You'll always have people who panic when it comes to money.
Example: all the people who bailed out on their stock options at $12, thinking that AMR was going to follow DAL and CAL into the courthouse. Had they waited until today, when it closed at $19.32, they'd have walked away with double their money...
Then again, I don't have a huge lump sum to look forward to, so I guess I'm a little more of a risk taker.
