2. Required Rate of Return

AA Industries stock has a beta of 0.8. The risk-free rate is 4% and the expected return on the market is 12%. What is the required rate of return on AA's stock?

10. Portfolio Required Return

Suppose you manage a $4 million fund that consists of four stocks with the following investments:

Stock Investment Beta______________

A $ 400,000 1.50

B 600,000 -0.50

C 1,000,000 1.25

D 2,000,000 0.75

If the market's required rate of return is 14% and the risk-free rate is 6%, what is the fund's required rate of return?

13. Historical Realized Rates of Return

You are considering an investment in either individual stocks or a portfolio of stocks. The two stocks you are researching, stock A and B, have the following historical returns:

Year rA rB_________

2009 -20.00% -5.00%

2010 42.00% 15.00%

2011 20.00% -13.00%

2012 -8.00% 50.00%

2013 25.00% 12.00%

a. Calculate the average rate of return for each stock during the 5-year period.

b. Suppose you had held a portfolio consisting of 50% of Stock A and 50% of Stock B. What would have been the realized rate of return on the portfolio in each year? What would have been the average return o the portfolio during this period?

c. Calculate the standard deviation of returns for each stock and for the portfolio.

d. If you are a risk-averse investor, then, assuming these are your only choices, would you prefer to hold Stock A, Stock B, or the portfolio? Why?

14. Historical Returns: Expected and Required Rates of Return
