This indicator is positive when both securities move in the same direction, either up or down and it’s negative when both securities move in an opposite direction. The correlation coefficient is a value that indicates the strength of the relationship. The coefficient can take any values from -1 to 1. The interpretations of the values are: -1: Perfect negative correlation. The variables tend to move in opposite directions (i.e., when one variable increases, The formula for correlation is equal to Covariance of return of asset 1 and Covariance of return of asset 2 / Standard. Deviation of asset 1 and a Standard Deviation of asset 2. ρ xy = Correlation between two variables. Cov(r x , r y ) = Covariance of return X and Covariance of return of Y. Once correlation coefficient is a number from -1 to 1, or any number in-between. If two data sets move in lock step in the same direction and by the same amount, they have a correlation coefficient of 1. If they move by the exact same amount but in the opposite direction, the number would be -1. Stock Correlation Calculator.
