No. 5 -- HP Breakup
For a nearly a year after his arrival, HP's (HPQ) new chief Leo Apotheker quietly assessed the PC giant's problems as he prepared a grand solution.
On Aug. 18, Apotheker made what was seen as a rash move to kill the Palm WebOS TouchPad products, explore the spinoff of the world's largest PC business, and retool the company as more of an enterprise software company.Overnight, the stock fell 23% as investors fled in the aftermath of the breakup strategy. Though the company has backpedaled on any immediate carve-out of the PC division, and has revived limited production of TouchPad tablets, there's been no atonement yet by Apotheker.
