The price-weighted index constructed with the three stocks is A) 30 B) 40 C) 50 D) 60 E) 70 Answer: B Difficulty: Easy Rationale: ($40 + $70 + $10)/3 = $40. 2. The value-weighted index constr
3、ucted with the three stocks using a divisor of 100 is A) 1.2 B) 1200 C) 490 D) 4900 E) 49 Answer:CDifficulty:ModerateRationale:Thesumofthevalueofthethreestocksdividedby100is490:($40x200)+($70x500)+($10x600)/100=490 3. Assume at these prices the value-weighted index constructed with the three stocks
4、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 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 retur
5、n of 8% and 10%, respectively. If the investor is in the 20% marginal tax bracket, his or her after tax 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 Rationa
6、le: 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 priced 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. Answe
7、r: B Difficulty: Moderate Rationale: 0.072 = rm (1-t); 0.072 = rm / (0.67); rm = 0.1075 = 10.75%6. In order for you 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) 1
8、5% D) 28% E) Cannot tell from the information given .0612 = .085(1-t); (1-t) = 0.72; t = .287. Suppose an investor is considering 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 inv
9、esting 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%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 firs
10、t 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 period. 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 (
11、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. 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
12、+ 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 three 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.
13、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 * 500 + $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 f
14、or 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 equally 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)(

16、ow from the broker? A) $6,000 B) $4,000 C) $7,700 D) $7,000 E) $6,300 Answer: E Difficulty: Moderate Rationale: 200 shares * $70/share * (1-0.55) = $14,000 * (0.45) = $6,300. 2. You sold short 200 shares of common stock at $60 per share. The initial margin is 60%. Your initial investment was A) $4,8
17、00. B) $12,000. C) $5,600. D) $7,200. E) none of the above. Answer: D Difficulty: Moderate Rationale: 200 shares * $60/share * 0.60 = $12,000 * 0.60 = $7,2003. You purchased 100 shares of ABC common stock on margin at $70 per share. Assume the initial margin is 50% and the maintenance margin is 30%.
18、 Below what stock price level would you get a margin call? Assume the stock pays no dividend; ignore interest on margin. A) $21 B) $50 C) $49 D) $80 E) none of the above Answer: B Difficulty: Difficult Rationale: 100 shares * $70 * .5 = $7,000 * 0.5 = $3,500 (loan amount); 0.30 = (100P - $3,500)/100
19、P; 30P = 100P - $3,500; -70P = -$3,500; P = $50.4. You purchased 100 shares of common stock on margin at $45 per share. Assume the initial margin is 50% and the stock pays no dividend. What would the maintenance margin be if a margin call is made at a stock price of $30? Ignore interest on margin. A
20、) 0.33 B) 0.55 C) 0.43 D) 0.23 E) 0.25 Answer: E Difficulty: Difficult Rationale: 100 shares * $45/share * 0.5 = $4,500 * 0.5 = $2,250 (loan amount); X = 100($30) - $2,250/100($30); X = 0.25. 5. You purchased 300 shares of common stock on margin for $60 per share. The initial margin is 60% and the s

A) 25% B) -33% C) 44% D) -42% E) 54% Answer: D Difficulty: Difficult Rationale: 300($60)(0.60) = $10,800 investment; 300($60) = $18,000 *(0.40) = $7,200 loan; Proceeds after se
22、lling stock and repaying loan: $13,500 - $7,200 = $6,300; Return = ($6,300 - $10,800)/$10,800 = - 41.67%. 6. Assume you sell short 100 shares of common stock at $45 per share, with initial margin at 50%. What would be your rate of return if you repurchase the stock at $40/share? The stock paid no di

A) 20% B) 25% C) 22% D) 77% E) none of the above Answer: C Difficulty: Moderate Rationale: Profit on stock = ($45 - $40) * 100 = $500, $500/$2,250 (initial investment) = 22.22%7. Yo

A) 100 shares B) 200 shares C) 50 shares D) 500 shares E) 25 shares Answer: A Difficulty: ModerateRationale: .5 = (Q
25、 * $60)-$3,000 / (Q * $60); $30Q = $60Q-$3,000; $30Q = $3,000; Q=100.8. You buy 300 shares of Qualitycorp for $30 per share and deposit initial margin of 50%. The next day Qualitycorps price drops to $25 per share. What is your actual margin? A) 50% B) 40% C) 33% D) 60% E) 25% Answer: B Difficulty:
26、Moderate Rationale: AM = 300 ($25) - .5 (300) ($30) / 300 ($25) = .409. You sold short 100 shares of common stock at $45 per share. The initial margin is 50%. Your initial investment was A) $4,800. B) $12,000. C) $2,250. D) $7,200. E) none of the above. Answer: C Difficulty: Moderate Rationale: 100
