Answer:
50.0%
Explanation:
The computation of the information ratio is as follows
Information ratio = Alpha ÷ residual standard deviation
where,
Alpha is
= Average rate of return - required rate of return
The average rate of return is 18%
And the required rate of return is
= Risk-free rate + Beta × (Market rate of return - Risk-free rate)
= 7% + 1.25 × (15% - 7%)
= 17%
So, the alpha is
= 18% - 17%
= 1%
Therefore the information ratio is
= 1% ÷ 2%
= 50.0%
