It's always good to be honest with oneself in investing. By taking a hard look at past investment decisions and evaluating why you were either right or wrong, you make yourself a better investor. In fact, Warren Buffett once said, "Post-mortems prove useful for hospitals and football teams; why not for businesses and investors?"
In that light, any money lost -- or gains missed -- can be written off as the price of a valuable investing education.
One stock I missed out on is Zoom Video Communications (NASDAQ: ZM). In fact, I went so far to call it a "bubble" back in late March during the depths of the downturn. A few months out, and that appears to have been the wrong call as the stock has rallied another 85% since that time.
