Play the stress test guessing game!

Can't wait to figure out which banks didn't perform well on the Fed's stress tests? Judging by the daily trickle of information those in the know are passing on to eager reporters, neither can anyone else.

Investors, analysts, economists and journalists are all trying to figure out which of the largest U.S. financial institutions will need to raise more capital. The Fed's explanation last week of the tests' methodology, which a lot of people had hoped would provide a glimpse at the answer key, wasn't very illuminating. That means most new information is coming from leaks. And the latest whispers say at least half a dozen banks could need more money.
