When bias costs billions

Your fund manager may be “too much of a homebody,” said Ian Salisbury in SmartMoney.com, and it could be hurting your portfolio. Professional investment managers collect billions in fees to scour the market for bargains that ordinary investors would never find on their own. But a recent study from Indiana University’s Kelley School of Business suggests that “portfolio managers overweight companies based in the state where they grew up by 12 percent on average.” Given the size of the mutual fund industry, this “hometown bias” accounts for about $31 billion in investments each year. The bias appears to be stronger with younger investment managers, “suggesting the quirk may be tied to experience.” And it poses a risk to your portfolio since companies in the same state tend to be affected by similar business trends. You could be “too concentrated in one area of the economy,” said study co-author Scott Yonker.
