Compute the expected return, standard deviation, beta, and nonsystematic standard deviation of the portfolio. 4. Assume that the total market value of an initial portfolio is $300,000. Suppose that the owner of this portfolio wishes to decrease risk by reducing the allocation to the risky portfolio from y = 0.7 to y = 0.56. How do you reallocate your risky portfolio? 5.

Suppose that there are many stocks in the security market and that the characteristics of stocks A and B are given as follows: Stock Expected Return Standard Deviation 10% 5% 15 10 Correlation = -1 Suppose that it is possible to borrow at the risk-free rate, r. What must be the value of the risk-free rate? (Hint: Think about constructing a risk-free portfolio from stocks A and B.)
