What to Watch
Unusual right now
Recent correlation (-64%) is 2.9σ from the long-run average of +40% — pair is behaving differently than usual.
Holds across regimes
Correlation is similar when markets rise (+14%) and fall (+31%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
