What to Watch
Drifting from pattern
Recent correlation (+35%) is running 2.0σ away from the long-run average of +89%.
Holds across regimes
Correlation is similar when markets rise (+45%) and fall (+59%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
