A real but noisy link — useful as context, risky as a standalone signal.
FedEx pioneered overnight delivery in 1973 and remains the world's largest express package provider. In fiscal 2025, the firm's Federal Express segment—which houses the core package delivery operations—made up 86% of total revenue, with 10% coming from FedEx Freight, its asset-based less-than-truckload shipping segment. The remainder came from other services, including FedEx Office, which provides document production/shipping, and FedEx Logistics, which provides global forwarding. FedEx acquired Dutch parcel delivery firm TNT Express in 2016, boosting its presence across Europe. TNT was previously the fourth-largest global parcel delivery provider.

What to Watch
Holds across regimes
Correlation is similar when markets rise (+9%) and fall (-6%) — reliable in both directions.
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.
