In today’s issue, I’m going to show you how to build a pairs trading strategy in Python. Pairs trading (sometimes called statistical arbitrage) is a way of trading an economic relationship between two stocks. For example, two companies that manufacture a similar product with the same supply chain will be impacted by the same economic forces. Pairs trading tries to model that relationship and make money when the relationship temporarily breaks down. Pairs trading relies on cointegration. Cointegration is a statistical method to test the stationarity between two-time series.

Stationarity describes a time series that has no trend, a constant variance through time, and no seasonality. The “pair” is a linear combination of both stocks: one you buy and one you sell. An ideal pairs trading scenario is when two stocks are cointegrated. In other words, there is a stable linear combination between them. The strategy will enter trades if that relationship breaks down. The secret to pairs trading is picking the right pairs to trade.

To do this, traders start with buckets of stocks that are related economically. Then they use big data sets to crunch through millions of pairs to find anomalies to exploit. The post “Build a Pairs Trading Strategy in Python: A Step-by-Step Guide” was originally published on Databento. This article presents a commonly used strategy and is intended solely for demonstration and educational purposes. It is often taught in classrooms as an example of developing a trading strategy. This information should not be viewed as a guaranteed method for achieving success.

Pairs trading is a form of statistical arbitrage that takes advantage of mean reversion or convergence in the prices of two instruments. The simplest variation of this strategy involves taking long and short positions simultaneously on a pair of cointegrated instruments.

But more generally, you can construct a spread from any linear combination of the two instruments with the approach in this tutorial — even going long simultaneously on two instruments. This project involves using a combination of statistics along with financial thoery to demonstrate a popular trading strategy used in equity markets: Pairs Trading. I used the data from Yahoo Finance, which provides historical financial data for free. This data was extracted via the yFinance Python module. The following are the modules we will use in this notebook. However, the program relies on many more dependencies than what is shown here.

Please be sure to set up a virtual enviroment and install the requirements.txt file before running this programming on your own. Pairs trading strategy is short-term and leverages the Law of One Price, an essential economic concept. This pairs trading strategy with Python involves simultaneously placing two positions in related securities to exploit short-term price divergences. To illustrate this strategy, consider two imaginary financial instruments, Company A and Company B, whose prices diverge over a specified period. By taking a long position in the underpriced security (Company B) and a short position in the overpriced security (Company A), you can capitalize on the price convergence. This article delves into the intricacies of pairs trading and explores the data visualization of JPMorgan Chase (JPM) and Bank of America (BAC) as a practical example.

Cointegration is a critical aspect of this pairs trading strategy, ensuring a long-term relationship between the two variables. We’ll take you through the steps of testing for cointegration and understanding the results. The z-score, a transformation of the spread, plays a pivotal role in identifying entry and exit points for pairs trading. The article details the calculation of the z-score and setting thresholds to determine when to initiate or close positions. Furthermore, we discuss the entry and exit rules (trading rules) for pairs trading, providing the necessary Python code for implementation. The article concludes by guiding you through the backtesting process, transforming the results into a data frame, calculating cumulative returns, and visualizing the equity curve.

Pairs trading with Python offers a comprehensive approach to profiting from short-term price divergences between related securities. Pairs Trading takes a good part of its theory in an essential economic concept, the Law of One Price. Build and backtest a pairs trading strategy with Python. Get the code: Pairs trading uses cointegration tests to assess a stable relationship between assets. If that relationship breaks, we can take advantage.

Pairs trading is a market-neutral strategy used to exploit the relative value discrepancies between two correlated stocks. We buy an “undervalued” stock and sell an “overvalued” one with the assumption the relationship will mean revert. Pairs trading involves some basic statistics which are easy to implement in Python. In today’s newsletter, we’ll build a basic pairs trading strategy and backtest it with VectorBT Pro.

In practice, pairs trading starts with identifying two stocks with a strong historical correlation. Traders monitor the price spread between these stocks and trade them when deviations occur.
