FedEx Corp. shares fell after the parcel delivery company lowered its full-year guidance for a third consecutive quarter, citing inflation and uncertain demand for shipments.

An economic bellwether because of its broad exposure to the global economy, FedEx said its latest outlook assumes the global economic, political and trade environment doesn’t worsen any further.

The delivery giant's latest downward guidance revision could be a concern for both FedEx stock itself and the U.S. economy overall.
