1、CHAPTER 1: THE INVESTMENT ENVIRONMENT PROBLEM SETS 1. Ultimately, it is true that real assets determine the material well being of an economy. Nevertheless, individuals can benefit when financial engineering creates new products that allow them to manage their portfolios of financial assets more eff

2、iciently. Because bundling and unbundling creates financial products with new properties and sensitivities to various sources of risk, it allows investors to hedge particular sources of risk more efficiently. 2. Securitization requires access to a large number of potential investors. To attract thes

3、e investors, the capital market needs: 1. a safe system of business laws and low probability of confiscatory taxation/regulation; 2. a well-developed investment banking industry; 3. a well-developed system of brokerage and financial transactions, and; 4. well-developed media, particularly financial

4、reporting. These characteristics are found in (indeed make for) a well-developed financial market. 3. Securitization leads to disintermediation; that is, securitization provides a means for market participants to bypass intermediaries. For example, mortgage-backed securities channel funds to the hou

5、sing market without requiring that banks or thrift institutions make loans from their own portfolios. As securitization progresses, financial intermediaries must increase other activities such as providing short-term liquidity to consumers and small business, and financial services. 4. Financial ass

6、ets make it easy for large firms to raise the capital needed to finance their investments in real assets. If Ford, for example, could not issue stocks or bonds to the general public, it would have a far more difficult time raising capital. Contraction of the supply of financial assets would make fin

7、ancing more difficult, thereby increasing the cost of capital. A higher cost of capital results in less investment and lower real growth. 5. Even if the firm does not need to issue stock in any particular year, the stock market is still important to the financial manager. The stock price provides im

8、portant information about how the market values the firm's investment projects. For example, if the stock price rises considerably, managers might conclude that the market believes the firm's future prospects are bright. This might be a useful signal to the firm to proceed with an investment

9、 such as an expansion of the firm's business. In addition, shares that can be traded in the secondary market are more attractive to initial investors since they know that they will be able to sell their shares. This in turn makes investors more willing to buy shares in a primary offering, and th

10、us improves the terms on which firms can raise money in the equity market. 6. a. No. The increase in price did not add to the productive capacity of the economy. b. Yes, the value of the equity held in these assets has increased. c. Future homeowners as a whole are worse off, since mortgage liabilit

11、ies have also increased. In addition, this housing price bubble will eventually burst and society as a whole (and most likely taxpayers) will endure the damage. 7. a. The bank loan is a financial liability for Lanni. (Lanni's IOU is the bank's financial asset.) The cash Lanni receives is a f

12、inancial asset. The new financial asset created is Lanni's promissory note (that is, Lannis IOU to the bank). b. Lanni transfers financial assets (cash) to the software developers. In return, Lanni gets a real asset, the completed software. No financial assets are created or destroyed; cash is s

13、imply transferred from one party to another. c. Lanni gives the real asset (the software) to Microsoft in exchange for a financial asset, 1,500 shares of Microsoft stock. If Microsoft issues new shares in order to pay Lanni, then this would represent the creation of new financial assets. d. Lanni ex

14、changes one financial asset (1,500 shares of stock) for another ($120,000). Lanni gives a financial asset ($50,000 cash) to the bank and gets back another financial asset (its IOU). The loan is "destroyed" in the transaction, since it is retired when paid off and no longer exists. 8. a. As

17、al $150,000 Total $150,000 Ratio of real assets to total assets = $30,000/$150,000 = 0.20 Conclusion: when the firm starts up and raises working capital, it is characterized by a low ratio of real assets to total assets. When it is in full production, it has a high ratio of real assets to total asse

18、ts. When the project "shuts down" and the firm sells it off for cash, financial assets once again replace real assets. 9. For commercial banks, the ratio is: $140.1/$11,895.1 = 0.0118 For non-financial firms, the ratio is: $12,538/$26,572 = 0.4719 The difference should be expected primaril

19、y because the bulk of the business of financial institutions is to make loans; which are financial assets for financial institutions. 10. a. Primary-market transaction b. Derivative assets c. Investors who wish to hold gold without the complication and cost of physical storage. 11. a. A fixed salary

20、 means that compensation is (at least in the short run) independent of the firm's success. This salary structure does not tie the managers immediate compensation to the success of the firm. However, the manager might view this as the safest compensation structure and therefore value it more high

21、ly. b. A salary that is paid in the form of stock in the firm means that the manager earns the most when the shareholders wealth is maximized. Five years of vesting helps align the interests of the employee with the long-term performance of the firm. This structure is therefore most likely to align

22、the interests of managers and shareholders. If stock compensation is overdone, however, the manager might view it as overly risky since the managers career is already linked to the firm, and this undiversified exposure would be exacerbated with a large stock position in the firm. c. A profit-linked

23、salary creates great incentives for managers to contribute to the firms success. However, a manager whose salary is tied to short-term profits will be risk seeking, especially if these short-term profits determine salary or if the compensation structure does not bear the full cost of the projects ri

24、sks. Shareholders, in contrast, bear the losses as well as the gains on the project, and might be less willing to assume that risk. 12. Even if an individual shareholder could monitor and improve managers performance, and thereby increase the value of the firm, the payoff would be small, since the o

25、wnership share in a large corporation would be very small. For example, if you own $10,000 of Ford stock and can increase the value of the firm by 5%, a very ambitious goal, you benefit by only: 0.05 × $10,000 = $500 In contrast, a bank that has a multimillion-dollar loan outstanding to the fir

26、m has a big stake in making sure that the firm can repay the loan. It is clearly worthwhile for the bank to spend considerable resources to monitor the firm. 13. Mutual funds accept funds from small investors and invest, on behalf of these investors, in the national and international securities mark

27、ets. Pension funds accept funds and then invest, on behalf of current and future retirees, thereby channeling funds from one sector of the economy to another. Venture capital firms pool the funds of private investors and invest in start-up firms. Banks accept deposits from customers and loan those f

28、unds to businesses, or use the funds to buy securities of large corporations. 14. Treasury bills serve a purpose for investors who prefer a low-risk investment. The lower average rate of return compared to stocks is the price investors pay for predictability of investment performance and portfolio v

29、alue. 15. With a “top-down” investing style, you focus on asset allocation or the broad composition of the entire portfolio, which is the major determinant of overall performance. Moreover, top-down management is the natural way to establish a portfolio with a level of risk consistent with your risk

30、 tolerance. The disadvantage of an exclusive emphasis on top-down issues is that you may forfeit the potential high returns that could result from identifying and concentrating in undervalued securities or sectors of the market. With a “bottom-up” investing style, you try to benefit from identifying

31、 undervalued securities. The disadvantage is that you tend to overlook the overall composition of your portfolio, which may result in a non-diversified portfolio or a portfolio with a risk level inconsistent with your level of risk tolerance. In addition, this technique tends to require more active

32、management, thus generating more transaction costs. Finally, your analysis may be incorrect, in which case you will have fruitlessly expended effort and money attempting to beat a simple buy-and-hold strategy. 16. You should be skeptical. If the author actually knows how to achieve such returns, one

33、 must question why the author would then be so ready to sell the secret to others. Financial markets are very competitive; one of the implications of this fact is that riches do not come easily. High expected returns require bearing some risk, and obvious bargains are few and far between. Odds are t

34、hat the only one getting rich from the book is its author. 17. Financial assets provide for a means to acquire real assets as well as an expansion of these real assets. Financial assets provide a measure of liquidity to real assets and allow for investors to more effectively reduce risk through dive

35、rsification. 18. Allowing traders to share in the profits increases the traders willingness to assume risk. Traders will share in the upside potential directly but only in the downside indirectly (poor performance = potential job loss). Shareholders, by contrast, are affected directly by both the up

36、side and downside potential of risk. 19. Answers may vary, however, students should touch on the following: increased transparency, regulations to promote capital adequacy by increasing the frequency of gain or loss settlement, incentives to discourage excessive risk taking, and the promotion of mor

37、e accurate and unbiased risk assessment. CHAPTER 2: ASSET CLASSES AND FINANCIAL INSTRUMENTS PROBLEM SETS 1. Preferred stock is like long-term debt in that it typically promises a fixed payment each year. In this way, it is a perpetuity. Preferred stock is also like long-term debt in that it does not

38、 give the holder voting rights in the firm. Preferred stock is like equity in that the firm is under no contractual obligation to make the preferred stock dividend payments. Failure to make payments does not set off corporate bankruptcy. With respect to the priority of claims to the assets of the fi

39、rm in the event of corporate bankruptcy, preferred stock has a higher priority than common equity but a lower priority than bonds. 2. Money market securities are called “cash equivalents” because of their great liquidity. The prices of money market securities are very stable, and they can be convert

40、ed to cash (i.e., sold) on very short notice and with very low transaction costs. 3. (a) A repurchase agreement is an agreement whereby the seller of a security agrees to “repurchase” it from the buyer on an agreed upon date at an agreed upon price. Repos are typically used by securities dealers as

41、a means for obtaining funds to purchase securities. 4. The spread will widen. Deterioration of the economy increases credit risk, that is, the likelihood of default. Investors will demand a greater premium on debt securities subject to default risk. 5. Corp. Bonds Preferred Stock Common Stock Voting

42、 Rights (Typically) Yes Contractual Obligation Yes Perpetual Payments Yes Yes Accumulated Dividends Yes Fixed Payments (Typically) Yes Yes Payment Preference First Second Third 6. Municipal Bond interest is tax-exempt. When facing higher marginal tax rates, a high-income investor would be more incli

43、ned to pick tax-exempt securities. 7. a. You would have to pay the asked price of: 86:14 = 86.43750% of par = $864.375 b. The coupon rate is 3.5% implying coupon payments of $35.00 annually or, more precisely, $17.50 semiannually. c. Current yield = Annual coupon income/price = $35.00/$864.375 = 0.0

44、405 = 4.05% 8. P = $10,000/1.02 = $9,803.92 9. The total before-tax income is $4. After the 70% exclusion for preferred stock dividends, the taxable income is: 0.30 × $4 = $1.20 Therefore, taxes are: 0.30 × $1.20 = $0.36 After-tax income is: $4.00 $0.36 = $3.64 Rate of return is: $3.64/$40

45、.00 = 9.10% 10. a. You could buy: $5,000/$67.32 = 74.27 shares b. Your annual dividend income would be: 74.27 × $1.52 = $112.89 c. The price-to-earnings ratio is 11 and the price is $67.32. Therefore: $67.32/Earnings per share = 11 Earnings per share = $6.12 d. General Dynamics closed today at

46、$67.32, which was $0.47 higher than yesterdays price. Yesterdays closing price was: $66.85 11. a. At t = 0, the value of the index is: (90 + 50 + 100)/3 = 80 At t = 1, the value of the index is: (95 + 45 + 110)/3 = 83.333 The rate of return is: (83.333/80) 1 = 4.17% b. In the absence of a split, Sto

47、ck C would sell for 110, so the value of the index would be: 250/3 = 83.333 After the split, Stock C sells for 55. Therefore, we need to find the divisor (d) such that: 83.333 = (95 + 45 + 55)/d d = 2.340 c. The return is zero. The index remains unchanged because the return for each stock separately

48、 equals zero. 12. a. Total market value at t = 0 is: ($9,000 + $10,000 + $20,000) = $39,000 Total market value at t = 1 is: ($9,500 + $9,000 + $22,000) = $40,500 Rate of return = ($40,500/$39,000) 1 = 3.85% b. The return on each stock is as follows: rA = (95/90) 1 = 0.0556 rB = (45/50) 1 = 0.10 rC =

49、 (110/100) 1 = 0.10 The equally-weighted average is: 0.0556 + (-0.10) + 0.10/3 = 0.0185 = 1.85% 13. The after-tax yield on the corporate bonds is: 0.09 × (1 0.30) = 0.0630 = 6.30% Therefore, municipals must offer at least 6.30% yields. 14. Equation (2.2) shows that the equivalent taxable yield

50、is: r = rm /(1 t) a. 4.00% b. 4.44% c. 5.00% d. 5.71% 15. In an equally-weighted index fund, each stock is given equal weight regardless of its market capitalization. Smaller cap stocks will have the same weight as larger cap stocks. The challenges are as follows: Given equal weights placed to small

51、er cap and larger cap, equalweighted indices (EWI) will tend to be more volatile than their market-capitalization counterparts; It follows that EWIs are not good reflectors of the broad market which they represent; EWIs underplay the economic importance of larger companies; Turnover rates will tend

52、to be higher, as an EWI must be rebalanced back to its original target. By design, many of the transactions would be among the smaller, less-liquid stocks. 16. a. The higher coupon bond. b. The call with the lower exercise price. c. The put on the lower priced stock. 17. a. You bought the contract w

53、hen the futures price was $3.835 (see Figure 2.10). The contract closes at a price of $3.875, which is $0.04 more than the original futures price. The contract multiplier is 5000. Therefore, the gain will be: $0.04 × 5000 = $200.00 b. Open interest is 177,561 contracts. 18. a. Since the stock p

54、rice exceeds the exercise price, you exercise the call. The payoff on the option will be: $21.75 $21 = $0.75 The cost was originally $0.64, so the profit is: $0.75 $0.64 = $0.11 b. If the call has an exercise price of $22, you would not exercise for any stock price of $22 or less. The loss on the ca

55、ll would be the initial cost: $0.30 c. Since the stock price is less than the exercise price, you will exercise the put. The payoff on the option will be: $22 $21.75 = $0.25 The option originally cost $1.63 so the profit is: $0.25 $1.63 = $1.38 19. There is always a possibility that the option will

56、be in-the-money at some time prior to expiration. Investors will pay something for this possibility of a positive payoff. 20. Value of call at expiration Initial Cost Profit a. 0 4 -4 b. 0 4 -4 c. 0 4 -4 d. 5 4 1 e. 10 4 6 Value of put at expiration Initial Cost Profit a. 10 6 4 b. 5 6 -1 c. 0 6 -6 d. 0 6 -6 e. 0 6 -6 21. A put option conveys the right to sell the underlying asset at the exercise price. A short position in a futures contract carries an obligation to sell the underlying asset at the futures price. 22. A call option conveys the right to buy the underlying asset at the
