The Economist on the volatile markets

This week, The Economist tries to explain the credit crunch, the subprime mortgage problem and the volatile stock market -- but fails. The Economist seems to flail about looking for an explanation without finding one.

Probably no one can explain because there isn't an explanation. Three weeks ago everyone was fat, dumb and happy. Now, everyone is worried. Not much has changed in three weeks, only the perception of events.
