Lennar—The home builder reported fiscal first quarter profit of 35 cents per share, seven cents above estimates, with revenue above consensus as well. Lennar sold more homes at higher prices, although it said it is too soon to predict how well the spring home selling season will go.
ConAgra–The food producer reported fiscal third quarter profit of 62 cents per share, excluding certain items, beating estimates by two cents. ConAgra said it is dealing with "operating challenges" that have impacted earnings, but that it is encouraged by some "pockets of strength."
Under Armour–Sterne Agee cut its rating on the athletic apparel maker's shares to "neutral" from "buy", after a year-to-date gain of 40 percent. However, the firm said its view of Under Armour's long term growth prospects remains intact.
