Not many would admit that here, however; market likely to be gapped down on the open monday morning and go back up so don't panic. (At least that's what S&P generally does last 10 years).
Two weeks from now I will experience this first hand from Europe. I'm taking my camera and maybe get some good shots of the lemmings rioting when ATM empty out. Plan ahead...
Back in '87 when the DOW "crashed" 500 points in one day, this nice young couple (neighbor's child) were so freaked out they liquidated because they needed that money for a down payment on a house. They couldn't be disuaded and were even more devasted when that turned out to be the bottom.
