David Einhorn, Whose Greenlight Is Down 5% YTD, Dumps Recently Purchased Yahoo! Stake

``Well that didn't take long. Just over two months after Einhorn's Greenlight bought a stake in Yahoo, he has now dumped the full amount. From his just issued letter to clients: "The Partnership bought Yahoo! (YHOO) earlier this year based on a sum of the parts analysis, which included putting substantial value on its Chinese assets. Shortly after the purchase, the value of the Chinese assets came into doubt as the CEO of the Chinese unit hived-off a valuable subsidiary into a corporation that he personally controls. From there, the finger pointing started in every direction.''
