What is Merger Arbitrage?

Merger arbitrage, otherwise known as risk arbitrage, is a lesser-known investment strategy among the general investing public. This strategy seeks to profit from the uncertainty that occurs during announced corporate takeovers or mergers.

It is a type of event-driven investing that aims to capitalize on differences between stock prices during the period between when an acquisition is announced and when it is formally completed. Investors who employ merger arbitrage strategies are known as arbitrageurs.


How Does a Merger Arbitrage Work?

In a typical merger, the acquirer is often required to purchase the target company’s shares at a higher-than-market price — this is called a control premium. The announcement of the merger at a higher price tends to drive up the price of the target’s shares, allowing investors to profit from the difference.

Investors can either benefit from the announcement or the successful completion of the merger, depending on the time of investment. If the investor already owns shares prior to the announcement, they can benefit from the increase in prices on the day of the announcement. If the investor chooses to purchase the target’s shares after the announcement, their gains depend on the arbitrage spread. The arbitrage spread refers to the difference between the acquisition price of the shares and the market price at the time of investment. The larger the spread, the higher the potential reward for the investor.



What Factors Can Affect a Merger?

Although a vast majority of mergers and acquisitions successfully close, there is always a chance that one will not. The greater the potential issues, the wider the spread tends to be, and thus the greater potential profit for the merger arbitrage investor. Four main things can affect a merger deal:

What’s The Difference Between Active Arbitrage vs. Passive Arbitrage?

Active arbitrage refers to a situation where the arbitrageur holds enough stock in the target company to influence the outcome of the merger.

Passive arbitrage is when arbitrageurs are not in the position to influence the merger – they make investments based on the probability of success (and the degree of hostility) and size up their investments when this probability increases.


How Does Merger Arbitrage Work as an Investment Strategy?

Merger arbitrage is an alternative investment strategy offering traditional stock and bond investors the potential to create a more efficient and diversified portfolio, targeting both steady gains and minimization of drawdowns through up and down markets alike.

The goal of a merger arbitrage strategy is to put together a diversified portfolio of arbitrage trades where each trade offers these three features:

  1. Attractive annualized return above one’s cost of capital
  2. Market-implied probability of success below one’s estimate
  3. Idiosyncratic return expectation with low correlation to other trades
