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.

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.

You should consider whether you understand how CFDs work, and whether you can afford to take the high risk of losing your money.

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.

Works in All Market Conditions

For example, consider two companies in the same industry, like Coca-Cola (KO) and Pepsi (PEP). Historically, their stock prices tend to move similarly because they operate in the same sector, face similar market conditions, and compete for the same customers. Yes, but it requires a solid understanding of correlations, statistical analysis, and risk management. Beginners should start with demo accounts and backtesting before trading with real capital.

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.

• However, short-term price fluctuations can create temporary imbalances between them.
• The classic pairs trade can be applied to a variety of asset pairs, such as stocks in the same industry, ETFs that track similar indices, or commodities like gold and silver.
• Unlike directional trades, pairs trading is market-neutral, meaning it seeks to generate returns regardless of whether the broader market rises or falls.
• Pairs trading is also widely used in the forex market, where traders take advantage of price differences between two highly correlated currency pairs.

To implement a cointegration-based strategy, traders typically use tests like the Engle-Granger two-step method or the Johansen test to identify cointegrated pairs. Cultural shifts and management changes at Woolworths have weighed on performance, while Coles strengthened its market share. Over the past 12 months, Woolworths has ceded earnings momentum and market premium to Coles. This pair trade generated an impressive 30% return, underscoring the power of relative positioning. Because traders hold both a long and a short position, broad market fluctuations have a smaller impact compared to trading a single asset.

What is the best risk-to-reward ratio in pairs trading?

We do not provide financial advice, offer or make solicitation of any investments. Trading and investing in financial instruments comes with a high degree of risk and you can lose money. You should only engage in any such activity only if you are fully aware of the relevant risks. For example, if two stocks are historically correlated and one stock drops significantly while the other rises, a trader might expect the prices to revert to their normal relationship. The entry point would be when the spread reaches a point that is significantly wider than usual.

Step 4: Monitoring and Closing the Trade

The other option is to initiate a trailing stop loss level to lock in at least a portion of the profit. The trader will develop a feel for which of these options more suits their particular style, and may make different decisions for different pairs at different times. Pairs work is based on a correlation between 2 (or more) stocks, sectors, indexes, or other financial instruments. Generally, the service road follows the highway closely but terrain or development will sometimes cause the 2 to diverge. The area between the highway and the service road can be thought of as the spread—the measured distance between the 2 objects traveling together. The pairs trader attempts to measure the spread with statistics in an effort to find a tradable relationship of inequality opportunities.

How to Manage Risk as a Trader or Investor

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.

• Yes, but it requires a solid understanding of correlations, statistical analysis, and risk management.
• There is a risk, therefore, that something fundamentally changes to affect the pricing of one stock and not the other, or something happens that affects them both in a different way.
• The successful execution of each of the steps is a critical element in the process of becoming a profitable pairs trader.
• 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 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.

However, correlations can break down due to fundamental shifts, economic events, or industry changes, making the trade invalid. In a nutshell, pairs trading works by betting that 2 or more securities will diverge or converge in price. The trader bets that a $50 stock and a $55 stock, for instance, will either have a larger or smaller spread ($5 in this case) when the trade is closed. Divergence traders will like to see the spread increase while convergence traders will prefer to see the spread decrease. It’s worth noting, however, that it took three months for this trade to come to fruition.

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.

By focusing on relative value rather than absolute direction, pairs trades help amplify alpha, improve portfolio diversification, and reduce exposure to macro-driven volatility. Unlike directional trades, pairs trading is market-neutral, meaning it seeks to generate returns regardless of whether the broader market rises or falls. This makes it particularly valuable in volatile or uncertain environments or by allowing the portfolio manager to add alpha when the market is directionless, volatile or even falling.
