FDX FedEx Corp

Shares of manufacturing and transportation companies were more or less flat as traders hedged their bets on the sustainability of the U.S. recovery.

CalAmp Corp. (CAMP) slid after the maker of radio communication equipment posted third-quarter profit shy of investor expectations. Still, contracts with construction-equipment maker Caterpillar Inc. (CAT) may help CalAmp rebound, said analysts at brokerage Canaccord.

UPS Inc. (UPS) and FedEx Corp. (FDX) said they have capped delivery guarantees this year after fears a late surge in orders would cause a repeat of glitches on delivery dates that the shippers experienced during last year's holiday season.
