Pair Trading is a direct way to profit from relative performance of two stocks by simply predicting which of the two will perform better in short term. It is based on the principal of Statistical Arbitrage The best part of Pair Trading is – “you do not need to worry about the stock price direction which may go either up or down”. If you choose the pairs smartly, you can benefit in both up trending and down trending market as what matters is the relative performance of the stock pair and not the direction of movement.
Pair Trading is basically a 3 step process:
Our pair trading tool enables you to identify, monitor and spot profitable pair trading opportunities with great ease. Let’s see how:
The first step in designing your pair trade is identifying stock pairs that are highly co-integrated i.e. move together. The thumb rule is – Look for stocks from the same sector, having similar business model and comparable market cap as they have the highest chance to be co-integrated over a longer time horizon. We will take TATAMOTORS and TATAMTRDVR as an example to understand the selection process better. Based on common sense, we can be fairly accurate in assuming that they can be an ideal example of co-integrated pair. Why? Because they have the same company as underlying i.e. Tata Motors. However, we will establish this fact using our tool. Till we validate this, forget that they are co-integrated pair. So choose these companies from the drop down as shown in picture below.
Click on Pair Trade Analysis button and you will get the following charts. Let’s call them Chart 1 and Chart 2 for simplicity.
Chart 1 – TATAMOTORS and TATAMTRDVR price comparison chart
Chart 2 - TATAMOTORS and TATAMTRDVR stock price difference and stock price difference mean chart
Let’s focus on Chart 1 first which is a visual representation of TATAMOTORS and TATAMTRDVR price comparison over last one year. By looking at the chart, we can very well establish the fact that there is a relationship between the two stock prices. Whenever price of first goes up, price of second follows and vice versa. However, the key point to note here is – The gap between the two stocks prices (Stock Price 1 – Stock Price 2) keeps on fluctuating in short term. Sometimes it increases and sometimes it decreases (seems like the stock price difference is mean reverting). Now to establish the fact that stock price difference is mean reverting (i.e. stock pair price is co-integrated), we need to focus on Chart 2 – which is a plot of Percentage Stock Price Difference (blue line) calculated as ((Price A - Price B)*100/Price B) and Mean of Percentage Stock Price Difference (the red line – value 42.97 ). As we can see in chart that the blue line (the price difference line) has a tendency to kiss the red line (mean line) and has crossed it multiple number of times in last one year. This proves that stock price difference is mean reverting and hence they are co-integrated.
Note* - While establishing mean reversion, it's mandatory that two line cross each other multiple times in a given timeframe. Be careful about the word “multiple”.
So post this analysis, we can now be fairly sure that we have chosen the right pair which is co-integrated and its price difference is mean reverting.
As we have now identified our target pair, it’s time to focus on spotting the real pair trade opportunity. In order to establish whether a pair trade opportunity exists or not, it is necessary to analyse the mean and standard deviation data that appears at the bottom of Chart 2, which for our case is:
Let’s find out the meaning of individual values one by one.
The Secret Sauce – The best profitable pair trade opportunity arises where the Current Deviation From Mean is either near Maximum Deviation From Mean or Minimum Deviation From Mean. In other words, Current Deviation From Mean should be significantly larger or smaller than Standard Deviation. How large or small depends on your risk appetite.
In our case, the current deviation is 13.28, while the standard deviation is 8.73. If we talk about our risk appetite, we are not too comfortable with the trade at this point of time. We would rather wait for current deviation to drift more towards max deviation i.e. 24.94. May be a value in the range of 18 to 20 will make us more confident. Having said that, you are free to choose your own deviation level, which will primarily depend on how much risk you can bear.
In general, the stock having larger relative price gain will shed the gain and stock with lower relative price gain with absorb more gain in coming trading sessions. To identify the relative gains or losses, zoom in on Chart 1 (The Price Comparison Chart). To zoom in you need to press and hold left click + drag on Chart 1. Zoom in results in following view for our case:
To gauge the relative outperformance or underperformance, focus on what has happened in last few trading session. In this case, TATAMOTORS is the relative outperformer since the price rise in last few days for TATAMOTORS has been quite steep as compared to TATAMTRDVR. Why? The slope of TATAMOTORS price chart is steeper as compared to TATAMTRDVR.
The Secret Sauce – Sell the relative outperformer and Buy the relative underperformer.
So for this case, short TATAMOTORS and buy TATAMTRDVR.
