What caused the selloff starting at 2:30 today?
There weren't any big reports. By tomorrow morning we'll be hearing from hoards of pundits announcing that at 2:30 the big "something" caused the drop, but imho what we saw was profit taking that brought general prices merely to the lows we've been seeing for the past ten trading days. OK, we're getting market instability, but I'd be reluctant to say I was looking at a new trend direction unless we started seeing new lows.
