Tip: Avoid performance chasing based on short-term returns

In a book entitled "Common Sense Investing", the author Jack Bogle said, "In selecting mutual funds, most fund investors seem to rely .... on exciting performance over the short term. Studies showed that over 95% of all investor dollars flow to funds rated four or five stars by Morningstar, the statistical service most broadly used by investors in evaluating fund returns".

These star ratings are based on a composite of a fund's record over the previous 3-, 5- and 10-year periods. It has a heavy bias in favor of recent short-term returns.

A study showed that a mutual fund portfolio continuously adjusted to hold only Morningstar's five-star funds earned an annual return of 6.9 percent between 1994 and 2004, nearly 40% below the 11.0 percent return on the Total Stock Market Index.

Jack Bogle selected the top 10 performers among the 851 equity funds during the "new economy market bubble of 1997 to 1999. These funds performed badly during the bursting of the bubble in 2000 to 2002. For the six year period, these funds earned a cumulate return of 13% for the full six-year period, compared to the cumulative return of 30 percent for the S&P 500.

For the shareholders of these funds, it was a disaster. While the funds achieved a net gain of 13 percent, the shareholders incurred a loss of 57 percent. Most shareholders invested in these funds when they were close to the peak and suffered the full effect of the downfall.

Jack Bogle's message is: avoid performance chasing based on short-term returns, especially during great bull markets.
