Can someone help me with these homework problems, I need to be able to show my work for the questions

1. You bought a stock one year ago for $51.89 per share and sold it today for $58.26 per share. It paid a $1.32 per share dividend today. a. What was your realized return? b. How much of the return came from dividend yield and how much came from capital gain? a. What was your realized return? The realized return was %. (Round to two decimal places.) 2. You bought a stock one year ago for $49.49 per share and sold it today for $45.34 per share. It paid a $1.77 per share dividend today. a. What was your realized return? b. How much of the return came from dividend yield and how much came from capital gain? a. What was your realized return? The realized return was %. (Round to two decimal places.) 3. Consider two local banks. Bank A has 96 loans outstanding, each for $1.0 million, that it expects will be repaid today. Each loan has a 6% probability of default, in which case the bank is not repaid anything. The chance of default is independent across all the loans. Bank B has only one loan of $ 96 million outstanding, which it also expects will be repaid today. It also has a 6 % probability of not being repaid. Which bank faces less risk? Why? (Select the best choice below.) A. The expected payoffs are the same, but Bank A is less risky. I prefer Bank A. B. The expected payoffs are the same, but Bank A is riskier. I prefer Bank B. C. The expected payoff is higher for Bank A, but is riskier. I prefer Bank B. D. In both cases the expected loan payoff is the same: $ 96 million times 0.94 equals $ 90.2 million $96 million0.94=$90.2 million. Consequently, I don't care which bank I own. 4. You are a riskaverse investor considering investing in one of two economies. The expected return and volatility of all stocks in both economies is the same. In the first economy, all stocks move together long in good times all prices go up together, and in bad times they all fall together. In the second economy, stock returns are independent long one stock increasing in price has no effect on the prices of other stocks. Assuming you are riskaverse and you could choose one of the two economies in which to invest, which one would you choose? Explain. (Select the best choice below.) A. A riskaverse investor would choose the economy in which stock returns are independent because risk can be diversified away in a large portfolio. B. A riskaverse investor is indifferent in both cases because he or she faces unpredictable risk. C. A riskaverse investor would prefer the economy in which stock returns are independent because by combining the stocks into a portfolio he or she can get a higher expected return than in the economy in which all stocks move together. D. A riskaverse investor would choose the economy in which stocks move together because the uncertainty is much more predictable, and you have to predict only one thing. 5. What does beta of a stock measure? a) Leverage of a stock b) Amount of systematic risk in a stock c) Liquidity d) Interest rate risk 6. Suppose market risk premium is 5% and the interest free interest rate is 6%, Using this data calculate the expected return of investing in a) Hershey stock b) Starbucks stock c) Auto stock Stock Beta Starbucks 1.20 Hershey .28 Auto 2.14 7. You own three stocks: 600 shares of Apple Computer, 10,000 shares of Cisco Systems, and 5,000 shares of ColgatePalmolive. The current share prices and expected returns of Apple, Cisco, and ColgatePalmolive are, respectively, $ 542 $20, $97and12%, 10%, 8%. a. What are the portfolio weights of the three stocks in your portfolio? b. What is the expected return of your portfolio? c. Suppose the price of Apple stock goes up by $21, Cisco rises by $5, and ColgatePalmolive falls by $ 14 What are the new portfolio weights? d. Assuming the stocks' expected returns remain the same, what is the expected return of the portfolio at the new prices? 8. Suppose Autodesk stock has a beta of 2.20, whereas Costco stock has a beta of .69. If the riskfree interest rate is 6% and the expected return of the market portfolio is 13.0%, what is the expected return of a portfolio that consists of 60% Autodesk stock and 40% Costco stock, according to the CAPM? 9. Unida Systems has 42 million shares outstanding trading for $11 per share. In addition, Unida has $ 117 million in outstanding debt. Suppose Unida's equity cost of capital is 13%, its debt cost of capital is 8 % and the corporate tax rate is 34%. a. What is Unida's unlevered cost of capital? b. What is Unida's aftertax debt cost of capital? c. What is Unida's weighted average cost of capital? 10. You would like to estimate the weighted average cost of capital for a new airline business. Based on its industry asset beta, you have already estimated an unlevered cost of capital for the firm of 8%. However, the new business will be 28% debt financed, and you anticipate its debt cost of capital will be 6% If its corporate tax rate is %31%, what is your estimate of its WACC
