Under the assumption of market neutrality, pair traders expect that the underperforming stock will eventually return to neutral performance – which means a price increase. Meanwhile, the same assumption for the overperforming stock indicates bull pennant that a price decrease should occur.

In addition to the option of manually entering trades, there are some trading programs designed to handle pairs execution. These programs are designed to simultaneously work each side for the trader, particularly for larger orders, in an attempt to hit a pre-specified price ratio. For most traders, such programs are more of a convenience than a necessity because the slippage that occurs during execution is minimal relative to the profit objective of the overall trade. To illustrate the potential profit of the pairs trade strategy, consider Stock A and Stock B, which have a high correlation of 0.95. The two stocks deviate from their historical trending correlation in the short-term, with a correlation of 0.50. A pairs trade strategy is based on the historical correlation of two securities.
Pairs trading is a truly versatile class of trading strategies that harbours enormous potential. ArbitrageLab is a collection of the landmark and most cutting edge implementations all packaged into a python library, making it perfect for investors who want to hit the ground running. The Comprehensive Introduction to Pairs Trading was created to answer the questions arising whilst building these strategies. The resampling method addresses the weakness of the walk-forward technique, by introducing the assumption that future paths can be simulated by resampling of past observations. The resampling methods can vary from deterministic (jackknife, cross-validation) to random (subsampling, bootstrap).
To distinguish profitable results from plain luck, their test included conservative estimates of transaction costs and randomly selected pairs. The best advantage of pairs trading is that the trader is completely hedged. Hedging is done in this strategy as the trader sells the overvalued security and purchases the undervalued security, thereby, limiting the chances of loss.
Some securities tend to move in the same direction, even if the percentage changes are different.

In this case, you might only want to execute it during the periods that work. You will know when to enter the trade and when not to, even as the 2 assets diverge and everyone else is entering the pairs trade. Moreover, profits and losses from these idiosyncratic stock effects might cancel out because you have exposure to many stocks. If you use the end-of-day data, you might not be able to enter at the listed prices. After a selection process has been defined, a trader must use that process to generate a list of candidate trades. If relying on manual research, the results of this inquiry constitute the list; if relying on a model, the model’s output serves as the list of candidates.

If you make 0.5% per trade (net of fees) and manage to fire 5 trades a month, you will make 2.5% a month.
