Given the following information about the market r_m = 18 per cent, r_f = 6per cent, \sigma_m = 30 per cent.
(a) Calculate the slope of the capital market line (CML).
(b) Calculate the expected return for three mutual funds, namely, Aries (σ = 15 per cent), Taurus (β = 18
\, per cent), Gemini (σ = 24 per cent).
\, State the assumptions necessary for the application of the model.
(a) Slope of CML = r_m – r_f /\sigma_m = 18% – 6%/30% = 0.4
(b) Assumption: All mutual funds are efficient portfolios, otherwise
\, security marked line rather than capital market line should be used.
\, Expected rate = Intercept + Slope × Standard deviation
\qquad \qquad \qquad= r_f + [(r_m – r_f)/\sigma_m] \sigma_{\rho}
Expected\>return | Mutual\>fund |
6% + 0.4 × 15% = 6% + 6% = 12% | Aries |
6% + 0.4 × 18% = 6% + 7.2% = 13.2% | Taurus |
6% + 0.4 × 24% = 6% + 9.6% = 15.6 % | Gemini |
