Solutions to Questions and Problems
NOTE: All end of chapter problems were solved using a spreadsheet. Many problems require
multiple steps. Due to space and readability constraints, when these intermediate steps are
included in this solutions manual, rounding may appear to have occurred. However, the final
answer for each problem is found without rounding during any step in the problem.
1.
The return of any asset is the increase in price, plus any dividends or cash flows, all divided
by the initial price. The return of this stock is:
R = [($102 – 91) + 2.40] / $91 = .1473 or 14.73%
8.
We will calculate the sum of the returns for each asset and the observed risk premium first.
Doing so, we get:
