One who profits from the differences in price when the same, or extremely similar, security, currency, or commodity is traded on two or more markets. The arbitrageur profits by simultaneously purchasing and selling these securities to take advantage of pricing differentials (spreads) created by market conditions. See: Risk arbitrage, convertible arbitrage, index arbitrage, and international arbitrage.
A trader who practices arbitrage. That is, an arbitrageur attempts to profit from inefficiencies in price by making transactions that offset each other. For example, one may buy a security at a low price, and, within a few seconds, re-sell it to a willing buyer at a higher price. Arbitrageurs can keep prices relatively stable as markets attempt to resist their attempts at price exploitation. They often use computer programs because their transactions can be complex and occur in rapid succession.
One who engages in arbitrage. Also called arb.
