OFFICE DEPOT UP: The office supply chain soared 81 cents, or 19 percent, to $4.97 after reporting adjusted profits for the first quarter twice as high as analysts had expected.

INSURER WOES: American International Group fell $1.24, or 2 percent, to $51.50. The company reported revenue that was below what investors were expecting.
HOME PRICES: U.S. home prices rose at a slightly slower pace in the 12 months that ended in March, according to data provider CoreLogic. It's another sign that weak sales, caused in part by rising mortgage rates, have begun to restrain the housing market's sharp price gains.
ANOTHER BIG PHARMA DEAL: Merck fell $1.14, or 2 percent, to $57.48 after the drug company agreed to sell its non-prescription medicine and consumer-care business to Germany's Bayer for $14.2 billion. Products in that business include Claritin allergy pills, Coppertone sunscreen and Dr. Scholl's footcare products.
MORE EXPORTS: The U.S. trade deficit narrowed in March as exports rose to the second highest level on record, led by gains in sales of aircraft, autos and farm goods. The deficit declined to $40.4 billion, down 3.6 percent from a revised February imbalance of $41.9 billion, the Commerce Department reported. The February deficit had been the biggest trade gap in five months.
