3、ks using a divisor of 100 is A)1.2 B)1200 C)490 D)4900 E)49 Answer: C   Difficulty: Moderate      Rationale: The sum of the value of the three stocks divided by 100 is 490:

4、60;($40 x 200) + ($70 x 500) + ($10 x 600) /100 = 4903.Assume at these prices the value-weighted index constructed with the three stocks is 490. What would the index be if stock B is split 2 for 1 and stock C 4 for 1? A)265 B)430 C)355

5、 D)490 E)1000 Answer: D Difficulty: Moderate Rationale: Value-weighted indexes are not affected by stock splits.4.An investor purchases one municipal and one corporate bond that pay rates of return of 8% and 10%, respectively. If the investor is in the 20% marginal tax bracket, his or her after tax

6、rates of return on the municipal and corporate bonds would be _ and _, respectively. A)8% and 10% B)8% and 8% C)6.4% and 8% D)6.4% and 10% E)10% and 10% Answer: B Difficulty: Moderate Rationale: rc = 0.10(1 - 0.20) = 0.08, or 8%; rm = 0.08(1 - 0) = 8%.5.A 5.5% 20-year municipal bond is currently pri

7、ced to yield 7.2%. For a taxpayer in the 33% marginal tax bracket, this bond would offer an equivalent taxable yield of: A)8.20%. B)10.75%. C)11.40%. D)4.82%. E)none of the above. Answer: B Difficulty: Moderate Rationale: 0.072 = rm (1-t); 0.072 = rm / (0.67); rm = 0.1075 = 10.75%6.In order for you

8、to be indifferent between the after tax returns on a corporate bond paying 8.5% and a tax-exempt municipal bond paying 6.12%, what would your tax bracket need to be? A)33% B)72% C)15% D)28% E)Cannot tell from the information given .0612 = .085(1-t); (1-t) = 0.72; t = .287.Suppose an investor is cons

9、idering a corporate bond with a 7.17% before-tax yield and a municipal bond with a 5.93% before-tax yield. At what marginal tax rate would the investor be indifferent between investing in the corporate and investing in the muni? A)15.4% B)23.7% C)39.5% D)17.3% E)12.4% tm = 1 - (5.93%/7.17%) = 17.29%

10、Use the following to answer questions 8 to 9:8.Based on the information given, for a price-weighted index of the three stocks calculate: A)the rate of return for the first period (t=0 to t=1). B)the value of the divisor in the second period (t=2). Assume that Stock A had a 2-1 split during this peri

11、od. C)the rate of return for the second period (t=1 to t=2). A. The price-weighted index at time 0 is (70 + 85 + 105)/3 = 86.67. The price-weighted index at time 1 is (72 + 81 + 98)/3 = 83.67. The return on the index is 83.67/86.67 - 1 = -3.46%. B. The divisor must change to reflect the stock split.

12、 Because nothing else fundamentally changed, the value of the index should remain 83.67. So the new divisor is (36 + 81 + 98)/83.67 = 2.57. The index value is (36 + 81 + 98)/2.57 = 83.67. C. The rate of return for the second period is 83.67/83.67 - 1 = 0.00%9.Based on the information given for the t

13、hree stocks, calculate the first-period rates of return (from t=0 to t=1) on A)a market-value-weighted index. B)an equally-weighted index. C)a geometric index. A. The total market value at time 0 is $70 * 200 + $85 * 500 + $105 * 300 = $88,000. The total market value at time 1 is $72 * 200 + $81 * 5

14、00 + $98 * 300 = $84,300. The return is $84,300/$88,000 - 1 = -4.20%. B. The return on Stock A for the first period is $72/$70 - 1 = 2.86%. The return on Stock B for the first period is $81/$85 - 1 = -4.71%. The return on Stock C for the first period is $98/$105 - 1 = -6.67%. The return on an equall

15、y weighted index of the three stocks is (2.86% - 4.71% - 6.67%)/3 = -2.84%C. The geometric average return is (1+.0286)(1-.0471)(1-.0667)(1/3)-1 = (1.0286)(0.9529)(0.9333)0.3333 -1 = -2.92%10.
