#TradingPairs101

A pairs trade strategy is based on the historical correlation of two securities. The securities in a pairs trade must have a high positive correlation, which is the primary driver behind the strategy’s profits. A pairs trade strategy is best deployed when a trader identifies a correlation discrepancy. Relying on the historical notion that the two securities will maintain a specified correlation, the pairs trade can be deployed when this correlation falters.

When pairs from the trade eventually deviate—as long as an investor is using a pairs trade strategy—they would seek to take a dollar matched the long position in the underperforming security and sell short the outperforming security. If the securities return to their historical correlation, a profit is made from the convergence of the prices.
