What to Watch
Drifting from pattern
Recent correlation (+42%) is running 2.0σ away from the long-run average of +94%.
Holds across regimes
Correlation is similar when markets rise (+22%) and fall (+31%) — reliable in both directions.
Flaky
Correlation swings widely across time windows — careful using this as a point estimate.
Time Series
