Briggs & Stratton (down $3.06 to $28.74, Charts) reported earnings that fell sharply in the wake of a mild U.S. hurricane season, and the company cut its profit forecast for the year.

Continental Airlines (down $1.36 to $42.38, Charts, Fortune 500) posted a higher-than-expected first quarter profit helped by fuller planes, higher fares and a slight decline in fuel prices.

Harley-Davidson (up $2.44 to $63.70, Charts, Fortune 500) reported better-than-expected results despite a strike at a key plant.

Altria Group (down $0.71 to $69.37, Charts, Fortune 500) posted quarterly earnings below analysts' forecasts due to weakness at its Phillip Morris USA tobacco business.

Nokia Corp. (up $0.84 to $24.71, Charts) reported a robust profit margin for the first quarter helped by buoyant emerging market demand, pushing its shares to a 12-month high.

New York Times Company (down $0.52 to $24.04, Charts) said its first-quarter profit fell 26 percent, hurt by weakness in print advertising and various charges.
