Andrew Lahde's Lahde Capital, a small California-based hedge fund, has done just that by making big bets against subprime in 2007. A quick glance over the recent headlines indicates that that has been a very, very, very profitable bet.
Given that he had the conviction to go short with leverage, this is probably a guy worth paying attention to. The Financial Times has some quotes from his letter to shareholders, where he announces a return of a capital, saying that "The risk/return characteristics are far less attractive than in the past." Here's some other stuff from the letter:

Mr. Lahde has extensive experience in company and industry analysis, particularly in the telecom and business
