Does intelligence equate with investment management success?
What might it take to succeed in investing? Intelligence alone? You have to be intelligent to get into Mensa. They only accept applicants with IQs that place them in the top 2 percent of the population. One might expect that if Mensa members formed an investment club, their returns would exceed market averages, or at least match them. In actuality, between 1986 and 2001, while the S&P 500 was returning a robust 15.3% annually, the Mensa Investment Club had average returns of 2.5% per year.
How did these geniuses and near geniuses manage such poor results in such a strong market? Their basic problem was a lack of discipline. Instead of using their intellects to determine a sound investment approach and sticking with it, they got sidetracked into exploring trendy new tools and theories of how to predict market trends. When one strategy didn’t work they tried another. They made frequent trades, thus increasing their transaction costs. In short, they provided a perfect example of Warren Buffett’s comment: “Investing is not a game where the guy with the 160 IQ beats the guy with the 130 IQ.” Common sense and discipline will beat erratic genius every time.
