It is time for a practical example. We have a population of five observations – 1, 2, 3, 4 and 5. Let's find its variance. We start by calculating the mean 

This paper applies minimum variance portfolio optimization to the Baltic equity markets and Section 4 presents empirical findings that are later analyzed in. Variance of the portfolio: σp2 = wD 2σD2 + wE2 σE2 + 2 wD wE Cov(rD, rE) Using this definition, the expected return of A is 0.35 * 10% + 0.35*(-4%) +  The beta parameter for a portfolio of N risky assets is the sum of the 4. Stock A has greater total risk, as measured by the variance of returns.
