Warren Buffett, as he always has, looks askance at Wall Street shenanigans, otherwise know as derivitives.
"You can't turn a financial toad into a prince by securitizing it," he said at a fundraiser in San Francisco for Senator Clinton, Tuesday, December 12. Mr. Buffett said that even after scrutinizing funds that package up mortgages, he found them hard to properly evaluate. (But to quote him from an earlier meeting, you don't have to know a person's exact weight to tell that person over 300 person is over-weight)
"Wall Street started believing its own PR on this - they started holding this stuff themselves, maybe because they couldn't sell it. It worked wonderfully until it didn't work at all."
