First, we removed stocks that were delisted, exchanged, or merged during our sample period since those stocks are no longer tradable. Next, we removed stocks that have negative prices which will be problematic for further analysis. Stocks that are constantly trading at-low-volume also have to be removed since improper trading executions can largely change their stock prices and altered history.

Martin shorted Netscape and went long Microsoft, and he said that it was one of the few pairs trades where he made significant money on both legs of the trade. This table is the result of running cointegration tests between every possible pair in this list of stocks, and displays the cointegration value as a color. Generally, in the pairs trading world, a cointegration of 95% or higher is considered significant, and could be indicative of a mean-reverting pair. In other words, when two correlated stocks diverge, cointegration measures how likely two correlated assets return to their correlated state. I’m not a statistician so do your own research to truly understand how the math works.

That’s why pair trades are important to those who favor momentum type stocks. While momentum investing does not advocate buying low and selling high, momentum investors normally do not wish to place their money into cheap stocks while waiting for them to recover over the long haul.

The pairs trading strategy works not only with stocks but also with currencies, commodities, and options. 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. This strategy allows you to potentially profit, regardless of market conditions. While pairs trading was traditionally set up for long-term stock investments, investors with shorter timescales can also take advantage of this trading strategy. Pairs trading strategies are usually meant to be short to medium term at the longest. Even the most highly correlated names tend to lose correlation over time.
Very Important: Keep Pairs Trade Durations Short
For the training data, we used the previous 700 days stock prices. After we train the model with our machine learning algorithm, we calculate the z-score with the generated model and decide whether we will long or short the stocks. The input of backtesting is the z-score history generated in the ‘trading strategy’ part and the price history. Based on the input, we keep calculating the earning and loss of our stock and inverse. We also track the total asset history and return it as an output of backtesting.
You’re looking for the correlation to come back in line, resulting in a potential profitable 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.
Once, the relevant pairs have been identified, their price relations are extrapolated using supervised learning techniques such as Linear Regression. This overall methodology will help provide insight into the relations between various stocks and facilitate the generation of appropriate trading strategies for them. The idea behind a pairs trade is to take advantage of divergences in highly correlated securities. To increase the odds of success, track relationships over time, identify price divergences, and hypothesize when they may come back in line.

This chart kind of helps pin point pairs where existing cointegration relationship is about to break or new cointegration relationship is about to form. Chart 4 plots the trend of Adf Test Stats along with the critical value of the pair of interest. It gives you a sense of how tightly cointegrated the pair has been historically. In an ideal scenario, for a perfectly cointegrated pair, Adf Test Stats should always be less than the Critical Value at 95% confidence interval . An up trending ADF Test Stats line crossing over the Critical Value line from below clearly indicates that the cointegration is in danger and such pairs should be dropped from watchlist.
One of the more obvious relationships is between the S&P 500 Index and the Dow Jones Industrial Average($DJI)—they generally move in the same direction. Because more than 40% of harvested corn is pegged for ethanol production. Meanwhile, corn futures and soybean meal futures compete as substitutes to nourish cattle.

So for all practical purposes, the two roads ‘behave’ somewhat identically, except at that point where the tree briefly obstructed the path on the service road. If you have ever been on an interstate highway, then you would have noticed that the highway usually includes the main highway, on which the vehicles zoom by at full speed. On either side of the highway, it is common to find a single road, which is often called the service road. The service road is used to give access to private driveways, shops, houses, industries or farms.
