Once is Enough -- I Won't Be Making This Mistake Again in the Next Bull Market
Regardless of how often investors hear about the importance of discipline, we're all tempted to go with our gut. It happens all the time. In a bear market, it can mean sitting on the sidelines until prices fall just a little more. In a bull market, it can mean giving in to euphoria and buying a stock just because it's going up.
Nobody can predict with 100% certainty what the stock market will do. And thinking you can often causes more harm than good. If you're "right" a few times, it can set a bad precedent and give the false hope of sustainability over the long run.
But that doesn't stop us from giving in to the temptation. I can speak from experience.
