Institutional Investors and Information Asymmetry: An Event Study of Self-Tender Offers



Our research compares the asymmetric information costs of firms with low levels of institutional ownership to those with high levels. We use self-tender offers as an information event. Our results show that higher institutional ownership, particularly a higher number of institutional investors, is associated with a lower degree of informed trading. These results persist even after we control for differences in trading activity among our sample firms.
