Answer (A):
Need more data to select the better adviser
Explanation:
Adviser A averaged 19% return on the investment which is more than that of Adviser B who averaged 16% return on investment. However, adviser A has a beta of 1.5 which is also greater than that of Adviser B who has a beta of 1. This means that adviser A made a more riskier investment and hence a higher average return on investment. We need more data to tell which adviser performed better in relation to each other.
Answer (B):
Investment Adviser B
Explanation:
[tex]R_{f}[/tex] = T-bill rate = 6%
[tex]R_{m}[/tex] = Market return = 14%
[tex]R_{m} - R_{f}[/tex] = Market risk premium = 14% - 6% = 8%
[tex]ER_{a}[/tex] = Average Return by Adviser A =19%
[tex]\beta _{a}[/tex] = Beta of Adviser A = 1.5
[tex]ER_{b}[/tex] = Average Return by Adviser B =16%
[tex]\beta _{b}[/tex] = Beta of Adviser B = 1
CAPM Equation is [tex]ER_{i} = R_{f} +\beta (R_{m} - R_{f} ) +\alpha[/tex]
For Adviser A
[tex]ER_{i}[/tex] = 6 + 1.5 (14 - 6) = 18%
The expected average return for the investment is 18% which means that Adviser A over performed the market by 1 %
For Adviser B
[tex]ER_{i}[/tex] = 6 + 1 (14 - 6) = 14%
The expected average return for the investment is 14% which means that the Adviser B over performed the market by 2 %
Clearly, Adviser B performed better than Adviser A.
Answer (C):
Adviser B
Explanation:
In this part, the [tex]R_{f} = 3 %[/tex] and [tex]R_{m} = 15%[/tex]
All else remains the same
We make similar calculation as in part B
