USE THE FOLLOWING INFORMATION FOR THE NEXT FOUR PROBLEMS

Stock Rit Rmt ai Beta
A 10.6 15 0 0.8
Z 9.8 8.0 0 1.1

Rit = return for stock i during period t
Rmt = return for the aggregate market during period t

1. What is the abnormal rate of return for Stock A during period t using only the aggregate market return (ignore differential systematic risk)?

2. What is the abnormal rate of return for Stock Z during period t using only the aggregate market return (ignore differential systematic risk)?

3. What is the abnormal rate of return for Stock A when you consider its systematic risk measure (beta)?

4. What is the abnormal rate of return for Stock Z when you consider its systematic risk measure (beta)?

#### Solution Preview
