Second, while historical trends can be accurate, past prices are not always indicative of future trends. Requiring only a correlation of 0.80 can also decrease the likelihood of the expected outcome. Pairs trading is a popular strategy, but like all strategies it is not without risks and it is not successful all the time. As with all strategies, the most important element is risk management. No investor or trader knows how a trade will turn out, and must always guard against the possibility of losses. By following the risk management rule mentioned above, investors and traders can help limit the downside of any unsuccessful pairs trade.
- The key driver of this strategy could be that the stocks participating in the same should necessarily have a higher rate of positive correlation.
- A pairs trade strategy is best deployed when a trader identifies a correlation discrepancy.
- Price relationships between instruments are always changing and can also be impacted by higher level macroeconomic factors.

What is Pairs Trading?
As an illustration, you might expect adverse changes in UK financial regulations to negatively affect both, or a pickup in demand for banking services to boost both. TWP makes no guarantee or promise of any kind, express or implied, that anyone will profit from or avoid losses from using information disseminated through TWP. A combined approach using both methods strengthens trade decisions by validating statistical signals with fundamental indicators. Stop loss is defined for scenarios when the expected outcome does not occur. For instance, if we chose entry signals at 2-sigma, we are expecting that the spread will revert back to the mean from this threshold.
However, a man walking his dog is an example of correlated movement. The dog may wander away from the man, but it will eventually come back. The man and his dog are correlated, and the times when the dog moves away from the man are examples of the ratio between two markets becoming stretched.

The higher the value, the stronger the positive correlation, with two markets moving in the same direction for a large amount of time. A negative reading indicates that the two markets are moving negatively, in the opposite direction, while a reading of 0 shows that there is no correlation in the price movement of the two markets. Pairs trading is a strategy that involves using two positions, one short and one long, on two markets with high correlation. It can be used across equities, indices, FX or commodities, or any combination of markets.

Decorrelation: The big pairs trading risk (and opportunity)
In the futures market, “mini” contracts—smaller-sized contracts that represent a fraction of the value of the full-size position—enable smaller investors to trade in futures. One is that the pairs trade relies on a high statistical correlation between two securities. Most pairs trades will require a correlation of 0.80, which can be challenging to identify.
- Now, both ‘a’ and ‘b’ increase in such a way that the value of the spread decreases.
- This strategy is very common for hedge funds, institutional investors, and experienced traders in generating profit across different market conditions.
- For instance, a stock might move 1% a day on average, while a cryptocurrency coin moves 5% a day on average.
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. “Quants” is Wall Street’s name for market researchers who use quantitative analysis to develop profitable trading strategies. In short, a quant combs through price ratios and mathematical relationships between companies or trading vehicles in order to divine profitable trading opportunities. During the 1980s, a group of quants working for Morgan Stanley struck gold with a strategy called the pairs trade. Institutional investors and proprietary trading desks at major investment banks have been using the technique ever since, and many have made a tidy profit with the strategy. Mean reversion is crucial because it’s the fundamental principle that makes pairs trading profitable.
Fundamental and technical analysis for pairs trading
Quantitative hedge funds do this and they might have thousands of stocks and make thousands of trades in their high-frequency strategy. To do stocks pairs trading well, we should have many pairs (maybe hundreds) running at appropriately low position sizes. One stock may significantly jump ahead or fall behind the other (i.e., fall out of correlation), but such anomalies have, historically, turned out to be short-term blips.
This will result in a loss since stock A is increasing at a rate lower than stock B and you are short on stock B. A perfect positive correlation is when one variable moves in either an upward or downward direction and the other variable also moves in the same direction with the same magnitude.

Well-executed pairs trading strategies typically achieve win rates between 55-65%. However, success rates can vary significantly based on market conditions, pair selection criteria, and risk management practices. A typical pairs trade usually lasts between 5 to 20 lessons in corporate finance days, depending on market conditions and the specific strategy used. Trades are typically closed when prices converge to their mean relationship or when stop-loss/time-based exits are triggered. Risk management forms the foundation of successful pairs trading by protecting capital and optimizing returns through systematic controls.
These highly correlated securities might start diverging in their respective price movements, and they can occur for a few minutes, weeks, or months in the long term. While this would seem to be the most straightforward step in the investment process, there are a few subtleties. Generally speaking, the short side of a trade should be executed and filled before the long order is placed.
Fortunately, using market-neutral strategies like the pairs trade, investors and traders can find profits in all market conditions. The long/short relationship of two correlated securities acts as a ballast for a portfolio caught in the choppy waters of the overall market. Good luck with your hunt for profit in pairs trading, and here’s to your success in the markets.
A pairs trading strategy is one of the most popular strategies when it comes to finding trading opportunities between the two stocks that are co-integrated. 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. It’s one with no directional bias—it doesn’t matter if the prices of both securities in a pair go up or down. In the case of pairs trading, all that matters is whether their relative prices converge back toward their historical spread levels. 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.
A trader is buying the underperformer and selling the outperformer, on the basis that this relationship will change course in due course. However, financial markets are constantly changing, and there are times when the relationship evolves, and the under/over-valuation does not mean revert. In addition, the strategy can be successful in up, down and sideways markets.
Pairs trading strategy
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. However, if you choose to trade 2 stocks, consider doing it over a limited time period (e.g. during the COVID-19 crisis, cruise stocks move together) or use another qualitative layer of analysis. Moreover, profits and losses from these idiosyncratic stock effects might cancel out because you have exposure to many stocks. After a few trades, you can have a feel for the average divergences and convergences, i.e. deviations.
The beauty of pairs trading is that it can be utilised by both fundamental investors and technical analysts. To illustrate the potential profit of the pairs trade strategy, let’s consider Stock A and Stock B, which have a high correlation of 0.95. These stocks temporarily deviate from their historical correlation, dropping to 0.50. A pairs trade strategy hinges on the historical correlation of two securities. For this strategy to be effective, the two securities must exhibit a high positive correlation. This correlation is the linchpin behind the strategy’s profitability.
The key driver of this strategy could be that the stocks participating in the same should necessarily have a higher rate of positive correlation. Pairs trading has the potential to achieve profits through simple and relatively low-risk positions. The pairs trade is market-neutral, meaning the direction of the overall market does not affect its win or loss.
