Strong positive
Strong enough to use as a signal — read the stability and regime notes below before relying on it.

What to Watch
Holds across regimes
Correlation is similar when markets rise (+42%) and fall (+32%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
