More than 1,000 hedge fund managers gathered at Lincoln Center today for the Ira W. Sohn Investment Research Conference, an event that raises money for charity as well as gives other members of the industry a chance to gleam investment recommendations from some of the brightest financial geniuses around. (Those who paid the $3,000-per-person fee this year were treated to talks by the likes of Jim Chanos, Mark Kingdon, Stephen Mandel, Peter Schiff, and Peter Thiel.) Last year's conference was a particularly dramatic affair. David Einhorn, the founder of Greenlight Capital, used the event as an opportunity to explain why Lehman Brothers was headed off a cliff. Those who heeded Einhorn's advice did well for themselves, of course: The bank went bust just four months later. Einhorn spoke at the annual confab once again today, although it's too soon to know if the poker-loving hedge fund manager took aim at another financial firm this time around. In the meantime, though, Einhorn's lawyers seem to have done just that. They've been busy trying to crush the other Greenlight Capital.
