Arbitrage

Definition of 'Arbitrage'


The simultaneous purchase and sale of an asset in order to profit from a difference in the price. It is a trade that profits by exploiting price differences of identical or similar financial instruments, on different markets or in different forms. Arbitrage exists as a result of market inefficiencies; it provides a mechanism to ensure prices do not deviate substantially from fair value for long periods of time.

Any inefficient pricing setups are usually acted upon quickly and the opportunity is often eliminated in a matter of seconds.
