Tuesday, October 9, 2007 started as a nice day in New York City. A lovely early fall day, with the temperature still a balmy 80° at 2:00 in the morning. By evening, though, the temperature had dropped twenty degrees, the clouds had rolled in, there was thunder and rain. As with the weather, there were some hints of trouble here and there on Wall Street. But all in all, things could not have seemed better. Little did we know, the stormy end of 10/9/07 signaled a very large bubble that had just popped.
