(Computing the standard deviation for a portfolio of two risky investments) Mary Guilott recently graduated from college and is evaluating an investment in two companies' common stock. She has collected the following information about the common stock of Firm A and Firm B: a. If Mary decides to invest 10 percent of her money in Firm A's common stock and 90 percent in Firm B's common stock, what is the expected rate of return and the standard deviation of the portfolio return? b. If Mary decides to invest 90 percent of her money in Firm A's common stock and 10 percent in Firm B's common stock, what is the expected rate of return and the standard deviation of the portfolio return? c. Recompute your responses to both questions a and b, where the correlation between the two firms' stock returns is -0.50. d. Summarize what your analvsis tells vou about portfolio risk when combinina risky assets in a portfolio. a.
