Overview
Relationship
These move together about 49% 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 follow.
The saved window keeps correlation, overlap, alignment, and freshness anchored to the same computed record.
What to Watch
Drifting from pattern
Recent correlation (+7%) is running 1.3σ away from the long-run average of +76%.
BK moves ~12 weeks before M2
Watch BK for an early read on M2.
Tighter in drawdowns
Pair moves more tightly when both fall (+37%) than when both rise (+14%) — 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.

+7% stronger than no-shift baseline
M2 shifted 12 weeks earlier. Reads: "Does Bank of New York Mellon Corporation today line up with M2 12 weeks from now?"

Baseline
+76%
No-shift correlation, matching the main time-series chart above.
Peak shift
+12 weeks
+83%
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.
