-28%
No-shift correlation, matching the main time-series chart above.
Peak shift
No shift
-28%
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.
