Using merger announcements and applying methods from computational linguistics we find strong evidence that stock prices underreact to information in financial media. A one standard deviation increase in the media-implied probability of merger completion increases the subsequent 12-day return of...

A one standard deviation increase in the media-implied probability of merger completion increases the subsequent 12-day return of...

We evaluate the over-valuation hypothesis and merger arbitrage price pressure hypothesis as potential explanations for the observed negative returns to stock acquirers around merger announcement. Using daily shorting flow data, we show that the majority of the negative announcement returns can...

Information effects hypothesis and price pressure hypothesis are two major theories when explaining negative market reaction on acquiring firms' stock prices during stock financed mergers and acquisitions. However, it is difficult to hold the information effects constant and to distinguish...

Research argues that short sellers are informed investors as current short selling relates inversely with future returns. However, empirical results have yet to determine whether short sellers trade on private information before, say, an upcoming negative new. This paper takes a step in this...

Our study investigates the true valuation motive for increasing share repurchases. To do so, we analyze the contemporaneous trading dynamics between short sellers, institutional investors and the firm itself around the actual share repurchases. We regress quarterly changes in share repurchases...
