"Markowitz showed that the variance of the rate of return was a meaningful measure of portfolio risk under a reasonable set of assumptions. He also derived a formula for computing the variance of a portfolio. These formulas for the variance of a portfolio not only indicate the importance of diversifying your investments to reduce the total risk of a portfolio, but also showed how to effectively diversify. Markowitz theory achieved the following: - Markowitz demonstrated that the variance of the rate of return is a meaningful measure of portfolio risk under reasonable assumptions. - Derives the expected rate of return for a portfolio of assets and an expected risk - measure Shows that the variance of the rate of return is a meaningful measure of portfolio risk - Derives the formula for computing the variance of a portfolio, showing how to effectively diversify a portfolio.
