Computing Portfolio Standard Deviation. The portfolio standard deviation or variance, which is simply the square of the standard deviation, comprises of two key parts: the variance of the underlying assets plus the covariance of each underlying asset pair. Viewing a portfolio with two underlying assets, X and Y, we can compute the portfolio Portfolio variance is a statistical value that assesses the degree of dispersion of the returns of a portfolio. It is an important concept in modern investment theory. Although the statistical measure by itself may not provide significant insights, we can calculate the standard deviation of the portfolio using portfolio variance.
