Abstract

This paper examines the trading behavior of professional investors around 2,130 mergers announced between 1994 and 2000. We find considerable support for the existence of price pressure around mergers caused by uniformed shifts in excess demand, but that these effects are fairly short-lived, consistent with the notion that short-run demand curves for stocks are not perfectly elastic. We estimate that roughly one half of the negative announcement period stock price reaction for acquirers in stock-financed mergers reflects downward price pressure caused by merger arbitrage short selling.
