Money management firms are bombarding us with ads touting their latest best performing mutual fund that returned 30% last year and 20% over the past three and if you are tempted to buy based on the performance, consider the following statistic cited in The Smartest Investment Book You’ll Ever Read:

One telling study involving mutual fund investors in the United States demonstrated that the average hyperactively managed fund investor had an annualized return for the 20-year period from 1985 to 2004 of 3.7%, when the S&P 500 Index returned 13.2%. The investor would have done better with bank certificates of deposit!

The main reason for the underperformance was chasing the latest hot funds. So the next time you see the sexy performance numbers of the fund du jour and you start thinking: “That sure sounds better than the 4% I am getting from my lousy GIC. Maybe I should get in on this fund”. Resist the urge, give your head a shake and remember that chasing performance is the surest route to investment ruin.
