What to Watch
Drifting from pattern
Recent correlation (+21%) is running 1.5σ away from the long-run average of -44%.
Holds across regimes
Correlation is similar when markets rise (-16%) and fall (+17%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
