Tunku Varadarajan at Forbes has a pretty clever piece titled "The Financial Crisis From A-Z". Here are a few of the items that tickled my fancy: C is for Credit Default Swaps , defined for me by a Wall Street watcher as: Risk whatever you want, and we insure it; risk too much, taxpayers insure it. L is for leverage (a means of maximizing your losses), liar loans, Lehman (pronounced "lemon")--and the losses/liabilities that unite them all. M is for where it all started: the mortgage (which, aptly, means death-pledge). Like the dog, it comes in a variety of breeds, "sub-prime" being a cross between a pit bull and a chihuahua. Q is for quants, who forgot that, every so often, past performance is no indicator of anything at all. S is for securitization , the process by which one passes off cat food as caviar. The other 21 letters are pretty good too. Read the whole thing here . HT: The Big Picture .
