Suppose we have the following returns for large-company stocks and Treasury bills over a six-year period: |
Year | Large Company | US Treasury Bill |
1 | 3.69% | 4.75% |
2 | 14.48 | 3.59 |
3 | 19.27 | 4.18 |
4 | –14.41 | 5.91 |
5 | –31.90 | 5.32 |
6 | 37.51 | 6.41 |
a. |
Calculate the arithmetic average returns for large-company stocks and T-bills over this period. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) |
b. | Calculate the standard deviation of the returns for large-company stocks and T-bills over this period. (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) |
c-1. | Calculate the observed risk premium in each year for the large-company stocks versus the T-bills. What was the average risk premium over this period? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) |
c-2. | Calculate the observed risk premium in each year for the large-company stocks versus the T-bills. What was the standard deviation of the risk premium over this period? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) |
