In corporate news, shares of FedEx fell more than 3% after the package delivery giant lowered its full-year earnings outlook to between $6.20 and $6.60 a share, down from its prior estimate of $6.90 to $7.40 a share, as the company continues to feel the pain of the sluggish global economy. The company estimates earnings of $1.30 to $1.45 a share in the current quarter, down from $1.57 a share a year earlier. FedEx posted fiscal first-quarter earnings of $1.45 a share versus the $1.40 a share predicted by Wall Street. "Earnings for the first quarter were below our expectations as weak global economic conditions dampened revenue growth, drove a shift by our customers to our deferred services and outpaced our near-term ability to reduce FedEx Express operating costs to match demand levels," Alan Graf, the company's chief financial officer, said in a press release.
