Chapter 8 Risk and Rates of Return INTEGRATED CASE MERRILL FINCH INC. 8-23 RISK AND RETURN Assume that you recently graduated with a major in finance. You just landed a job as a financial planner with Merrill Finch Inc, a large financial services corporation. Your first assign ment is to invest $100,000 for a client. Because the funds are to be invested in a business at the end of 1 year you have been instructed to plan for a 1-year holding period. Further, your boss has restricted you to the investment alternatives in the following table, shown with their probabilities and associated outcomes. (For now, disregard the items at the bottom of the data; you will fill in the blanks later.) Returns on Alternative Investments 5.51 5.8 Estimated Rate of Return State of the High U.S. Market Two-Stock Economy Probability T-Bills Tech Collections Rubber Portfolio Portfolio Recession 0.1 3.096 129.596) 24.5% 3:59 (19.596) (2.5%) Below average 0.2 3,0 (9.5) 10.5 (165) Average 0.4 3.0 12.5 (1.0) 0.5 7.5 Above average 0.2 3.0 27.5 (5.0) 38.5 22.5 Boom 0.1 3.0 42.5 (2000) 23.5 355 113 1.2% 7.3% 8.0% 0.0 11.2 18.8 15.2 4.6 CV 9,8 2.6 19 0.8 Sharpe ratio -0.16 0.54 b -0.50 0.88 Note: "The estimated returns of U.S. Rubber do not always move in the same direction as the overall economy. For example, when the economy is below average consumers purchase fewer tires than they would if the economy was stronger. However, if the economy is in a flat-out recession, a large number of consumers who were planning to purchase a new cat may choose to wait and instead purchase new tires for the car they currently own. Under these circumstances, we would expect U.S. Rubber's stock price to be higher if there is a recession than if the economy is just below average Merrill Finch's economic forecasting staff has developed probability estimates for the state of the economy, and its security analysts developed a sophisticated computer program to estimate the rate of return on each alternative under each state of the economy. High Tech Inc. is an electronics firm, Collections Inc. collects past-due debts, and U.S. Rubber manufactures tires and various other rubber and plastics products. Merrill Finch also maintains a "market portfolio that owns a market-weighted fraction of all publicly traded stocks, you can invest in that portfolio and thus obtain average stock market results. Given the situation described, answer the following questions: art 3 Financial Assets e. 3. Draw a graph that shows roughly the shape of the probability distributions for High Tech, U.S. Rubber, and T-bills. d. Suppose you suddenly remembered that the coefficient of variation (CV) is generally regarded as being a better measure of stand-alone risk than the standard deviation when the alternatives being considered have widely differing expected returns. Calculate the missing CVs, and fill in the blanks on the row for CV in the table. Does the CV produce the same risk rankings as the standard deviation? Explain Someone mentioned that you might also want to calculate the Sharpe ratio as a measure of stand- alone risk. Calculate the missing ratios and fill in the blanks on the row for the Sharpe ratio in the table. Briefly explain what the Sharpe ratio actually measures. f Suppose you created a two-stock portfolio by investing $50,000 in High Tech and $50,000 in Collections 1. Calculate the expected return (t), the standard deviation (r), the coefficient of variation (CV,), and the Sharpe ratio for this portfolio, and fill in the appropriate blanks in the table. 2. How does the riskiness of this two-stock portfolio compare with the riskiness of the individual stocks if they were held in isolation? g Suppose an investor starts with a portfolio consisting of one randomly selected stock. 1. What would happen to the riskiness and to the expected return of the portfolio as more randomly selected stocks were added to the portfolio? 2. What is the implication for investors? Draw a graph of the two portfolios to illustrate your h. 1. Should the effects of a portfolio impact the way investors think about the riskiness of individual stocks? 2. If you decided to hold a one-stock portfolio (and consequently were exposed to more risk tham diversified investors), could you expect to be compensated for all of your risk; that is, could you
