This May, Dimon, one of the few bankers who continues to outspokenly support the "bigger is better" banking model, was forced to eat crow when his company lost an estimated $6.2 billion (and counting) because of Bruno Iksil, aka "the London Whale," a trader in JPMorgan's London office. Soon afterward, Dimon found himself justifying his bank in the media -- initially with humility and later with more than a hint of pique. By August, he was telling reporters, notably New York Magazine's Jessica Pressler, that part of the reason his company was able to survive its vertiginous loss was because it was so big. After initially dismissing Iksil's losing bets as a "tempest in a teapot," he later backtracked, but continued to point out that "We didn't even lose money this quarter. We earned $5 billion. The analysts estimate us having a record year."
