Advantages of Pairs Trading Strategy
If you are a $10 billion quant hedge fund, then yes, you have the resources to collect plenty of data. E.g. Futures and ETFs of the same products should behave similarly. The 10-year US bond might move similarly to the 10-year Canadian bond if both countries’ central banks are expected to behave similarly.
There are many reasons that pairs trading appeals to different types of traders.
This article explores the nuances of what is the pairs trading strategy, providing a robust foundation for both beginners and seasoned traders looking to refine their approach. The first and foremost step of creating a pairs trading strategy is the co-integration of the pair. Once the pair of stocks is co-integrated, they can be considered for the pairs trading strategy. For finding out the co-integration, Augmented-Dickey Fuller Test is used. 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.
If the market condition changed and the average deviation is 10%, then a deviation of say 15% is appropriate as your entry and exit points. This means that before you enter your hypothetical trade, don’t look at any potential exits. Usually, we check for data cleanliness at the backtesting with code stage. We look for potential errors and try to get data from multiple sources to compare.
A major assumption of the strategy is that the historical price relationship will continue to hold in the future. Hand in hand with this is an assumption that when the price ratio diverges away from the mean, it will revert with time. Historically, pairs trading has seen its fair share of both triumphs and setbacks. Successful cases often involve pairs within the same industry, for instance, technology stocks or automotive companies, where external factors impact them similarly. The non-directional nature of pairs trading means it’s less exposed to market trends. This implies that the spread between the prices of two correlated pairs will revert to its historical average.
Gold is higher after rebounding by Best time of day to trade forex 0.31% yesterday a day after plunging 3.35% on Monday (today it is up around 0.75% at the start of the day). Finally, Bitcoin is higher by $1100 or 1.22% at $93050 currently. The price fell 3 of the last 4 days after pushing Bitcoin 100K on Friday (peaked at $99800). All trades presented for customer compensation should be considered hypothetical and should not be expected to be replicated in a live trading account.
These products may not be suitable for everyone and you should ensure that you understand the risks involved. This occurs when one asset becomes overvalued relative to the other. In other words, the trader waits for a weakness in the correlation between the two assets before entering the trade. Consider that both metals fall and gold drops python math libraries by 8%, while silver falls by 10%. The gain on the short silver position would be partly offset by the loss on the long gold position, leaving you with a 2% net gain. Correlations can change over time, and strengthen and weaken, as well as changing their correlation from positive to negative.
Pairs trading cointegration is very similar but the price ratio will usually vary around a 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. Option traders use calls and puts to hedge risks and exploit volatility (or the lack thereof). A call is a commitment by the writer to sell shares of a stock at a given price sometime in the future. A put is a commitment by the writer to buy shares at a given price sometime in the future. As the two underlying positions revert to their mean again, the options become worthless allowing review manias, panics, and crashes the trader to pocket the proceeds from one or both of the positions.
Market neutrality
Among these could include blue-chip stocks such as Apple and Samsung vs Motorola and Nokia. Google and Microsoft could be included in this stock pair trading strategy as well, but they tend to have higher exposure to other markets. In summary, pairs trading is a strategy that relies on statistical correlations between two stocks to create market-neutral opportunities. While it offers potential profits and risk mitigation, it also comes with its challenges, notably the requirement of high correlations. The example provided demonstrates how a pairs trade can lead to profits when securities return to their historical correlation. This strategy showcases the importance of thorough research and analysis in the world of financial trading.
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. Sometimes we can get a loss on both trades or other times even see profits on both the long and the short trade.

In the chart below, the potential for profit can be identified when the price ratio hits its first or second deviation. When these profitable divergences occur it is time to take a long position in the underperformer and a short position in the overachiever. The revenue from the short sale can help cover the cost of the long position, making the pairs trade inexpensive to put on. Position size of the pair should be matched by dollar value rather than by the number of shares; this way a 5% move in one equals a 5% move in the other. As with all investments, there is a risk that the trades could move into the red, so it is important to determine optimized stop-loss points before implementing the pairs trade.
This article looks at what pairs trading is, how it works, and its advantages and disadvantages (pros and cons). 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. But sometimes, two historically correlated stocks diverge and stay that way, due, perhaps, to a permanent fundamental change in one of the two companies. Technical analysis focuses on market action — specifically, volume and price. When considering which stocks to buy or sell, you should use the approach that you’re most comfortable with.
