Connected Stocks

MIGUEL ANTON and CHRISTOPHER POLK ´ ∗

ABSTRACT

We connect stocks through their common active mutual fund owners. We show that the

degree of shared ownership forecasts cross-sectional variation in return correlation,

controlling for exposure to systematic return factors, style and sector similarity, and

many other pair characteristics. We argue that shared ownership causes this excess

comovement based on evidence from a natural experiment—the 2003 mutual fund

trading scandal. These results motivate a novel cross-stock-reversal trading strategy

exploiting information contained in ownership connections. We show that long-short

hedge fund index returns covary negatively with this strategy, suggesting these funds

may exacerbate this excess comovement.
