Colin Lokey, also known as "Tyler Durden," is breaking the first rule of Fight Club: You do not talk about Fight Club. He's also breaking the second rule of Fight Club. (See the first rule.)

After more than a year writing for the financial website Zero Hedge under the nom de doom of the cult classic's anarchic hero, Lokey's going public. In doing so, he's answering a question that has bedeviled Wall Street since the site sprang up seven years ago: Just who is Tyler Durden, anyway?

The answer, it turns out, is three people. Following an acrimonious departure this month, in which two-thirds of the trio traded allegations of hypocrisy and mental instability, Lokey, 32, decided to unmask himself and his fellow Durdens.

Lokey said the other two men are Daniel Ivandjiiski, 37, the Bulgarian-born former analyst long reputed to be behind the site, and Tim Backshall, 45, a well-known credit derivatives strategist. (Bloomberg LP competes with Zero Hedge in providing financial news and information.)
