Merger Arbitrage as Diversification Strategy

Merger arbitrage is an investment style in which investors seek to buy shares of firms that are acquisition targets with the objective of realizing the difference between the amount for which the target is being acquired and the stock price of the target shortly after the acquisition is announced.

Betting on mergers is a classic hedge fund arbitrage strategy.

Are Short Covering Trades Informative?

The importance of the role played by short sellers has received increasing academic attention in recent years. Short sellers help keep market prices efficient by preventing overpricing and the formation of price bubbles in financial markets. Market efficiency is important because an efficient market allocates capital efficiently. If short sellers were inhibited from expressing their views on valuations, securities prices could become overvalued and excess capital would be allocated to those firms.
