The beauty of pairs trading is that it can be utilized by both fundamental investors and technical analysts. The difficulty comes when prices of the two securities begin to drift apart, i.e. the spread begins to trend instead of reverting to the original mean. Dealing with such adverse situations requires strict risk management rules, which have the trader exit an unprofitable trade as soon as the original setup—a bet for reversion to the mean—has been invalidated.

A common way to model, and forecast, the spread for risk management purposes is by using autoregressive moving average models.

The advantage in terms of reaction time allows traders to take advantage of tighter spreads. The strategy monitors performance of two historically correlated securities. Option traders use calls and puts to hedge risks and exploit volatility (or the lack thereof). A call is a commitment by the writer to sell shares of a stock at a given price sometime in the future.

Technical investors will just use the price, but since the price is essentially a function of expected earnings in the future, the overall approach is the same. The reason for the deviated stock to come back to original value is itself an assumption. It is assumed that the pair will have similar business performance as in the past during the holding period of the stock. Instead of entering a trade on divergence and betting on convergence, you can enter a trade on divergence and bet that there is even more divergence.
