What to Watch
Unusual right now
Recent correlation (+6%) is 2.1σ from the long-run average of -70% — pair is behaving differently than usual.
Holds across regimes
Correlation is similar when markets rise (+4%) and fall (+23%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
