The portfolio risk is not simply a measure of its weighted average risk. risk, given a level of desired return, or maximizes the returns given a level of risk tolerance. The above can be checked with the capital weightage formulas for the minimum variance (risk).Substituting The equations to compute the covariance and correlation are given below. There is also a risk free return, which is secured by any investor by keeping his funds in say bank deposits or post office deposits or certificates. Let’s start with a two asset portfolio. b. The sum of the remaining elements can be written as: Hence, the variance of such a portfolio will be: For a fully diversified portfolio, we can assume that we have added every possible stock in our portfolio.

Portfolio risks can be calculated, like calculating the risk of single investments, by taking the standard deviation of the variance of actual returns of the portfolio over time.
