Invest Skeptically

Chuck Jaffe at MarketWatch writes, Dancing with the stars, and warns mutual fund investors to take the Morningstar tools for what they are. The two examples he cites as misused/misinterpreted tools are the star rating system and the style box description.

His conclusion: “Use Morningstar’s tools as intended — as helpers, and not decision-makers — and you can get the best of the research, without sinking to the lowest common denominator level that makes the fund world go batty.”
