What to Watch
Drifting from pattern
Recent correlation (-8%) is running 1.5σ away from the long-run average of -86%.
Holds across regimes
Correlation is similar when markets rise (-11%) and fall (+10%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
