The document describes a Markowitz portfolio analysis with two risky assets using an efficient set. It provides the expected returns and standard deviations of the two assets, as well as their correlation. It then shows a dynamic chart of the efficient set with the two risky assets, depicting how the blue Markowitz efficient frontier changes as the correlation is adjusted. The computational numbers below the chart are not as instructive as the graphical representation of the efficient frontier.
