It turns out high mutual fund fees are not the only enemy for an investor looking for a decent return in the equity markets. The other enemy is the investor himself (or herself) who is handicapped by the tendency to chase the hot investment du jour. Consider this statistic quoted in a recent Time magazine article, attributed to Vanguard founder John Bogle:

[In] the 20 years ending in 2005, the S&P 500 index rose 11.9% annually and the average mutual fund 9.7%, but the average investor realized only a 6.9% return.

How much does trying to time the markets cost the investor? A buy-and-hold, index investor would have grown an initial investment of $1,000 into $9,142 (assuming total expenses of 0.20%). An investor in the average mutual fund would end up with $6,370 but the investor who has a motley collection of once-hot funds would only have $3,798 to show for two decades of investing. If you are keeping track, it is almost 60% less than the passive index investor.

These days investment discussions invariably turn to energy, resources and emerging markets. The chances are pretty good that these sectors will soon turn cold but investors will be predictably piling into them this upcoming RRSP season.
