Calculating portfolio returns using the formula A portfolio return is the weighted average of individual assets in the portfolio. The minimum variance portfolio rests where the line starts to curve and risk is at its lowest level as it relates to return. It is calculated by dividing the difference between portfolio return and risk-free rate by the standard deviation of negative returns.
