Let’s take a deeper look into the taxonomy of pairs trading strategies. It is hard to overestimate the influence that pairs trading has had on the industry. The initial members of the team consisted of mathematicians and physicists under Nunzio Tartaglia, who later branched off to establish such renowned independent practitioners as D.E. Many stories from the golden era of statistical arbitrage, about the business and its practitioners, have been mythologized by the industry. Statistical arbitrage is typically broken down into factor investing and the mean-reverting portfolios of pairs trading. We should add that in its simplest form pairs trading refers to trading only 2 assets but it can be extended to an n-dimensional mean reverting portfolio.
The advantage in terms of reaction time allows traders to take advantage of tighter spreads. In practice, I use statistical tests such as CADF and Johansen to help find potential hedge ratios for price series that I think have a good chance of generating a profit in a pairs trading strategy. Specifically, I don’t pay a great deal of attention to the statistical significance of the results. The markets are noisy, chaotic and dynamic, and something as precise as a test for statistical signficance proves to be a subotpimal basis for making trading decisions. Essentially, this assumes that two stocks that historically have moved in the same direction will continue to do so. So, pair traders look for highly related stocks – such as stocks in the same industry, and often direct competitors – that begin to diverge in their price movements.
- If executed properly, the market-neutral pairs trading strategy can take away a lot of the irritation out of trading.
- The pair’s price ratio – the price of one share divided by the other – must be determined, giving the trader a midpoint that he can chart.

- Pairs trading strategy demands good position sizing, market timing, and decision making skill.
- Notice however while that line is the global line of best fit, there are clusters where this line isn’t the locally best fit.
Another example is that certain assets diverge or converge during crisis times. You might be able to find opportunities that only exist during this period. However, if you understand the assets well, you can choose and time your trades better than others. https://g-markets.net/ If you see that divergences and convergences keep occurring, your strategy might have potential. If so, you can then consider moving on to actual backtesting with code. Futures are different from stocks in a way that they expire, usually every quarter.
The trader must be cognizant of the unexpected news releases affecting either of the instruments in a trade and be prepared to adjust their thinking accordingly. Likewise, they must be mindful of the pair’s price action and constantly adjust the risk/return profile of the trade. In such a situation, the trader could choose 1 of 2 options to prudently manage the trade moving forward. The trade could be immediately closed with a view that the additional return does not warrant the risk or the opportunity cost.

These divergences can take place over a period of a few minutes intra-day, or over a period of weeks or months in the longer term. Pair trading is a strategy for hedging risk by opening opposing positions in two related stocks, commodities, or other derivatives. This can be a way to profit no matter what conditions the market is in since profit is determined not by the overall market, but by the relationship between the two positions. While pair trading was originally developed and used by long-term investors, it can also be applied by day traders on shorter timescales. It’s also important to be aware of the notional value when putting on a pairs trade.
It didn’t take long for the pairs trade to attract individual investors and small-time traders looking to hedge their risk exposure to the movements of the broader market. “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.
Futures accounts are not protected by the Securities Investor Protection Corporation (SIPC). Pairs trading requires active monitoring and management continuation patterns and is not suitable for all investors. Discover the range of markets and learn how they work – with IG Academy’s online course.
Drift and risk management
The broad market is full of ups and downs that force out weak players and confound even the smartest prognosticators. 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. It is the responsibility of the trader to manage the position according not only to the predetermined buy and sell rules, but also to the changing market environment.
Disadvantages of pairs trading
With the rapid evolution of markets and advancement in technology, arbitrage opportunities have become scarcer and the margins – slimmer. The most critical part of any pair trade is how to identify the best trading currency pairs. If executed properly, the market-neutral pairs trading strategy can take away a lot of the irritation out of trading. Before utilizing the pair trading strategy we first need to make sure that the instruments we’re going to trade are correlated. What we want to see is a positive correlation where both instruments move in tandem.
Remember that each trade is its own risk event and should be treated as such. You manage the risk of a pairs trade by managing the risk on each individual trade as a stand-alone trade. If using options, you’ll need to know the assignment risk and what occurs near expiration.
In the chart below we can see that General Motors and Tesla often move in tandem. When the correlation stops, then we’re presented with a trading opportunity to short-sell General Motors when it’s outperforming and go long Tesla when it’s underperforming. Among the best pair trading stocks, Joe chooses to match his long Twitter position with an equal-size short Facebook position. We look at pairs trading – what it is, how investors can implement it as a strategy, and both the positives and negatives of using it. Pairs trading relies on the securities having a high statistical correlation. Most of the traders require a correlation of at least 0.80 which is very challenging to recognize.
Another approach: total least squares
If you believe the pair price will continue to go higher, and MNKY will continue to outperform XYZ, you could buy shares of MNKY and sell shares of XYZ. But if you believe the pair price will go lower, you could sell MNKY and buy XYZ. Pairs trading can be risky without a proper understanding of the financial markets. Learn how to apply a pairs trading strategy effectively in this guide. This is an advanced pairs trading strategy that relies on using stochastic processes to generate the optimal trading rules and policies for mean reverting portfolios.
Hence, it comes without saying that you have to be attentive to the nuances that come with the type of strategy you are using. Overlooking such details can render the whole procedure useless, even if all our assumptions are flawless and we account for every possible bias. In the chart below, we have identified an instance where Tesla’s stock price rallied sharply in value relative to GM stock price. However, no matter where the general market goes, one of the positions will always show a profit while the other one will show you a loss. In very rare circumstances you can end up with two winning or losing positions.
We’ll return to this idea later, but for now, we’ll use the slope of the global line of best fit. Customers who want to use their accounts for day trading must obtain the broker-dealer’s prior approval. Customers
must also be aware of, and prepared to comply with, the margin rules applicable to day trading. Spreads, straddles, and other multiple-leg options strategies can entail additional transaction costs, including multiple contract fees, which may impact any potential return. These are advanced options strategies and often involve greater risk, and more complex risk, than basic options trades.
