Informed Repurchases, Information Asymmetry and the Market Response to Open Market Share Repurchases

This paper relates informed repurchases to firm information asymmetry. We propose a new measure of informed repurchases, which is based on causality tests relating repurchase information to firm returns. Our results indicate that informed repurchases show larger abnormal returns surrounding the announcement of an open market share repurchase, which suggests the market at least partially recognizes informed repurchases. This holds after controlling for conventional information asymmetry proxies, such as firm size, number of analysts following, and analyst forecast dispersion, indicating that the market is aware of repurchase specific information not captured by traditional information asymmetry proxies. Informed repurchases demonstrate larger long-term abnormal returns at one, two, and three-year windows than high traditional information asymmetry repurchases
