Institutional Ownership and the Extent to which Stock Prices Reflect Future Earnings
发现机构持股比例越高，股价越能提前反映未来收益信息，说明机构投资者比个人投资者更善于利用当前信息预测未来收益。
Articles in the financial press suggest that institutional investors are overly focused on current profitability. This suggests that as institutional ownership increases, stock prices will reflect less current period information that is predictive of future period earnings. On the other hand, institutional investors are often characterized in academic research as sophisticated investors. Sophisticated investors should be better able to utilize current period information to predict future earnings compared to other owners. According to this characterization, as institutional ownership increases, stock prices should reflect more current period information that is predictive of future period earnings. Consistent with this latter view, we find that the extent to which stock prices lead earnings is positively related to the percentage of institutional ownership. This result holds after controlling for various factors that affect the relation between price and earnings. It also holds when we control for endogenous portfolio choices of institutions (e.g., institutional investors may be attracted to firms in richer information environments where stock prices tend to lead earnings). Further, a regression of stock returns on order backlog, conditional on the percentage of institutional ownership, indicates that institutional owners place more weight on order backlog compared to other owners. This is consistent with institutional owners using non-earnings information to predict future earnings. It also explains, in part, why prices lead earnings to a greater extent when there is a higher concentration of institutional owners.
