Don't Sell Stocks After the Market Crashes Down

Chris: Is there a biggest mistake that you see people make when it comes to investing? David: I would say performance chasing, buying what has gone up and selling what has gone down just doesn't work. Chris: You don't decide to buy more stock after the market goes way up; especially you don't sell stocks after they crash down.David: Losing money feels really painful in the psychology literature. The kind of rule of thumb is that a loss is twice as bad as an equal sized gain.
