The act of taking advantage of differences in price between markets. For example, if a stock is quoted on two different equity markets, there is the possibility of arbitrage if the quoted price (adjusted for institutional idiosyncrasies) in one market differs from the quoted price in the other. The term has been extended to refer to speculators who take positions on the correlation between two different types of instrument, assuming stability to the correlation patterns. Many funds have discovered that correlation is not as stable as it is assumed to be.
