Risk Arbitrage

Definition of 'Risk Arbitrage'


A broad definition for three types of arbitrage that contain an element of risk:

1) Merger and acquisition arbitrage - The simultaneous purchase of stock in a company being acquired and the sale (or short sale) of stock in the acquiring company.

2) Liquidation arbitrage - The exploitation of a difference between a company's current value and its estimated liquidation value.

3) Pairs trading - The exploitation of a difference between two very similar companies in the same industry that have historically been highly correlated. When the two company's values diverge to a historically high level you can take an offsetting position in each (e.g. go long in one and short the other) because, as history has shown, they will inevitable come to be similarly valued.

Investopedia explains 'Risk Arbitrage'


In theory true arbitrage is riskless, however, the world in which we operate offers very few of these opportunities. Despite these forms of arbitrage being somewhat risky, they are still relatively low-risk trading strategies which money managers (mainly hedge fund managers) and retail investors alike can employ.
