Portfolios that represent combinations of the risk-free asset and the market portfolio are plotted on the: A. capital asset pricing line. B. capital market line. C. utility curve.
The introduction of a risk-free asset changes the Markowitz efficient frontier into a straight line. This straight efficient frontier line is called the capital market line (CML). Investors at point Rf have 100% of their funds invested in the risk-free asset. Investors at point M have 100% of their funds invested in market portfolio M. Between Rf and M, investors hold both the risk-free asset and portfolio M. To the right of M, investors hold more than 100% of portfolio M. All investors have to do to get the risk and return combination that suits them is to simply vary the proportion of their investment in the risky portfolio M and the risk-free asset.
