The fine folks at the implode-o-meter sites have been keeping track of companies that have imploded during the ongoing credit crisis.
Mortgage Lenders. 236 since late 2006.
Home builders. 22, since late 2006 (“plus 15 additional tiny implosions”)
Hedge funds. 32 since mid 2007.
Banks. Only a few so far, but we’re just warming up here. “There will be some bank failures” – Ben Bernanke, Feb. 2008.
