INFORMATION ADVANTAGES OF LARGE INSTITUTIONAL OWNERS

摘要

We study the relation between the percentage of outstanding shares held by a firm's largest institutional owner and the bid-ask spread on that firm's shares, a measure of information risk. We find that the greater the percentage of shares held by the largest institutional investor, the greater the bid-ask spread in share prices. In contrast, the percentage of shares held by-smaller institutional owners is related to lower bid-ask spreads. The results imply that only the largest of a firm's institutional owners-and no other institutional owner-is perceived to hold an information advantage.
