A better-than-expected earnings report from Avago Technologies (AVGO) gave a shot in the arm to chipmakers, which have been recovering from a summer sell-off. Avago said after the close Wednesday that earnings per share rose 26% from a year ago and sales rose 16%. Thursday morning, Mizuho Securities raised its price target from 165 to 175, and Topeka Capital Markets raised its price target to 153 from 130.
