Under the assumptions of Modigliani and Miller’s original paper, a firm’s stock price will be maximized at 100% (debt, equity) . Signaling theory implies that a firm with extremely favorable prospects will be more likely to issue (stock, debt) to fund any new projects. When a firm announces a new stock offering, the price of its stock will usually (increase, decrease)   . When information is (asymetric, symetric)   , managers have more information about a firm’s prospects than investors do.

Drugal Brewing Co. currently has no debt in its capital structure, but it is considering using some debt and reducing its outstanding equity. The firm’s unlevered beta is 1.20, and its cost of equity is 11.40%. Because the firm has no debt in its capital structure, its weighted average cost of capital (WACC) also equals 11.40%. The risk-free rate of interest (rRFrRF) is 3%, and the market risk premium (RP) is 7%. Drugal Brewing Co.’s marginal tax rate is 35%.

Drugal Brewing Co. is examining how different levels of debt will affect its costs of debt and equity, as well as its WACC. The firm has collected the financial information that follows to analyze its weighted average cost of capital (WACC). Complete the following table.

Assume that you recently graduated and you just landed a job as a financial planner with the Cleveland Clinic. Your first assignment is to invest $100,000. Because the funds are to be invested at the end of one year, you have been instructed to plan for a one-year holding period. Further, your boss has restricted you to the following investment alternatives, shown with their probabilities and associated outcomes.

Barney Smith Investment Advisors recently issued estimates for the state of the economy and the rate of return on each state of the economy. Alta Industries, Inc. is an electronics firm; Repo Men Inc. collects past due debts; and American Foam manufactures mattresses and various other foam products. Barney Smith also maintains an "index fund" which owns a market-weighted fraction of all publicly traded stocks; you can invest in that fund and thus obtain average stock market results. Given the situation as described, answer the following questions using Excel (Please Show Excel Formulas).   

a. Calculate the expected rate of return on each alternative.

b. Calculate the standard deviation of returns on each alternative.                                               

c. Calculate the coefficient of variation on each alternative.                        

d. Calculate the beta on each alternative.                                                                                            

e. Do the SD, CV, and beta produce the same risk ranking? Why or why not?
