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
Drifting from pattern
Recent correlation (+95%) is running 1.0σ away from the long-run average of +70%.
Holds across regimes
Correlation is similar when markets rise (+14%) and fall (+1%) — reliable in both directions.
Flaky
Correlation swings widely across time windows — careful using this as a point estimate.
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.
