投资学课后习题答案

第一章1. 答:交易机制指市场的交易规则和保证规则实施的技术以及规则和技术对定价机制的影响。
它的主要研究内容包括:从市场微观结构的角度去看,价格是在什么样的规则和程序中形成的,并分析交易机制对资产交易的过程和结果的影响。
2. 答:报价驱动机制与指令驱动机制的区别在于:①价格形成方式不同。
在采用做市商制度的市场上,证券的开盘价格和随后的交易价格是由做市商报出的,而指令驱动制度的开盘价与随后的交易价格都是竞价形成的。
前者从交易系统外部输入价格,后者的成交价格是在交易系统内部生成的。
②信息传递范围与速度不同。
采用做市商机制,投资者买卖指令首先报给做市商,做市商是唯一全面及时知晓买卖信息的交易商,成交量与成交价随后才会传递给整个市场。
在指令驱动机制中,买卖指令、成交量与成交价几乎同步传递给整个市场。
③交易量与价格维护机制不同。
在报价驱动机制中,做市商有义务维护交易量与交易价格。
而指令驱动机制则不存在交易量与交易价格的维护机制。
④处理大额买卖指令的能力不同。
做市商报价驱动机制能够有效处理大额买卖指令。
而在指令驱动机制中,大额买卖指令要等待交易对手的买卖盘,完成交易常常要等待较长时间。
其它交易机制还包括混合交易机制、特殊会员制度等。
3. 答:一般来说,做市商市场的流动性要高于竞价市场,即投资者在竞价市场所面临的执行风险要大于做市商市场。
但是,竞价市场的透明度要好于做市商市场,同时,做市商市场的平均交易成本要高于竞价市场。
竞价市场的优点:①透明度高。
在指令驱动制度中,买卖盘信息、成交量与成交价格信息等及时对整个市场发布,投资者几乎可以同步了解到交易信息。
透明度高,有利于投资者观察市场。
②信息传递速度快、范围广。
指令驱动制度几乎可以实现交易信息同步传递,整个市场可以同时分享交易信息,很难发生交易信息垄断。
③运行费用较低。
投资者买卖指令竞价成交,交易价格在系统内部生成,系统本身表现出自运行特征。
这种指令驱动系统,在处理大量小额交易指令方面,优越性较明显。

投资主体是投资权利体、投资责任体和投资利益体的内在统一。
一定的经济主体要成为真正的投资主体必须具有三个特征:(1)拥有投资权利,能相对独立地作出投资决策,包括投资目标的确定、投资方式的选择等方面的自主决策。
(2)投资主体必须承担相应的投资风险和责任,包括承担的政治风险、经济风险、法律风险和社会道德风险。
(3)投资主体必须享有一定的投资收益,不能享受投资收益的法人或自然人不是真正的投资主体。
2、答:计划经济和市场经济下投资决定的不同表现在四个方面:(1)计划经济下的投资决定。
计划经济下的投资制度是政府主导型的投资制度。
这种投资制度的典型是改革前的前苏联、东欧、和中国等国家。
①投资主体。
政府是主要、甚至是唯一的投资主体。
政府投资主体以中央政府为主,包揽了各行各业的几乎所有投资。
企业不是投资主体,只是政府部门的附属和政府投资的实施者。

投资学课后题及答案

投资学课后题及答案Chapter 1 The Investment Environment 1.What is a real asset?Real assets are used to produce goods and services. Real assets consist of land, labor, and buildings. These generate income to the economy and determine both the material wealth and productive capacity of the economy. Additionally, real assets appear on only one side of the balance sheet.2.What is a financial asset?Financial assets are claims on real assets and income from them. Financial assets consist of stocks and bonds. These contribute indirectly to the productive capacity of the economy. Additionally, financial assets appear on both sides of the balance sheet.3.What is consumption timing and why is it important? Consumption timing allows flexibility between earnings and spending. Therefore, when we are younger and we can consume more than we earn by borrowing money to by homes and automobiles. As we age, we can invest to so that we can retire someday and live off of our prior earnings. Financial assets4.What is allocation of risk and why is it important?Allocation of risk is creating assets with various degrees of risk. This enables firms to raise capital and also gives investors a choice of assets with various risk levels from which to choose5.What is separation of ownership and why is it important?The separation of ownership and management is important. Unlike a sole proprietorship where the owners are the managers, owners of corporations are stockholders. Stockholders elect the broad of directors that hires the management team. The objective that all owners can agree to is for management to maximize the value of the firm (share price).6.What are the three sectors of the economy and what is theirprimary need?A. Firms are typically net borrowers as they seek to expand the firm and require resources to take on valuable projects.B. Households are typically net savers as they seek to use consumption timing to plan for longer-term financial requirements such as educating their children and investing for retirement. As such, they are interested in risk and after tax returns of investments.C. Governments are typically net borrowers but their needs depend on the current relationship between tax receipts and expenditures7.List and explain four important functions that financialintermediates perform.Financial intermediaries connect borrowers and lenders. Financial intermediaries are able to sell their own securities and invest in the liabilities of other firms. As such they can:A. pool resources to spread management costs over an larger base which reduces costs to an individual investor.B. diversify investments by being able to invest in more securities.C. develop expertise through the increased volume of business that they do.D. achieve economies of scale by being spread research costs over the pool.]8.What is securitization and why is it important?Securitization allows borrowers to enter capital markets directly. Loans are arranged into pass-through securities (such as mortgage pool) and investors can invest in securities backed by those pools9.List and briefly explain five ways an investor can globallydiversityA primary market transaction is where securities are initially issued. Thus, the issuing firm receives the money and deliversthe securities. The secondary market is where existing securities are traded. Thus, the firm that originally issued the securities receives no proceeds from the transaction. The individual selling the securities receives the money and delivers the securities while the individual buying the securities delivers the money 10.The four types of markets where trading takes place are listedbelow.A. Direct search markets. In direct search markets buyers and sellers must find each other. These markets are characterized by sporadic trading and low-priced non-standard goods such as refrigerator or sofas.B. Brokered markets. In markets that have active trading, brokers find it profitable to offer search services to buyers and seller. One example of this is real estate.C. Dealer market. In dealer markets, the dealers specialize by buying and selling for their own account. Dealers profit from the difference between their buying price and selling price (bid-ask spread). The OTC market is a dealer market.D. Auction market. In an auction market, such as the NYSE, all tradersconverge in one place to buy or sell an asset. Auction markets require heavy trading to make them efficient.11.The five ways for investors to globally diversify portfolio arelisted and discussed below.A.Investors can purchase American Depository Receipts (ADR=s) whichare a certificate that is denominated in dollars and represents a claim ona bundle of stock.B.Investors can purchase directly purchase foreign securities offered forsale in dollars.C.Investors can purchase international mutual funds that invest ininternational securities.D.Investors can purchase derivatives on foreign securities.E.Investors can purchase World Equity Benchmark Shares (WEBS) whichuse the same structure as an ADR but allow an investor to tradeportfolios of foreign stocks in a selected country.Chapter 2 Financial Instruments1.The price quotations of Treasury bonds in the Wall Street Journalshow an ask price of 101:12 and a bid price of 101:07.A. As a buyer of the bond what is the dollar price you expect to pay?B. As a seller of the bond what is the dollar price you expect to receive?A. You would pay the ask price of the dealer, 10112/32 or 101.375% of$10,000, or $10,137.50.B. You would receive the bid price of the dealer, 1017/32 or 101.21875% of$10,000, or $10,121.875.2.An investor is considering the purchase of either a municipal or acorporate bond that pay before tax rates of return of 6.92% and9.67%, respectively. If the investor is in the 25% marginal taxbracket, his or her after tax rates of return on the municipal and corporate bonds would be_________ and _________, respectively.Corporate bonds are taxable, therefore the after tax return would ber c=0.0967(1-0.25) =0.0725 or 7.25%. Since municipal bonds are free of federal tax the after tax return is equal to the before tax rate of return r m=0.0692(1-0) =6.92%.3. A 6.25% 25-year municipal bond is currently priced to yield8.7%. For a taxpayer in the 25% marginal tax bracket, this bondwould offer an equivalent taxable yield of __________.The equivalent taxable yield is the yield divided by the quantity one minus the tax rate or r m/ (1-t). Therefore,0.087/0.75=11.6%.4.If three stocks comprise an index and the returns on the threestocks during a given period were 17%, -13%, and 6%, whatwould be the geometric return of the index?To compute a geometric average, add one to each of the returns and multiply each of the terms to find the geometric sum. To find the geometric average, the geometric sum is raised to 1/n and then one is subtracted. Therefore, the geometric mean is [(1.17) (0.87) (1.06)]1/3-1=2.566%.5.In order for you to be indifferent between the after tax returns ona corporate bond paying 8.15% and a tax-exempt municipalbond paying 6.32%, what would you tax bracket need to be? For you to be indifferent, the after tax returns would need to be equal. Since only the corporate bond is taxed, r c(1-t)= r m. Therefore,0.0632=0.0815(1-t), (1-t) =0.77546, and t=0.2245 or 22.45%.6. A $1,000 face value bond pays annual coupon payments of $65and is currently priced at $967. The current yield of the bond is __________.The current yield is annual interest divided by the current price ($65/$967) = 6.72%./doc/ec9d072a4b73f242336c5fe7.html pare the after tax return to a corporation that buys a share of preferred stock at the beginning of the year for $65, receives a dividend of $4.50 during the year, and sells the stock at the end of the year for $65. The corporation is in the 30% tax bracket.Answer the questions below based on the information given in the following table.Stock Price Number of shares outstandingStock A $35 2,000Stock B $82 4,500Stock C $21 1,600The total before tax income is the $4.50 dividend. Since the firm can exclude 70% of the dividend from tax, the firm must pay tax on 30% of the dividend, or ($4.50×0.30) =$1.35. Since the firm is in the 30% tax bracket the taxliability is $1.35×0.30=0.405. Therefore, the firm nets (after tax)$4.50-0.41=4.09. Since the firm experienced no capital gain (or loss), the after tax return is $4.09/$65 = 0.06292 or 6.29%.8.The price-weighted index constructed with the three stocks is__________.A price weighted index is constructed by adding the prices of the securities and dividing by the number of securities in the index ($35 + $82 + $21)/3 = $46.9.The value-weighted index constructed with the three stocksusing a divisor of 1,000 is __________.A value-weighted index is computed by first computing the market value of each stock (price time the number of shares outstanding). Once each market value is computed, add the market values together and divide by the divisor. In this case it is [($35×2,000) + ($82×4,500) +($21×1,600)]/1,000 = 472.60.10.Assume that the return on stocks A, B, and C (above) during theyear were 18%, -6%, and 30%, respectively.A.The return of the price-weighted index would be__________.B.The return of the value-weighted index would be__________.C.The arithmetic return of the equally weighted index wouldbe__________.A. To compute the return of the price-weighted index you need to find the new prices of the stocks and then compute the average as follows:Stock A = [$35×(1.18)] = $41.30Stock A = [$82×(0.94)] = $77.08Stock A = [$21×(1.30)] = $27.30Average = (41.30 + 77.08 +27.30)/3 = $48.56.The change in the index value (return) is (48.56 - 46)/46 = 5.565%.B. To compute the return of the value-weighted index you need to use the new prices to find the new value of the index. The return will be the change in the value of the index. In this case the new value is [($41.30×2,000) + ($77.08×4,500) + ($27.30×1,600)]/1,000 = 473.14. The old value is [($35×2,000) + ($82×4,500) + ($21×1,600)]/1,000 = 472.60. Therefore, the return is (473.14 – 472.60)/472.60 = 0.11%.C. The return of an equally weighted index is the sum of the return of eachsecurity in the index divided by the number of securities or [18% + (-6%) + 30%]/3 = 14%.Chapter 3 Security Markets1.Assume you purchased 400 shares of IBM common stock onmargin at $85 per share from your broker. If the initial margin is 60%, how much did you borrow from the broker?If you bought 400 shares@ $85/share, the cost is 400*$85=$34,000. Of this you invested $34,000*0.6=20,400 and borrowed $34,000*(1-0.6)=$13,600.2.You sold short 350 shares of common stock at $42 per share. Theinitial margin is 60%. Your initial investment was___________.If you sold short 350 share@ $42/share the proceeds are350*$42=$14,700. With a margin of 60% you must invest$14,700*0.6=$8,820.3.You purchased 1,000 shares of Cisco common stock on margin at$18 per share. Assume the initial margin is 50% and themaintenance margin is 30%. Below what stock price level would you get a margin call? Assume the stock pays no dividend; ignore interest on margin.If you purchased 1,000 shares@ $18/share the cost is$18*1,000=$18,000. Of this you must invest 50% and can borrow 50%.Therefore, the loan amount is $18,000*0.5=$9,000. Margin=[1,000P-$9,000]/1,000P.Therefore, 0.30 = (1,00P-$9,000)/1,000P; 300P=1,000P-$9,000;-700P=-$9,000; P=$12.864.You purchased 600 shares of common stock on margin at $27 pershare. Assume the initial margin is 50% and the stock pays nodividend. What would the maintenance margin be if a margin call is made at a stock price of $22? Ignore interest on margin. If you purchased 600 shares@ $27/share the cost is $27*600=$16,200.Therefore, you invest 50% and borrowed the other 50% of the amount.The loan amount is 16,200*0.5=%8,100.Margin = [600*$22-$8,100]/ 600*$22; Margin = 0.386 or 38.6%.5.You purchased 200 shares of common stock on margin at $35 pershare. Assume the initial margin is 50% and the stock pays no dividend. What would your rate of return be if you sell the stock at price of $45.50 per share? Ignore interest on margin.The initial investment is 200*$35*0.50=$3,500. The change in value of the stock is ($45.50-$35)*200 = $2,100. Therefore, the return =$2,000/$3,500 = 60%.6.Assume you sell short 100 shares of common stock at $30 pershare, with initial margin at 50% and the stock pays no dividend.What would your rate of return if you repurchase the stock at $37/share? The stock paid no dividends during the period, and you did not remove any money from the account before making the offsetting transaction.The profit on the stock is = ($30-$37)*100 = -$700. The initialinvestment is $100*0.30*0.5=1,500. Therefore, the return is-$700/$1,500 = -46.67%.7.You sold short 200 shares of common stock at $30 per share. Theinitial margin at 50%. At what stock price would you receive a margin call if the maintenance margin is 35%.The amount in your account is 200*$50*1.5 = $15,000 and you owe 200 shares of stock. Therefore your net equity is $15,000-200P.Margin = net equity/amount you owe or 0.35 = ($15,000 -200P)/200P.Rearranging, $70 = $15,000 – 200P; 270P=$15,000; P = $55.55.8.Assume you sold short 100 shares of common stock at $25 pershare. The initial margin at 50%. What would be themaintenance margin if a margin call is made at a stock price of $30?The amount your account is $25*100*1.5 = $3,750 and you owe 100 shares of stock. Therefore your net equity is $3,750-100P.Margin = net equity/amount you owe or 0.35 = ($3,750-100*$30)/100*$30=25%..Rearranging, $70 = $15,000 – 200P; 270P=$15,000; P = $55.55.9.You want to purchase AMAT stock at $42 from your broker usingas little of your own money as possible. If initial margin is 50% and you have $2,700 to invest, how many shares can you buy?The margin is 50% or = 0.5 = ($42Q - $2,700)/$42Q. Therefore, $21Q = $42Q - $2,700.Rearranging, -$21Q = -$2,700; Q = 128.54. Since you can only buy whole shares, you can buy 128 shares. Alternatively, you can buy[$2,700*2]/$42 = 128. 57 shares.10.You buy 150 shares of Citicorp for $25 per share and depositinitial margin of 50%. The next day Citicorp's price drop to $20 per share. What is your actual margin?The actual margin (AT) is AM = [150*$20-0.5*150*25]/[150*$20] =0.375 or 37.5%.Chapter 4 Mutual Funds and Other Investment Companies1. A mutual fund had NAV per share of $14.25 on January 1, 2003.On December 31 of the same year the fund's NAV was $14.87.Income distributions were $0.59 and the fund had capital gain distributions of $1.36. Without considering taxes and transactions costs, what rate of return did an investor receive on the fund last year?The return is calculated by finding the change in value of the investment divided by the price. The change in value is the capital gain (whether realized or not) plus the sum of all distributions. Therefore,Return= ($14.87 -14.25 + 0.59 + 1.36)/ $14.25 = 18.04%.2. A mutual fund had NAV per share of $16.25 on January 1, 2003.On December 31 of the same year the fund's rate of return was14.2%. Income distributions were $1.02 and the fund had capitalgain distributions of $0.63. Without considering taxes andtransactions costs, what ending NAV would you calculate?The return is equals the capital gain plus the all distributions divided by the investment. Therefore, 0.142 = (P - $16.25 + 1.02 + 0.63)/$16.25;P = $16.9075.3. A mutual fund had year-end assets of $316,000,000 andliabilities of $42,000,000. If the fund's NVA was $28.64, how many shares must have been held in the fund?The number of shares equals the assets minus the liabilities divided by the NAV. Therefore, ($316,000,000 -$42,000,000)/$28.64 =9,567,039.106 shares.4. A mutual fund had year-end assets of $750,000,000 andliabilities of $8,000,000. There were 40,750,000 shares in the fund at year end. What was the mutual fund's Net Asset Value? NAV equals assets minus liabilities divided by the number of shares.Therefore, ($750,000,000 – 8,000,000)/40,750,000 = $18.21.5. A mutual fund had average daily assets of $1.8 billion on 2003.The fund sold $625 million worth of stock and purchased $900 million worth of stock during the year. The fund's turnover ratio is ___________.Turnover is the value of securities sold divided by the average assets of the fund. Therefore, 625,000,000/1,800,000,000 = 34.7%.6.You purchased shares of a mutual fund at a price of $18 per shareat the beginning of the year and paid a front-end load of 5.75%.If the securities in which the fund invested increased in value by 12% during the year, and the fund's expense ratio was0.75%, your return of you sold the fund at the end of the year would be _______.Since the fund has a front-end load, only (1-load) (or 0.9425) times NAV(18) is actually invested and growing. The money invested will grow at12% minus the 0.75% fees (or 11.25%). Therefore, [($18)(0.9425)(1.12-0.075) - $18]/$18 = 4.85% return.7.Apex fund has a NAV of 16.12 and a front load of 5.62%. What isthe offer price?The offer price equals NAV divided by one minus load. Therefore, $16.12 / (1 – 0.0562) = $17.08.8.Exponential growth fund has an offer price of 14.77 and a load of6%. What is the NAV?The offer price times on minus load equals NAV. Therefore, NAV equals $14.77 (0.94) = $13.889. A fund owns only three stocks with prices and quantities shownbelow. The fund has 50,000 shares outstanding. If the fund has $47,000 in liabilities, its NAV is________.Stock Price Number of shares outstandingStock A $35 2,000Stock B $82 4,500Stock C $21 1,600The value of assets is [($35?2,000) + ($82?4,500) + ($21?1.600)] = $472,600. Since NAV is asset minus liabilities divided by the number of shares outstanding, NAV = ($472,600 - $47,000)/50,000 = $8.5110.You have decided to invest $10,000 in the Pinnacle fund. Overthe long haul, the Pinnacle fund is expected to earn a return of10.25% on the portfolio (gross of fees). However, Pinnacle fundoffers several classes of funds. Therefore, you can choose to paya front load of 5% and escape 12-b1 fees or you can avoid theload fee by paying 12-b1 fees of 0.75%. If you investmenthorizon is 16 years, which should you choose?Since both strategies have a claim on the same portfolio of securities, you need to compute you expected terminal wealth under each strategy.The terminal wealth in the no-load fund would be the initial investment ($10,000) times one plus the net rate of return (return minus 12-b1 fee) or 1.095 raised to the N number of years (16). Therefore, 10,00(1.095)16 = $42,719.48.The terminal wealth in the front-end load fund would be the initialinvestment in the portfolio ($10,000) (1-load) times on plus the rate of return or 1.1025 raised to the N number of years (16). Therefore,9,500(1.1025)16= $45,266.94.In this case, you would be better off with the load-end fund.———⼤猫。

第1章综合训练答案要点1.1单项选择题1.A2.D3.A4.B5.B1.2多项选择题1.ABCD2.ABCD3.AB4.BD5.AC1.3思考题1.本杰明·弗兰克说:钱生钱,并且所生之钱会生出更多的钱。
这就是货币时间价值的本质。
货币的时间价值这个概念认为,当前拥有的货币比未来收到的同样金额的货币具有更大的价值,因当前拥有的货币可以进行投资。
即使有通货膨胀的影响,只要存在投资机会,货币的现值就一定大于它的未来价值。
货币的时间价值就是指当前所持有的一定量货币比未来获得的等量货币具有更高的价值。
从经济学的角度而言,当前的一单位货币与未来的一单位货币的购买力之所以不同,是因为要节省现在的一单位货币不消费而改在未来消费,则在未来消费时必须有大于一单位的货币可供消费,作为弥补延迟消费的贴水。
从量的规定性来看,货币的时间价值是没有风险和没有通货膨胀下的社会平均资金利润率. 在计量货币时间价值时,风险报酬和通货膨胀因素不应该包括在内。
所以货币的时间价值是指货币经过一定时间的投资和再投资所增加的价值,称为资金的时间价值。
货币的时间价值不产生于生产与制造领域,产生于社会资金的流通领域。
货币时间价值来源依据:①节欲论。
投资者进行投资就必须推迟消费,对投资者推迟消费的耐心应给以报酬,这种报酬的量应与推迟的时货币的时间价值间成正比。
②劳动价值论。
资金运动的全过程:G—W…P…W’—G’G’=G+∆G包含增值额在内的全部价值是形成于生产过程的,其中增值部分是工人创造的剩余价值。
时间价值的真正来源是工人创造的剩余价值。
货币时间价值产生原因分析:(1)货币时间价值是资源稀缺性的体现。
经济和社会的发展要消耗社会资源,现有的社会资源构成现存社会财富,利用这些社会资源创造出来的将来物质和文化产品构成了将来的社会财富,由于社会资源具有稀缺性特征,又能够带来更多社会产品,所以当前物品的效用要高于未来物品的效用。
在货币经济条件下,货币是商品的价值体现,当前的货币用于支配当前的商品,将来的货币用于支配将来的商品,所以当前货币的价值自然高于未来货币的价值。

投资学课后题及答案Chapter 1 The Investment Environment 1.What is a real asset?Real assets are used to produce goods and services. Real assets consist of land, labor, and buildings. These generate income to the economy and determine both the material wealth and productive capacity of the economy. Additionally, real assets appear on only one side of the balance sheet.2.What is a financial asset?Financial assets are claims on real assets and income from them. Financial assets consist of stocks and bonds. These contribute indirectly to the productive capacity of the economy. Additionally, financial assets appear on both sides of the balance sheet.3.What is consumption timing and why is it important? Consumption timing allows flexibility between earnings and spending. Therefore, when we are younger and we can consume more than we earn by borrowing money to by homes and automobiles. As we age, we can invest to so that we can retire someday and live off of our prior earnings. Financial assets4.What is allocation of risk and why is it important?Allocation of risk is creating assets with various degrees of risk. This enables firms to raise capital and also gives investors a choice of assets with various risk levels from which to choose5.What is separation of ownership and why is it important?The separation of ownership and management is important. Unlike a sole proprietorship where the owners are the managers, owners of corporations are stockholders. Stockholders elect the broad of directors that hires the management team. The objective that all owners can agree to is for management tomaximize the value of the firm (share price).6.What are the three sectors of the economy and what is theirprimary need?A. Firms are typically net borrowers as they seek to expand the firm and require resources to take on valuable projects.B. Households are typically net savers as they seek to use consumption timing to plan for longer-term financial requirements such as educating their children and investing for retirement. As such, they are interested in risk and after tax returns of investments.C. Governments are typically net borrowers but their needs depend on the current relationship between tax receipts and expenditures7.List and explain four important functions that financialintermediates perform.Financial intermediaries connect borrowers and lenders. Financial intermediaries are able to sell their own securities and invest in the liabilities of other firms. As such they can:A. pool resources to spread management costs over an larger base which reduces costs to an individual investor.B. diversify investments by being able to invest in more securities.C. develop expertise through the increased volume of business that they do.D. achieve economies of scale by being spread research costs over the pool.]8.What is securitization and why is it important?Securitization allows borrowers to enter capital markets directly. Loans are arranged into pass-through securities (such as mortgage pool) and investors can invest in securities backed bythose pools9.List and briefly explain five ways an investor can globallydiversityA primary market transaction is where securities are initially issued. Thus, the issuing firm receives the money and delivers the securities. The secondary market is where existing securities are traded. Thus, the firm that originally issued the securities receives no proceeds from the transaction. The individual selling the securities receives the money and delivers the securities while the individual buying the securities delivers the money 10.The four types of markets where trading takes place are listed below.A. Direct search markets. In direct search markets buyers and sellers must find each other. These markets are characterized by sporadic trading and low-priced non-standard goods such as refrigerator or sofas.B. Brokered markets. In markets that have active trading, brokers find it profitable to offer search services to buyers and seller. One example of this is real estate.C. Dealer market. In dealer markets, the dealers specialize by buying and selling for their own account. Dealers profit from the difference between their buying price and selling price (bid-ask spread). The OTC market is a dealer market.D. Auction market. In an auction market, such as the NYSE, all tradersconverge in one place to buy or sell an asset. Auction markets require heavy trading to make them efficient.11.The five ways for investors to globally diversify portfolio arelisted and discussed below.A.Investors can purchase American Depository Receipts (ADR=s) whichare a certificate that is denominated in dollars and represents a claim ona bundle of stock.B.Investors can purchase directly purchase foreign securities offered forsale in dollars.C.Investors can purchase international mutual funds that invest ininternational securities.D.Investors can purchase derivatives on foreign securities.E.Investors can purchase World Equity Benchmark Shares (WEBS) whichuse the same structure as an ADR but allow an investor to tradeportfolios of foreign stocks in a selected country.Chapter 2 Financial Instruments1.The price quotations of Treasury bonds in the Wall Street Journalshow an ask price of 101:12 and a bid price of 101:07.A. As a buyer of the bond what is the dollar price you expect to pay?B. As a seller of the bond what is the dollar price you expect to receive?A. You would pay the ask price of the dealer, 10112/32 or 101.375% of$10,000, or $10,137.50.B. You would receive the bid price of the dealer, 1017/32 or 101.21875% of$10,000, or $10,121.875.2.An investor is considering the purchase of either a municipal or acorporate bond that pay before tax rates of return of 6.92% and9.67%, respectively. If the investor is in the 25% marginal taxbracket, his or her after tax rates of return on the municipal and corporate bonds would be_________ and _________, respectively.Corporate bonds are taxable, therefore the after tax return would ber c=0.0967(1-0.25) =0.0725 or 7.25%. Since municipal bonds are free of federal tax the after tax return is equal to the before tax rate of return r m=0.0692(1-0) =6.92%.3. A 6.25% 25-year municipal bond is currently priced to yield8.7%. For a taxpayer in the 25% marginal tax bracket, this bondwould offer an equivalent taxable yield of __________.The equivalent taxable yield is the yield divided by the quantity one minus the tax rate or r m/ (1-t). Therefore, 0.087/0.75=11.6%.4.If three stocks comprise an index and the returns on the threestocks during a given period were 17%, -13%, and 6%, what would be the geometric return of the index?To compute a geometric average, add one to each of the returns and multiply each of the terms to find the geometric sum. To find the geometric average, the geometric sum is raised to 1/n and then one is subtracted. Therefore, the geometric mean is [(1.17) (0.87) (1.06)]1/3-1=2.566%.5.In order for you to be indifferent between the after tax returns ona corporate bond paying 8.15% and a tax-exempt municipalbond paying 6.32%, what would you tax bracket need to be? For you to be indifferent, the after tax returns would need to be equal. Since only the corporate bond is taxed, r c(1-t)= r m. Therefore,0.0632=0.0815(1-t), (1-t) =0.77546, and t=0.2245 or 22.45%.6. A $1,000 face value bond pays annual coupon payments of $65and is currently priced at $967. The current yield of the bond is __________.The current yield is annual interest divided by the current price ($65/$967) = 6.72%./doc/e714998860.html,pare the after tax return to a corporation that buys a share ofpreferred stock at the beginning of the year for $65, receives a dividend of $4.50 during the year, and sells the stock at the end of the year for $65. The corporation is in the 30% tax bracket.Answer the questions below based on the information given in the following table.Stock Price Number of shares outstandingStock A $35 2,000Stock B $82 4,500Stock C $21 1,600The total before tax income is the $4.50 dividend. Since the firm can exclude 70% of the dividend from tax, the firm must pay tax on 30% of the dividend, or ($4.50×0.30) =$1.35. Since the firm is in the 30% tax bracket the taxliability is $1.35×0.30=0.405. Therefore, the firm nets (aftertax)$4.50-0.41=4.09. Since the firm experienced no capital gain (or loss), the after tax return is $4.09/$65 = 0.06292 or 6.29%.8.The price-weighted index constructed with the three stocks is__________.A price weighted index is constructed by adding the prices of the securities and dividing by the number of securities in the index ($35 + $82 + $21)/3 = $46.9.The value-weighted index constructed with the three stocksusing a divisor of 1,000 is __________.A value-weighted index is computed by first computing the market value of each stock (price time the number of shares outstanding). Once each market value is computed, add the market values together and divide by the divisor. In this case it is [($35×2,000) + ($82×4,500) +($21×1,600)]/1,000 = 472.60.10.Assume that the return on stocks A, B, and C (above) during theyear were 18%, -6%, and 30%, respectively.A.The return of the price-weighted index would be__________.B.The return of the value-weighted index would be__________.C.The arithmetic return of the equally weighted index wouldbe__________.A. To compute the return of the price-weighted index you need to find the new prices of the stocks and then compute the average as follows:Stock A = [$35×(1.18)] = $41.30Stock A = [$82×(0.94)] = $77.08Stock A = [$21×(1.30)] = $27.30Average = (41.30 + 77.08 +27.30)/3 = $48.56.The change in the index value (return) is (48.56 - 46)/46 =5.565%.B. To compute the return of the value-weighted index you need to use the new prices to find the new value of the index. The return will be the change in the value of the index. In this case the new value is [($41.30×2,000) + ($77.08×4,500) + ($27.30×1,600)]/1,000 = 473.14. The old value is [($35×2,000) + ($82×4,500) + ($21×1,600)]/1,000 = 472.60. Therefore, the return is (473.14 – 472.60)/472.60 = 0.11%.C. The return of an equally weighted index is the sum of the return of eachsecurity in the index divided by the number of securities or [18% + (-6%) + 30%]/3 = 14%.Chapter 3 Security Markets1.Assume you purchased 400 shares of IBM common stock onmargin at $85 per share from your broker. If the initial margin is 60%, how much did you borrow from the broker?If you bought 400 shares@ $85/share, the cost is 400*$85=$34,000. Of this you invested $34,000*0.6=20,400 and borrowed$34,000*(1-0.6)=$13,600.2.You sold short 350 shares of common stock at $42 per share. Theinitial margin is 60%. Your initial investment was___________.If you sold short 350 share@ $42/share the proceeds are350*$42=$14,700. With a margin of 60% you must invest$14,700*0.6=$8,820.3.You purchased 1,000 shares of Cisco common stock on margin at$18 per share. Assume the initial margin is 50% and themaintenance margin is 30%. Below what stock price level would you get a margin call? Assume the stock pays no dividend; ignore interest on margin.If you purchased 1,000 shares@ $18/share the cost is$18*1,000=$18,000. Of this you must invest 50% and can borrow 50%.Therefore, the loan amount is $18,000*0.5=$9,000. Margin= [1,000P-$9,000]/1,000P.Therefore, 0.30 = (1,00P-$9,000)/1,000P; 300P=1,000P-$9,000;-700P=-$9,000; P=$12.864.You purchased 600 shares of common stock on margin at $27 pershare. Assume the initial margin is 50% and the stock pays nodividend. What would the maintenance margin be if a margin call is made at a stock price of $22? Ignore interest on margin.If you purchased 600 shares@ $27/share the cost is $27*600=$16,200.Therefore, you invest 50% and borrowed the other 50% of the amount.The loan amount is 16,200*0.5=%8,100.Margin = [600*$22-$8,100]/ 600*$22; Margin = 0.386 or 38.6%.5.You purchased 200 shares of common stock on margin at $35 pershare. Assume the initial margin is 50% and the stock pays no dividend. What would your rate of return be if you sell thestock at price of $45.50 per share? Ignore interest on margin.The initial investment is 200*$35*0.50=$3,500. The change in value of the stock is ($45.50-$35)*200 = $2,100. Therefore, the return =$2,000/$3,500 = 60%.6.Assume you sell short 100 shares of common stock at $30 pershare, with initial margin at 50% and the stock pays no dividend.What would your rate of return if you repurchase the stock at $37/share? The stock paid no dividends during the period, and you did not remove any money from the account before making the offsetting transaction.The profit on the stock is = ($30-$37)*100 = -$700. The initial investment is $100*0.30*0.5=1,500. Therefore, the return is -$700/$1,500 = -46.67%.7.You sold short 200 shares of common stock at $30 per share. Theinitial margin at 50%. At what stock price would you receive a margin call if the maintenance margin is 35%.The amount in your account is 200*$50*1.5 = $15,000 and you owe 200 shares of stock. Therefore your net equity is $15,000-200P.Margin = net equity/amount you owe or 0.35 = ($15,000 -200P)/200P.Rearranging, $70 = $15,000 –200P; 270P=$15,000; P = $55.55.8.Assume you sold short 100 shares of common stock at $25 pershare. The initial margin at 50%. What would be themaintenance margin if a margin call is made at a stock price of $30?The amount your account is $25*100*1.5 = $3,750 and you owe 100 shares of stock. Therefore your net equity is $3,750-100P.Margin = net equity/amount you owe or 0.35 = ($3,750-100*$30)/100*$30=25%..Rearranging, $70 = $15,000 –200P; 270P=$15,000; P = $55.55.9.You want to purchase AMAT stock at $42 from your broker usingas little of your own money as possible. If initial margin is 50% and you have $2,700 to invest, how many shares can you buy?The margin is 50% or = 0.5 = ($42Q - $2,700)/$42Q. Therefore, $21Q = $42Q - $2,700.Rearranging, -$21Q = -$2,700; Q = 128.54. Since you can only buy whole shares, you can buy 128 shares. Alternatively, you can buy[$2,700*2]/$42 = 128. 57 shares.10.You buy 150 shares of Citicorp for $25 per share and depositinitial margin of 50%. The next day Citicorp's price drop to $20 per share. What is your actual margin?The actual margin (AT) is AM = [150*$20-0.5*150*25]/[150*$20] =0.375 or 37.5%.Chapter 4 Mutual Funds and Other Investment Companies1. A mutual fund had NAV per share of $14.25 on January 1, 2003.On December 31 of the same year the fund's NAV was $14.87.Income distributions were $0.59 and the fund had capitalgain distributions of $1.36. Without considering taxes and transactions costs, what rate of return did an investor receive on the fund last year?The return is calculated by finding the change in value of the investment divided by the price. The change in value is the capital gain (whether realized or not) plus the sum of all distributions. Therefore,Return= ($14.87 -14.25 + 0.59 + 1.36)/ $14.25 = 18.04%.2. A mutual fund had NAV per share of $16.25 on January 1, 2003.On December 31 of the same year the fund's rate of return was14.2%. Income distributions were $1.02 and the fund had capitalgain distributions of $0.63. Without considering taxes and transactions costs, what ending NAV would you calculate?The return is equals the capital gain plus the all distributions divided by the investment. Therefore, 0.142 = (P - $16.25 + 1.02 + 0.63)/$16.25;P = $16.9075.3. A mutual fund had year-end assets of $316,000,000 andliabilities of $42,000,000. If the fund's NVA was $28.64, how many shares must have been held in the fund?The number of shares equals the assets minus the liabilities divided by the NAV. Therefore, ($316,000,000 - $42,000,000)/$28.64 =9,567,039.106 shares.4. A mutual fund had year-end assets of $750,000,000 andliabilities of $8,000,000. There were 40,750,000 shares in thefund at year end. What was the mutual fund's Net Asset Value?NAV equals assets minus liabilities divided by the number of shares.Therefore, ($750,000,000 – 8,000,000)/40,750,000 = $18.21.5. A mutual fund had average daily assets of $1.8 billion on 2003.The fund sold $625 million worth of stock and purchased $900 million worth of stock during the year. The fund's turnover ratio is ___________.Turnover is the value of securities sold divided by the average assets of the fund. Therefore, 625,000,000/1,800,000,000 = 34.7%.6.You purchased shares of a mutual fund at a price of $18 per shareat the beginning of the year and paid a front-end load of 5.75%.If the securities in which the fund invested increased in value by 12% during the year, and the fund's expense ratio was 0.75%, your return of you sold the fund at the end of the year would be _______.Since the fund has a front-end load, only (1-load) (or 0.9425) times NAV(18) is actually invested and growing. The money invested will grow at12% minus the 0.75% fees (or 11.25%). Therefore, [($18)(0.9425)(1.12-0.075) - $18]/$18 = 4.85% return.7.Apex fund has a NAV of 16.12 and a front load of 5.62%. What isthe offer price?The offer price equals NAV divided by one minus load. Therefore, $16.12 / (1 – 0.0562) = $17.08.8.Exponential growth fund has an offer price of 14.77 and a load of6%. What is the NAV?The offer price times on minus load equals NAV. Therefore, NAV equals $14.77 (0.94) = $13.889. A fund owns only three stocks with prices and quantities shownbelow. The fund has 50,000 shares outstanding. If the fund has $47,000 in liabilities, its NAV is________.Stock Price Number of shares outstandingStock A $35 2,000Stock B $82 4,500Stock C $21 1,600The value of assets is [($35?2,000) + ($82?4,500) + ($21?1.600)] = $472,600. Since NAV is asset minus liabilities divided by the number of shares outstanding, NAV = ($472,600 - $47,000)/50,000 = $8.5110.You have decided to invest $10,000 in the Pinnacle fund. Overthe long haul, the Pinnacle fund is expected to earn a return of10.25% on the portfolio (gross of fees). However, Pinnacle fundoffers several classes of funds. Therefore, you can choose to paya front load of 5% and escape 12-b1 fees or you can avoid theload fee by paying 12-b1 fees of 0.75%. If you investmenthorizon is 16 years, which should you choose?Since both strategies have a claim on the same portfolio ofsecurities, you need to compute you expected terminal wealth under each strategy.The terminal wealth in the no-load fund would be the initial investment ($10,000) times one plus the net rate of return (return minus 12-b1 fee) or 1.095 raised to the N number of years (16). Therefore, 10,00(1.095)16 = $42,719.48.The terminal wealth in the front-end load fund would be the initialinvestment in the portfolio ($10,000) (1-load) times on plus the rate of return or 1.1025 raised to the N number of years (16). Therefore,9,500(1.1025)16= $45,266.94.In this case, you would be better off with the load-end fund.———大猫。
