Explanation:

a. Since all the information is not given in the question so we are not able to give advise. As abnormal return is calculated from subtracting the expected return from the return. But no such information is provided in the question.

b. We know that

Abnormal return = Return - expected return

Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)

In case of First Investment Advisor:

The return is 19%

And, the expected return equal to

= 6% + 1.5 × (14% - 6%)

= 6% + 1.5 × 8%

= 6% + 12%

= 18%

So abnormal return = 19% - 18% = 1%

In case of Second Investment Advisor:

The return is 16%

And, the expected return equal to

= 6% + 1 × (14% - 6%)

= 6% + 1 × 8%

= 6% + 8%

= 14%

So abnormal return = 16% - 18% = 2%

So, Second Investment Advisor should be accepted as it has high abnormal return then first investment Advisor

c. In case of First Investment Advisor:

The return is 19%

And, the expected return equal to

= 3% + 1.5 × (15% - 3%)

= 3% + 1.5 × 12%

= 3% + 18%

= 21%

So abnormal return = 19% - 21% = -2%

In case of Second Investment Advisor:

The return is 16%

And, the expected return equal to

= 3% + 1 × (15% - 3%)

= 3% + 1 × 12%

= 3% + 12%

= 15%

So abnormal return = 16% - 15% = 1%

So, Second Investment Advisor should be accepted as it has high abnormal return then first investment Advisor

answer: i'd say the answer is d because the information system is the human already doing the activity.
