On Marketocracy.com, investors create hypothetical online portfolios; currently, there are roughly 30,000 active users. Of the portfolios they produce, Marketocracy takes its favorites—up to 100 at a time—and uses them to select fund's actual holdings. If your model is used, you get a small piece of the action. Manager Ken Kam says the fund's team vets model portfolios thoroughly to weed out investors that are successful only by way of a fluke. "There's a lot of checking to make sure that it's not the result of one or two great stock picks over the last five years. We like to see good stock selection and good trading ability," he says.
