Sample standard deviation refers to the statistical metric that is used to measure the extent by which a random variable diverges from the mean of the sample. From there, the formula is: If you have covariances instead of correlations, the formula is: If you assume the correlations are all 0 (the assets are completely independent), then the last three terms go away. There are three main ways of computing VaR: the historical method, variance-covariance method, and Monte Carlo Simulation. Is this happening to you frequently? Any views or opinions expressed above may not reflect those of Seeking Alpha as a whole.
