One of the big benefits of professional money management is “emotional control.”
Emotional control is the ability to control one’s emotions in times of stress. Napoleon once said that “The greatest general is he who makes the fewest mistakes.” There is a similarity between war and successful investing. Both require the ability to keep a cool head at times of high stress.
There is another old saying in the investment world: “Don’t confuse brains with a Bull Market.” When the market is going up, it’s easy to assume that you are making smart investment decisions. But your decisions may have nothing to do with your success; you may simply by riding the crest of a wave.
That’s when people become overconfident.
When the market stops going up, or the next Bear Market begins, the amateur investor allows fear to dominate his thinking. The typical investor tend to sell as the stock market reached its bottom. In fact, following the market bottom in early 2009, even as the stock market began to recover, investors continued to sell stock funds. Since then the market has doubled.
Professional investors are not immune to emotion, but the good ones have developed investment models that allow them to ride through Bear Markets with moderate losses and ride the rebound up as the market recovers. It is that discipline that allows them to make fewer mistakes and, like Napoleon’s general, come out ahead.
