You deserve to lose lots of money by that logic.
"I lost half my money, so I am going to sell while the stock market IS AT ITS LOWEST it has been in a decade."
You should be BUYING things right now....not taking even MORE losses on things you purchased (unless you see them going to $0, because it is true you can lose it all).
I just don't understand this idea at all. The market will bounce back, who knows when, but you aren't 60, why pull it out now?
