What often works is your experience and a broad range of potent skill sets that allow you to grasp a hold of the complete scenario before jumping to conclusions.
- It is defined as scenarios where you take profit before the prices move in the other direction.
- Experienced traders know that currency pairs have a close relationship with each other.
- Whereas a perfect negative correlation is when one variable moves in the upward direction and the other variable moves in the downward (i.e. opposite) direction with the same magnitude.
- During the 1980s, a group of quants working for Morgan Stanley struck gold with a strategy called the pairs trade.
- Now, both ‘a’ and ‘b’ increase in such a way that the value of the spread decreases.
For example, in most cases, when the EUR/USD falls, the GBP/USD or AUD/USD will also fall as well. The expectation is that spread will revert back to the mean or 0. In a profitable situation, the mean would be approaching zero or very close to it. You can keep the take profit scenario as when the mean crosses zero for the first time after reverting from the threshold levels. To be able to identify these threshold levels, a statistical construct called z-score is widely used in pairs trading. A stationary process has very valuable features which are required to model pairs trading strategies.
Stop loss is defined for scenarios when the expected outcome does not occur. For instance, if we chose entry signals at 2-sigma, we are expecting that the spread will revert back to the mean from this threshold. Calculate z-score of ‘s’, using rolling mean and standard deviation for a time period of ‘t’ intervals. The main difference from the Dickey Fuller Test is that the Augmented Dickey Fuller test can also be applied to a large sized set of time series models. The large sized what is the yield of a bond time series models can be more complicated and hence, the DF test was modified into the ADF Test. The augmented Dickey-Fuller test is an extension of the standard Dickey-Fuller test, which also checks for both stationarity and non-stationarity in the time series.
When it is rising, you simply buy the pair and hope that its price will continue moving in that trend. On the other hand, when it is declining, you sell it and benefit when the price is falling. This is the most difficult and time-consuming step in the process. It includes selecting a trading universe, constructing and testing a model, if one is to be used, and creating general buy and sell guidelines.
Geert Rouwenhorst, the authors attempted to prove that pairs trading is profitable. Using a large set of data from 1967 to 1997, the trio found that over any six-month trading period, the pairs trade averaged a +12% return. To distinguish profitable results from plain luck, their test included conservative estimates of a training describing how to setup and run tensorflow on codenvy transaction costs and randomly selected pairs. Thus, one should be careful of using only correlation for determining the pairs of the stocks while performing the pairs trading strategy. A pairs trading strategy is one of the most popular strategies when it comes to finding trading opportunities between the two stocks that are co-integrated. The outcome of any of these situations will be dynamic and unknown, but the correlations are almost certain to change.
The Secret to Finding Profit in Pairs Trading
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.
We can convert these raw scores of spread into z-scores as explained below. The assumption is that highly correlated stock pairs will continue to move in a comparable, measurable, and hence predictable manner. And if their prices diverge, it can present a profit as prices converge back toward their correlated state.

Maybe some of them don’t move as expected on Mondays, December or some other time-based conditions. Certain assets diverge how to sell nfts the motley fool during certain hours and converge during other hours. However, if you understand the assets well, you can choose and time your trades better than others.
Relying on the historical notion that the two securities will maintain a specified correlation, the pairs trade can be deployed when this correlation falters. 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. In this regard, to help minimize the risk of an unexpected event, professional traders can use the pair trading strategy to protect a particular trading idea. Pairs trading can be a valuable addition to any diversified portfolio. It offers a non-correlated source of returns, reducing overall portfolio volatility and potentially increasing risk-adjusted returns.

On the other hand, when the result is close to -1, it means that the two currency pairs are inversely correlated. In other words, the two pairs tend to move inversely to each other. At the same time, some financial assets are known for their inverse correlation. This happens when two financial assets moves in different directions.

Maybe you can use the US 2-10 bond spread to lead the US stock ETF and a German 2-10 bond spread to lead the European stock ETF. Instead of just looking at 2 assets, look at what leads those assets. This is because it is hard to find 2 stocks that are very similar. If you are a $10 billion quant hedge fund, then yes, you have the resources to collect plenty of data.
Statistical arbitrage involves using statistical models to identify mispriced assets and take advantage of price discrepancies. Traders can use either fundamental or technical data to construct a pairs-trading style. Our example here is technical in nature, but some traders use a P/E ratio or other fundamental factors to measure correlation and divergence. In order to do the pairs trading, you must devise a trading strategy .
It not only provides a unique opportunity to profit in both bullish and bearish markets but also contributes to portfolio diversification and risk management. Incorporating pairs trading into your trading arsenal can be a wise decision for seasoned traders looking to enhance their returns and minimize risk. Below is a weekly chart of the price ratio between Ford and GM (calculated by dividing Ford’s stock price by GM’s stock price). This price ratio is sometimes called “relative performance” (not to be confused with the relative strength index, something completely different). The center white line represents the mean price ratio over the past two years.
The value of +1 means there exists a perfect positive correlation between the two variables, -1 means there is a perfect negative correlation and 0 means there is no correlation. If you make 0.5% per trade (net of fees) and manage to fire 5 trades a month, you will make 2.5% a month. For futures, the dollar value per unit of movement is usually different for different future contracts. Entering an equal dollar amount for both assets usually doesn’t work, especially if the 2 assets are very different.
