Much noise has been made about David Einhorn's presentation of "more than a hundred" pages on St. Joe at the Value Investor Conference from earlier this week. What few however seem to know, is that this is merely round two in what is at least a three year ongoing vendetta between the Greenlighter and the Florida real estate company. On May 23, 2007 Einhorn gave what is essentially an identical presentation to the Ira Sohn conference held at the Lincoln Center. In other words, to say that this is a new idea for the hedge fund manager is certainly a stretch. Below are the full notes that Einhorn presented back then. Contrast these to today (you can read the full presentation at Market Folly). In essence the only thing that has changed is the price target: in 2007 Einhorn saw a fair value of JOE of $15, when the stock was $53. This time, when the stock was $25, he values it anywhere between $0 and $10. Could he eventually be proven right? Who knows: after all that's why he gets paid the big bucks, and has had some great calls in the past. However, his long matched calls at the 2007 Ira Sohn conference are certainly not among them. At the time, Einhorn was a fan of Helix Energy Solutions (HLX), back when the stock was $40, and now is $10, and Natixis (KN.FP) which was €13 and now is €4, both underperforming his short call materially in the past 3.5 years. A long HLX (or KN.fp)/short JOE pair trade has certainly cost anyone who put it on a pretty penny. So, as always, buyer beware. Just because a star hedge fund manager likes or does not like something, does not make it a slam dunk.
