Explanation / Answer

Question - A

Alpha of 1.5% means, excess of expected return over the CAPM model prediction. Thus, 12% is the expected return but alpha is 1.5% it implies that CAPM model value = 12 - 1.5 = 10.5%

CAPM model = Rf + Beta ( Rm - Rf) = 10.5

Here Rf = Risk free rate ....... which had to be derived from equation

Rm = Market rate of return ......... Given = 13

Beta = 0.77

Rf + 0.77 ( 13 - Rf) = 10.5

Rf + 10.01 - 0.77 Rf = 10.5

0.23 Rf = 0.49

Rf = 0.49 / 0.23 = 2.13 .............. Select Option - B

Question - B

In the above table, weights are obtained by dividing individual amount with total of amounts. i.e 6000/23000, 5000/23000 and 12000/23000. In the last column we multiply beta values with respective weights and finally total up the last column to get portfolio beta = 1.28 ............ Select Option - B

Question - C

Select - Option - B .......... I, III

The term same risky portfolio implies a portfolio that matches the risk aversion of the client.
