What to Watch
Drifting from pattern
Recent correlation (+72%) is running 1.8σ away from the long-run average of -4%.
INTC moves ~6 days before DAL
Watch INTC for an early read on DAL.
Tighter in drawdowns
Pair moves more tightly when both fall (+29%) than when both rise (+7%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
Time Series
Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.
