Repeat after us: There is no goof-proof method of playing the stock market. But if we don’t know what to do all by our lonesomes, maybe we can figure it out together.

That’s the logic behind the Marketocracy Masters 100 mutual fund (ticker: MOFQX). Each month, fund manager Ken Kam selects 100 hypothetical portfolios from among thousands submitted by ordinary-Joe investors. He (and his software) decide which stocks are favored by the investors with the hottest records. Then he shifts the fund’s dollars to reflect those picks.

According to the fund’s website, the Masters 100 has beaten the S&P 500 index in 10 of 14 quarters since its 2001 debut. As always, your mileage may vary. For more information, go to www.marketocracy.com. — C.T.
