The past few weeks have shown investor irrationality at its worst. If people didn't need their money immediately and bailed from the market, they're idiots.
I agree. Short of the market collapsing completely (or the specific companies you've invested in going bankrupt), "losses" are only on paper and only become realized if you sell.
Great article by Warren Buffet in the New York Times. http://www.nytimes.com/2008/10/17/opinion/17buffett.html
The market has been a day traders dream. It's a great article and Buffet is right, now is the time to buy. I've been day trading Visa (V) and RIMM the last couple of weeks and I've taken a position on the telecomm stocks. They pay a nice dividend.
