Answer:
Consider the following calculations and explanations
Step-by-step explanation:
For every 1 % change in market portfolio, the retirement portfolio would change by 1.75% .
a. If the value of the market portfolio rises by 8%, then the value of your father's retirement fund should increase by 8%*1.75% = 14%
b. If the value of the market portfolio drops by 8%, then the value of your father's retirement fund should decrease by 14%
c. Your father's retirement portfolio is more risky than the market portfolio because your father's retirement portfolio beta, it's systematic risk, is greater than the market's portfolio beta. Beta of the portfolio generally denotes the volatitlity in comparision to the market. If the beta is more , it is more volatile and risky.
