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 alternstives being considered have widely differeing expected returns. Calculate the missing CV's 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.

-23 RISK AND RETURN Assume that you res job as a financial planner with Merrill Finch Inc you recently graduated with a major in finance. You just landed a ment is to invest $100,000 for a client. Becau inch Inc., a large financial services corporation. Your first assign- t. Because the funds are to be invested in a business at the end of 1 year, you have been instructed to plan for 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 associ outcomes.

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 car 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: ne of the economy? Do T-bills promise a com
