Interesting David Einhorn article in the WSJ

A good read:
The Wall Street Journal reviewed the performance of 22 stocks after they were mentioned by Mr. Einhorn in television interviews, investor conferences, other public events and letters to Greenlight investors. The nine companies where analysts and investors saw his comments as negative fell by a median of 4.9% on the same day, the analysis shows. Thirty days later, the median decline was 13%.
