Correlation Coefficient indicator
The correlation coefficient indicator is a statistical measure used to evaluate the strength and direction of the linear relationship between two financial instruments, such as stocks, indices, or any other time series data. The Pearson correlation coefficient is commonly used in finance to assess how closely two assets move in relation to each other. Calculation of the Pearson Correlation Coefficient: The Pearson correlation coefficient ( r r r ) is calculated using the following formula: where: n n n is the number of data points. x x x and y y y are the individual data points of the two financial instruments being compared. ∑ x y \sum xy ∑ x y is the sum of the product of the paired data points. ∑ x \sum x ∑ x and ∑ y \sum y ∑ y are the sums of the individual data points. Interpretation and Usage: Correlation Coefficient Values: r = 1 r = 1 r = 1 : Perfect positive correlation. The two assets move in the same direction. r = − 1 r = -1 r = − 1 : Perfect negative corre...
