Cointegration also does not necessarily imply that a profitable trading relationship exists. When we say buy, we have a long position in 3 lots of Nifty and have a short position in 1 lot of MSCI. Pairs traders seek instruments whose prices tend to move together; in other words, whose prices are correlated. You also obviously want to analyze multiple relationships at a time, because you spend very little time in the market by only trading when their is suitable divergence. Banking stocks are always highly co-related since there long term movement depends on the same economic or news based factors.

Pair trading is a trading strategy that matches a long position in one stock/asset with an offsetting position in another stock/asset that is statistically related. Pair trading is a mean reversion strategy where we bet that the prices will revert to their historical trends. As the trading logic is.

## The importance of correlation

I have been in the industry for over 30 years and have traded pairs in the past, but never heard that term. I'll watch out for you on Fridays Yes, cointegration addresses a lot of the issues with correlation based trading. The concept is super easy, you basically just regress one variable onto another and select a scalar beta value for the one you regressed such that their linear combination forms a stationary process.

Sounds good in theory, in practice it's rather tough because some limitations exist. I know this technique came into and left fashion in the prop trading and hedge fund industry some time ago, but I believe it can still be viable.

I'm sorry if my last post was insulting! It was not insulting. I am in the business, but I was interested in the post, not to sell my services. Thank you for the follow up. Thanks for the spiderfinancial link I will check it out.

Yeah jtrader33 , I've definitely seen that to be the case in some instances. I'm saying "more than excel can handle" just because dealing with tick or minute data in excel seems like a nightmare to me.

There are definitely pairs trading opportunities at higher timeframes, and there's probably some happy medium specific to each pairs trading opportunity where the marginal utility of trading lower timeframes is outweighed by costs of trading etc. If life were as pretty as textbooks this would be a classic convex optimization problem haha. Any help would be great.

Stupid question above, please do delete I see it is given for moderation. Maybe I am confused. Very nice excel sheet indeed. However, one query thou, is it possible to update the daily and historical data just the way you have done on your web excel sheet on our local machine excel sheet and if possible cud you share the info one liner formula for any one scrip. Even if you are unable to share, still many many kudos to you for sharing such a utility. There is no one liner formula that can be used for Microsoft excel.

But you can definitely use Macros. See below excel sheet, you would find some clue: Is the excel sheet working properly? Please see the updated link in the post: Few curious fellows play with the sheet often and make it unusable.

The first step in finding suitable pairs is to look for securities that have something in common, trade with good liquidity and can be shorted. Because of similar market risks, competing companies within the same sector make natural potential pairs and are a good place to start.

Examples of potentially correlated instruments might include pairs such as:. The next step is to determine how correlated they are. You can measure this using a correlation coefficient described above , which reflects how well the two securities are related to each other. The specific calculations behind the correlation coefficient are somewhat complicated and fall outside the scope of this tutorial; however, traders have several options for determining this value:.

After the correlation coefficients have been determined, the results can be used as a filter to find the pairs that show the most potential.

Once you find correlated pairs, you can determine if the relationship is mean reverting ; that is, when price does diverge, will it revert to its statistical norm?

Standard deviation calculated as the square root of variance is a statistical concept that illustrates how a specific set of prices is divided or spread around an average value.

A normal probability distribution can be used to compute the probability of occurrence of any particular outcome; in normal distribution:. If the pair reverts to its mean trend, the trade can be profitable. When two instruments are highly correlated, certain events can cause a temporary weakness in correlation. Because many factors that would cause price movements would affect correlated pairs equally such as Federal Reserve announcements or geopolitical turmoil , events that trigger weakness in correlation are generally limited to things that primarily impact only one of the instruments.

For example, divergence can be the result of temporary supply and demand changes within one stock, such as when a single large investor changes positions either through buying or selling in one of the securities represented in a pair.

Examples of developments include:. In general, the more likely the announcement is to influence price, the greater the likelihood the exchange will call for a trading halt until the news is disseminated to the public. Additionally, if a U. The price moves that trigger a pause are:.

Depending on the event, the price change can be very short-term or can result in a trend change. Correlation By Jean Folger Share.
