- An analyst has modeled the stock of a company using the Fama-French three-factor model. The market return is 10%, the return on the SMB portfolio (rSMB) is 3.2%, and the return on the HML portfolio (rHML) is 4.8%.

Stock B has an expected return of 18% and a standard deviation of 60%. The correlation coefficient between Stocks A and B is 0.2.

Your objective is to build up as much capital as you can over the next 15 to 20 years, and you’re willing to tolerate a “good deal’’ of risk. What types of stocks (blue chips, income stocks, and so on) do you think you’d be most interested in, and why? Select at least three types of stocks and briefly explain the rationale for selecting each. Would your selections change if you were dealing with a smaller amount of money—say, only $50,000?

- 2B) You have $600,000 to invest in the stock market. Suppose you invested one-third of your wealth in stock Q and the rest in stock L. These stocks have the following characteristics: Stock Q has an expected return of 10% and a standard deviation of 7%. Stock L has an expected return of 18% and a standard deviation of 11%. Determine the expected return and standard deviation on a portfolio of stocks Q and L, when the two stocks are uncorrelated and when they are negatively perfectly correlated. Interpret and compare your answers in these two cases.arrow_forwardStocks A and B have the following data. Assuming the stock market is efficient and the stocks are in equilibrium, which of the following statements is CORRECT? A B Price $25 $40 Expected growth 7% 9% Expected return 10% 12% a. The two stocks could not be in equilibrium with the numbers given in the question. b. A's expected dividend is $0.50. c. B's expected dividend is $0.75. d. A's expected dividend is $0.75 and B's expected dividend is $1.20. e. The two stocks should have the same expected dividend.arrow_forwardSuppose that three stocks (A, B, and C} and two common risk factors (1 and 2) have the following relationship: E(RA) = (1.1)A1 + (0.8)A2 E(RB) = (0.7)A1 + (0.6)A2 E(RC) = (0.3)A1 + (0.4)A2 a. If A1 = 4 percent and A2 = 2 percent, what are the prices expected next year for each of the stocks? Assume that all three stocks currently sell for $30 and will not pay a dividend in the next year. b. Suppose that you know that next year the prices for Stocks A, B, and C will actually be $31.50, $35.00, and $30.50. Create and demonstrate a riskless, arbitrage investment to take advantage of these mispriced securities. What is the profit from your investment? You may assume that you can use the proceeds from any necessary short sale.

- Assume you have invested in two other stocks: Stock A has a beta of 1.20 and Stock B has a beta of 0.8. Rf= 2% and Rm = 12%. Using CAPM, what are the expected returns for each stock? Return of stock = Risk free rate + beta ( market rate of return - risk free rate of return) Return of Stock A = 2% + 1.20 (12% - 2%) = 2.12% Return of Stock B = 2% + 0.80 (12% - 2%) = 2.08% What is the expected return of an equally weighted portfolio of these two stocks? Weight of stock A = 0.50 Weight of Stock B = 0.50 Expected return = (Return of Stock A * weight of Stock A) + (Return of Stock B * weight of stock B) = (2.12 * 0.50) + (2.08*0.50) = 1.06 + 1.04 = 3% What is the beta of an equally weighted portfolio of these two stocks? Beta of portfolio = (Beta of Stock A * weight of stock A) + (Beta of Stock B * weight of Stock B) = (1.20*0.50) + (0.80*0.50) = 0.60 + 0.40 = 1 Beta of portfolio = 1 (iv) Sketch the SML to represent the…arrow_forwardYou have recently received $400,000 and you are considering investing $250,000 in the WIG and the remainder in TJH.
