LinkedIn plunges 44%
LinkedIn's stock had its worst day ever. Shares cratered by as much as 44% in trading on Friday after the company reported a quarterly loss on Thursday, with guidance that was weaker than expected. It was the worst decline ever for the stock and has erased about $10 billion of the company's value. The social network for professionals said that it expected first-quarter adjusted earnings per share (EPS) of $0.55, but analysts had estimated $0.75, according to Bloomberg.
