What Is Correlation?


In the financial and investing sectors, correlation is a statistic that indicates the degree to which two securities move in relation to one another. It is a statistical concept that describes how two variables move in tandem with one another. When two variables move in the same direction, they have a positive correlation. They have a negative correlation if they travel in opposite directions.

A foreign exchange correlation is the relationship that exists between two currency pairings. When two pairs travel in the same direction, there is a positive ; when they move in opposing directions, there is a negative ; and there is no correlation if the pairs move arbitrarily with no discernible link. A negative correlation often referred to as an inverse correlation.

Assume a trader purchases two distinct currency pairings that adversely connected. Gains in one can be offset by losses in the other, which is a common hedging technique. Buying two correlated pairings, on the other hand, may quadruple the risk and reward potential, because both transactions will result in a loss or profit. Because the pairings travel in the same direction, they are not completely independent.

What is the Coefficient of Correlation?

It indicates the strength or weakness of a link between two Forex pairs. Correlation coefficients given in decimal numbers ranging from -100 to 100 or -1 to 1, with the decimal denoting the coefficient.

Anything below -100 indicates that the pairs travel nearly identically but in opposing directions, whereas anything above 100 indicates that the pairings move nearly identically in the same direction. The phrase “almost similarly” is significant since correlation only considers direction but not magnitude. For example, one pair may rise 100 pips (percentages in point), while another falls 70 pips.

Even if the magnitude of the movement differs, both pairings may have a very strong inverse correlation. If a reading is between -70 and 70, deemed to have a significant connection. Since the movements of one are substantially mirror in the movements of the other. Readings ranging from -70 to 70, on the other hand, indicate that the pairings are less associated. With Forex correlation coefficients close to zero, both pairings have little or no discernible link with one another.

Formula:

While this formula appears difficult, the main idea is that it compares data points from two pairs, x and y, to average readings within these pairings. The covariance is at the top of the equation, while the standard deviation is at the bottom.

Consider the data points to be the closing prices for each day or hour. The closing price of x (and y) compared to the average closing price of x (and y), allowing a trader to insert the closing and averaged values into the calculation to determine how the pairs move together. To obtain the average, numerous closing prices tracked in a program such as Microsoft’s Excel spreadsheet. Once numerous closing prices recorded, an average calculated, which constantly updated as fresh prices received. This entered into the formula, along with fresh x values.
