The psychology that can lead investors to make bad financial decisions

Say you buy shares in a company. The price climbs and months later you sell for a healthy profit. Ask why it worked, and the answer is often some version of "I made a good call." Now imagine the trade had lost money instead. Would you be as quick to blame your own judgment? Many of us wouldn't. We may point to bad timing, a jittery market, anything but ourselves.
