Because the long and short positions offset each other, pairs trading can be somewhat immune to movements of the overall market, thus eliminating or reducing market risk – theoretically at least. Sometimes we can get a loss on both trades or other times even see profits on both the long and the short trade. The risks of loss from investing in CFDs can be substantial and the value of your investments may fluctuate.

BTC is the most widely traded digital asset and the most integrated into the cryptocurrency market.

Generally, the service road follows the highway closely but terrain or development will sometimes cause the 2 to diverge. The area between the highway and the service road can be thought of as the spread—the measured distance between the 2 objects traveling together. The pairs trader attempts to measure the spread with statistics in an effort to find a tradable relationship of inequality opportunities.

In short, a quant combs through price ratios and mathematical relationships between companies or trading vehicles in order to divine profitable trading opportunities. During the 1980s, a group of quants working for Morgan Stanley struck gold with a strategy called the pairs trade. Institutional investors and proprietary trading desks at major investment banks have been using the technique ever since, and many have made a tidy profit with the strategy. The beauty of pairs trading is that it can be utilized by both fundamental investors and technical analysts.

Probably the best example of what not to do with a pairs trading strategy is the Long Term Capital Management meltdown. I won’t go into the details here, but there is plenty written about this incident and it makes a fascinating and informative case study.

Plan your trading

However, no matter where the general market goes, one of the positions will always show a profit while the other one will show you a loss. In very rare circumstances you can end up with two winning or losing positions. Trading pairs allow you to compare the performance between different cryptos on the market. For example, every crypto listed on Phemex has a pair to illustrate the current value of the coin. The USDT stablecoin is used to indicate the value of the crypto compared to USD.

You can also learn more about Mean Reversion Trading Strategies to use market data and statistical concepts, here is a brief video. It is defined as scenarios where you take profit before the prices move in the other direction. For instance, say you are LONG on the spread, that is, you have bought stock A and sold stock B as per the definition of spread in the article. This new distribution will have a mean of 0 and a standard deviation of 1.

  1. The trader will develop a feel for which of these options more suits their particular style, and may make different decisions for different pairs at different times.
  2. To understand how these potential pairs correlate, you can use tools such as the Coinmetrics correlation chart.
  3. A trade that sees profits of $1000 on one day, but then the second day sees that fall to $500 has a drawdown of $500.
  4. We can convert these raw scores of spread into z-scores as explained below.

Moreover, the average price movement of the different future contracts are different too. Thus, we need to account for these to make sure the size our bets right. You should add your own flavour to the strategy (see the rest of this section) to outsmart your competiton. The bottom-up method entails collecting all the data under the sun and checking which 2 (or more) assets behave similarly.

Model-based pairs trading

One estimate of this quantity is the half-life of mean reversion, which is defined for a continuous mean reverting process as the average time it takes the process to revert half-way to the mean. The Cointegrated Augmented Dickey Fuller (CADF) test finds a hedge ratio by running a linear regression between two series, forms a spread using that hedge ratio, then tests the stationarity of that spread. In the following examples, we use some R code that runs a linear regression between the price series of trade99 review Exxon Mobil and Chevron to find a hedge ratio and then tests the resulting spread for stationarity. We use the Bollinger Bands indicator to spot the times when the correlation between the two stocks has moved too far from the norm, which will result in a trading opportunity. Overall, the two trades matched should give us a neutral or risk-free position that allows traders to make a profit in the market. These risks can make it harder for you to profit from trades and minimize risks at the same time.

Notice however while that line is the global line of best fit, there are clusters where this line isn’t the locally best fit. We’ll likely find that points in those clusters occur close to each other in time, which implies that a dynamic hedge ratio may be useful. We’ll return to this idea later, but for now, we’ll use the slope of the global line of best fit. As a general rule when the stock ratio reaches the upper BB or 2 standard deviations, you can sell Tesla and Buy GM. However, when the stock ratio touches the lower BB or 2 standard deviations, you should buy Tesla and sell GM. In the chart below we can see that General Motors and Tesla often move in tandem.

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 the trader to pocket the proceeds from one or both of the positions. Today, pairs trading is often conducted using algorithmic trading strategies on an execution management system. These strategies are typically built around models that define the spread based on historical data mining and analysis.

It is easy to create threshold levels for this distribution such as 1.5 sigma, 2 sigma, 2.5 sigma, and so on. Based on this assumption a market neutral strategy is played where A is bought and B is sold; bought and sold decisions are made based on their individual patterns. Quantitative hedge funds do this and they might have thousands of stocks and make thousands of trades in their high-frequency strategy. You will know when to enter the trade and when not to, even as the 2 assets diverge and everyone else is entering the pairs trade.

For the pair of stocks to be traded in a pairs trading strategy, it is required that the time series is stationary. A stationary time series makes effective and precise predictions. For instance, if your pairs trading strategy is based on the spread between the prices of the two stocks, it is possible that the prices of the two stocks keep on increasing without ever mean-reverting. In the case of a pairs trading strategy, the two stocks or the financial instruments need to be trending at a similar mean price and remain close to each other. But, on certain occasions, one of the instruments may go through a short period of deviation from another in terms of price.

Is this case, you are betting that the 2 assets will become increasingly different from each other as time goes by. Maybe some of them don’t move as expected on Mondays, December or some other time-based conditions. Thousands of hedge funds are scouring the face of the earth to find pairs that work. I do believe that in general, it is easier to find non-stock assets that move similarly.
