What to Watch
Drifting from pattern
Recent correlation (+44%) is running 1.3σ away from the long-run average of -4%.
Holds across regimes
Correlation is similar when markets rise (+14%) and fall (+29%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
