Most pairs trades will require a correlation of 0.80, which can be challenging to identify. Second, while historical trends can be accurate, past prices are not always indicative of future trends. Requiring only a correlation of 0.80 can also decrease the likelihood of the expected outcome. When a pairs trade performs as expected, the investor profits; the investor is also able to mitigate potential losses that would have occurred in the process. Profits are generated when the underperforming security regains value, and the outperforming security’s price deflates. Pairs trading was first introduced in the mid-1980s by a group of technical analyst researchers that were employed by Morgan Stanley, the multinational investment bank and financial services company.

Reliance of the High Statistical Correlation

The most important thing to beware of when pair trading is the assumption that a correlation is real, and that two stocks will return to that correlated relationship after any divergence. Just because two stocks have been correlated historically does not mean that they will continue to be correlated into the future. Identifying weak points in a correlation model can be extremely difficult, and the potential failure of the market neutral assumption in a pair trade is an inherent risk of this style of trading. To devise a pairs trading strategy, a trader will need the price data for the two markets, and then create a ratio (one market’s price divided by the other). When the ratio between the two moves outside its normal range then a trading opportunity is created. Online trading opened the lid on real-time financial information and gave the novice access to all types of investment strategies.

The strategy is not dependent on market direction, but rather on the correlation between the two markets. The relative performance of the two markets is the key element, and not just whether the market goes up or down, as is the case for those traders that only go long or short. It is extremely important that the evaluation of the correlation must be made carefully as any wrong assumption or prediction may result in the failure of the pairs trading strategy. As mentioned, if you are running a pair trading strategy on stocks, you probably need to run the strategy on more than a single pair of stocks. If you are running a pair trading strategy on stocks, you probably need to run the strategy on more than a single pair of stocks. In a nutshell, pairs trading works by betting that 2 or more securities will diverge or converge in price.

Example of a Pairs Trade with Stocks

For each stock of A bought, you have sold n number of stocks of B. Correlation is quantified by the correlation coefficient ρ, which ranges from -1 to +1. The correlation coefficient indicates the degree of correlation between the two variables.

For example, if you own BTC, then you can trade with any pairing listed on an exchange that includes BTC. Understanding trading pairs is necessary primarily for buying certain cryptocurrencies and for engaging in advanced arbitrage trading strategies. Once the trader finds two securities to trade, it is often then wise to test the pair with a short-term trade before committing to something longer.

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. For instance, a stock might move 1% a day on average, while a cryptocurrency coin moves 5% a day on average. Buying and shorting $1,000 on each will bias the impact of your pairs trade towards the cryptocurrency.

With an appropriately approved account, certain options spreads like verticals can offer lower capital requirements and defined risk. For example, you can allocate a relatively small amount of capital to a bullish vertical in one symbol and a bearish vertical in another. Because the risk is how to day trade forex defined, even if the pair’s correlation collapses (your bullish stock crashes and/or your bearish stock rallies), the verticals won’t exceed a specific max potential loss. Keep in mind, options still have greater and more complex risk than stocks, and options trading is not for everyone.

The pairs trade strategy uses statistical and technical analysis to seek out potential market-neutral profits. Pair trading depends only on the relationship between the two stocks being traded, rather than on the overall rise of decline of a sector or the markets broadly. That means that pair traders can find and profit on opportunities regardless of whether the market is gaining, losing, or moving sideways, or whether conditions are very stable or highly volatile.

Another way to do this is to run a “pairs” trading strategy that consists of more than 2 assets per strategy. To do stocks pairs trading well, we should have many pairs (maybe hundreds) running at appropriately low position sizes. 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.

The line of best fit over the whole data set has a slope of 1.68, which we’ll use as our hedge ratio. 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.

Suppose you buy 100 shares of stock A for $100 and short 100 shares of stock B for $50 as a pairs trading strategy. The two stocks are highly correlated, and you think stock A will outperform stock B by rising more (or dropping less). For example, you can use stocks as long as the two listings are correlated and have some type of relationship. But a long stock/short stock pairs trade can use up a lot of trading capital and comes with significant risk if the pair should move against you.

Pairs trading is a strategy that tends to use statistics to identify relationships, assist in determining the direction of the relationship, and then ascertain how to execute a trade based on the data. The pairs trader attempts to capitalize on market imbalances between 2 or more financial instruments, such as stocks or funds, in anticipation of making money when the inequality is corrected. Therefore, pairs trading involves choosing two securities that belong to the company having the same industry or are direct competitors. The assumption that the market is neutral expects that the stock that is outperforming will return to the neutral price, i.e., the price will decrease, whereas the underperforming stock will return to the neutral price. Choosing cryptocurrency pairs to implement an arbitrage trading strategy can be complicated.
