TUTORIAL – SESSION 01CHAPTER 011.Discuss the agency problem.2.Discuss the similarities and differences between real and financial assets.3.Discuss the following ongoing trends as they relate to the field of investments:globalization, financial engineering, securitization, and computer networks. CHAPTER 02Use the following to answer questions 1 to 3:Consider the following three stocks:1. The price-weighted index constructed with the three stocks isA) 30B) 40C) 50D) 60E) 70Answer: B Difficulty: EasyRationale: ($40 + $70 + $10)/3 = $40.2. The value-weighted index constructed with the three stocks using a divisor of100 isA) 1.2B) 1200C) 490D) 4900E) 49Answer:C Difficulty:ModerateRationale:The sum of the value of the three stocks divided by100is490:[($40 x200)+($70x500)+($10x600)]/100=4903. Assume at these prices the value-weighted index constructed with the threestocks is 490. What would the index be if stock B is split 2 for 1 and stock C 4 for 1?A) 265B) 430C) 355D) 490E) 1000Answer: D Difficulty: ModerateRationale: Value-weighted indexes are not affected by stock splits.4. An investor purchases one municipal and one corporate bond that pay rates ofreturn 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: ModerateRationale: 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 inthe 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: ModerateRationale: 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 corporatebond 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 = .(1-t); (1-t) = 0.72; t = .287. Suppose an investor is considering a corporate bond with a 7.17% before-taxyield 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%Use the following to answer questions 8 to 9:8. Based on the information given, for a price-weighted index of the three stockscalculate: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 hada 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-weightedindex at time 1 is (72 + 81 + 98)/3 = 83.67. The return on the index is83.67/86.67 - 1 = -3.46%.B. The divisor must change to reflect the stock split. Because nothing elsefundamentally changed, the value of the index should remain 83.67. So thenew 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 three stocks, calculate the first-periodrates of return (from t=0 to t=1) onA) 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 * 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 StockB for the first period is $81/$85 - 1 = -4.71%. The return on StockC for thefirst period is $98/$105 - 1 = -6.67%. The return on an equally weightedindex 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.Discuss the advantages and disadvantages of common stock ownership, relativeto other investment alternatives.CHAPTER 031. Assume you purchased 200 shares of XYZ common stock on margin at $70 pershare from your broker. If the initial margin is 55%, how much did you borrow from the broker?A) $6,000B) $4,000C) $7,700D) $7,000E) $6,300Answer: E Difficulty: ModerateRationale: 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 marginis 60%. Your initial investment wasA) $4,800.B) $12,000.C) $5,600.D) $7,200.E) none of the above.Answer: D Difficulty: ModerateRationale: 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%. Below what stock price level would you get a margin call? Assume the stock pays no dividend; ignore interest on margin.A) $21B) $50C) $49D) $80E) none of the aboveAnswer: B Difficulty: DifficultRationale: 100 shares * $70 * .5 = $7,000 * 0.5 = $3,500 (loan amount); 0.30 = (100P - $3,500)/100P; 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) 0.33B) 0.55C) 0.43D) 0.23E) 0.25Answer: E Difficulty: DifficultRationale: 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. Theinitial margin is 60% and the stock pays no dividend. What would your rate of return be if you sell the stock at $45 per share? Ignore interest on margin.A) 25%B) -33%C) 44%D) -42%E) –54%Answer: D Difficulty: DifficultRationale: 300($60)(0.60) = $10,800 investment; 300($60) = $18,000 *(0.40) = $7,200 loan; Proceeds after selling 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 initialmargin at 50%. What would be your rate of return if you repurchase the stock at $40/share? The stock paid no dividends during the period, and you did not remove any money from the account before making the offsetting transaction.A) 20%B) 25%C) 22%D) 77%E) none of the aboveAnswer: C Difficulty: ModerateRationale: Profit on stock = ($45 - $40) * 100 = $500, $500/$2,250 (initial investment) =22.22%7. You want to purchase XYZ stock at $60 from your broker using as little of yourown money as possible. If initial margin is 50% and you have $3000 to invest, how many shares can you buy?A) 100 sharesB) 200 sharesC) 50 sharesD) 500 sharesE) 25 sharesAnswer: A Difficulty: ModerateRationale: .5 = [(Q * $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 of50%. The next day Qualitycorp's price drops to $25 per share. What is your actual margin?A) 50%B) 40%C) 33%D) 60%E) 25%Answer: B Difficulty: ModerateRationale: AM = [300 ($25) - .5 (300) ($30) ] / [300 ($25)] = .409. You sold short 100 shares of common stock at $45 per share. The initial marginis 50%. Your initial investment wasA) $4,800.B) $12,000.C) $2,250.D) $7,200.E) none of the above.Answer: C Difficulty: ModerateRationale: 100 shares * $45/share * 0.50 = $4,500 * 0.50 = $2,25010.
