21 sie 2024 · The covariance calculation between stock A and stock B can also be obtained by multiplying the standard deviation of returns of stock A, the standard deviation of returns of stock B, and the correlation between stock A's and stock B's returns. Mathematically, it represents as, Cov (RA, RB) = ρ(A, B) * ơA * ơB.
9 lis 2022 · Covariance. Covariance is a measure of the degree of co-movement between two random variables. For instance, we could be interested in the degree of co-movement between the interest rate and the inflation rate. The general formula used to calculate the covariance between two random variables, \(X\) and \(Y\), is:
