    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?

    2013 20 11 15
    Assume that the risk-free rate is 6% and the market risk premium is 5%.
    a. What are the betas of Stocks X and Y?
    b. What are the required rates of return on Stock X and Y?
    c. What is the required rate of return on a portfolio consisting of 80% of Stock X and 20% of Stock Y?

    3. Two-Asset Portfolio
    Stock A has an expected return of 12% and a standard deviation of 40%. Stock B has an expected return of 18% and a standard deviation of 60%. The correlation coefficient between Stock A and B is 0.2. What are the expected return and standard deviation of a portfolio invested 30% in Stock A and 70% in Stock B?
