How can I calculate the portfolio standard deviation in Excel?
To calculate the portfolio standard deviation in Excel, you can use the formula SQRT(SUMPRODUCT(COVARIANCE MATRIX, WEIGHTS MATRIX, TRANSPOSE(WEIGHTS MATRIX))). This formula multiplies the covariance matrix of the assets, the weights of each asset in the portfolio, and the transpose of the weights matrix, then takes the square root of the sum of these products.
