This means you profit if the market moves in your direction — but you also take on market risk, namely, the risk that if the price moves adversely, you lose money. The outcome of any of these situations will be dynamic and unknown, but the correlations are almost certain to change. Exiting the trade involves closing both positions once the spread returns to the average historical level. The trader profits by the convergence of the prices and the closing of the positions at favorable prices. The strategy’s success relies on the expectation that the prices of the two assets will converge over time, allowing the trader to close both positions for a profit. A key assumption in pairs trading is that two assets will maintain a historical correlation.
This investment strategy will entail buying the undervalued security while short-selling the overvalued security, all while maintaining market neutrality. Another popular approach to pairs trading is the distance-based method, which focuses on the relative price differences between two assets. In this strategy, the trader measures the distance between the two asset prices, usually by calculating the spread (difference in prices) between them.
Execution and Liquidity Risks
- Traders use statistical tools such as z-scores to determine when the spread between the two assets is unusually wide, signaling a potential opportunity to enter a trade.
- A major assumption of the strategy is that the historical price relationship will continue to hold in the future.
- Another popular approach to pairs trading is the distance-based method, which focuses on the relative price differences between two assets.
- But sometimes, two historically correlated stocks diverge and stay that way, due, perhaps, to a permanent fundamental change in one of the two companies.
This strategy works well in markets where volatility is relatively low, and asset prices tend to revert to their historical mean. The following worked example — using real market prices — is designed to explain the principles involved and illustrate a possible methodology for a simplified pairs trading strategy. Pairs trading is a strategy that tends to use statistics to identify relationships, assist in determining the direction of the relationship, and then ascertain how to execute a trade based on the data. The pairs trader attempts to capitalize on market imbalances between 2 or more financial instruments, such as stocks or funds, in anticipation of making money when the inequality is corrected.
What is pairs trading and how does it add value?
Market-neutral strategies involve long and short positions in two different securities with a positive correlation. The two offsetting positions form the basis for a hedging strategy that seeks to benefit from either a positive or negative trend. Pairs trading is a hedged strategy, meaning traders are less exposed to overall market movements.

Going back to our example, let’s say it is May 20, 2022 and we have seen the ratio increase from near the mean up to a value of 2.4. We decide to go short Anglo American and long Antofagasta, hoping the ratio will drop with time. We trade the next day, selling Anglo American at 3575 and buying Antofagasta at 1450. A value of 1 shows a perfect correlation, while a value of 0 shows no correlation.
The goal is to identify moments when their usual correlation temporarily breaks, creating a trading opportunity. As the strategy aims to minimise market risk, you are looking for your two positions to hedge each other, so you want an equal exposure with each half of the pairs trade.

Benefits and Risks of Pairs Trading
The larger the spread, the more likely it is that the prices will converge over time. To create a successful pairs trade, traders must first identify two assets that are highly correlated, meaning their prices tend to move in the same direction over time. This correlation can be measured using statistical tools such as the Pearson correlation coefficient, which quantifies the strength and direction of the relationship between the two assets.
By carefully selecting asset pairs, using statistical analysis, and applying proper risk management, traders can improve their chances of success. However, like any trading strategy, pairs trading comes with risks, including correlation breakdowns and execution challenges. Pairs trading is a powerful and flexible strategy that can be employed across various asset classes and market conditions. By exploiting the relative price movements of two correlated assets, traders can generate profits while remaining market-neutral. The strategy’s success depends on careful pair selection, sound statistical analysis, and robust risk management techniques.
- Markets don’t move in straight lines, and opportunities exist on both sides – in the companies that surprise on the upside and those that fall short of expectations.

For a pairs trader looking for an arbitrage-type convergence, that’s a lot of time between trade initiation and liquidation, considering a pairs trade requires a short stock position. Traders use statistical tools such as z-scores to determine when the spread between the two assets is unusually wide, signaling a potential opportunity to enter a trade. A z-score is calculated by taking the difference between the current spread and the mean spread and dividing it by the standard deviation of the spread. A high z-score indicates a significant deviation from the historical mean, which may suggest that the prices will soon revert to their normal relationship. Traders can use cointegration-based strategies to identify pairs of assets that will likely show mean reversion over time. The advantage of this approach is that it provides a more rigorous statistical basis for selecting asset pairs, as it considers both the correlation and the cointegration of the assets.
Trading both an underperforming and outperforming security allows investors to hedge risks and leverage historical correlations for potential gains. A pairs trade is a market-neutral trading strategy in which you buy (take a long position in) a stock or other security and sell (take a short position in) another security. The typical goal of a pairs trading strategy is to find a pair that has fallen out of its historical correlation and seek to profit as the spread between them closes back toward historical correlation levels. Pairs trading is a versatile market-neutral strategy that allows traders to profit from price discrepancies between two correlated assets while minimizing exposure to overall market trends.
