C) unique risk, nondiversifiable risk.

D) unique risk, diversifiable risk.

E) none of the above.

Answer: B Difficulty: Easy

Rationale: Market, systematic, and nondiversifiable risk are synonyms referring to the risk that cannot be eliminated from the portfolio. Diversifiable, unique, nonsystematic, and firm-specific risks are synonyms referring to the risk that can be eliminated from the portfolio by diversification.

2. The risk that can be diversified away is

A) firm specific risk.

B) beta.

C) systematic risk.

D) market risk.

E) none of the above.

Answer: A Difficulty: Easy

A) securities' returns are uncorrelated.

B) securities' returns are positively correlated.

C) securities' returns are high.

D) securities' returns are negatively correlated.

E) B and C.

Answer: D Difficulty: Moderate

Rationale: Negative correlation among securities results in the greatest reduction of portfolio risk, which is the goal of diversification.

6. The efficient frontier of risky assets is

A) the portion of the investment opportunity set that lies above the global minimum

variance portfolio.

B) the portion of the investment opportunity set that represents the highest standard

deviations.

C) the portion of the investment opportunity set which includes the portfolios with the

lowest standard deviation.

D) the set of portfolios that have zero standard deviation.

E) both A and B are true.

Answer: A Difficulty: Moderate

Rationale: Portfolios on the efficient frontier are those providing the greatest expected return for a given amount of risk. Only those portfolios above the global minimum variance portfolio meet this criterion.

of the risky securities.

B) the line that connects the risk-free rate and the portfolio of the risky securities that

has the highest expected return on the efficient frontier.

C) the line tangent to the efficient frontier of risky securities drawn from the risk-free

rate.

D) the horizontal line drawn from the risk-free rate.

E) none of the above.

Answer: C Difficulty: Moderate

Rationale: The Capital Allocation Line represents the most efficient combinations of the risk-free asset and risky securities. Only C meets that definition.

8. Consider an investment opportunity set formed with two securities that are perfectly

negatively correlated. The global minimum variance portfolio has a standard deviation that is always

A) greater than zero.

B) equal to zero.

C) equal to the sum of the securities' standard deviations.

D) equal to -1.

E) none of the above.

Answer: B Difficulty: Difficult

Rationale: If two securities were perfectly negatively correlated, the weights for the minimum variance portfolio for those securities could be calculated, and the standard deviation of the resulting portfolio would be zero.

9. Which of the following statements is (are) true regarding the variance of a portfolio of

two risky securities?

A) The higher the coefficient of correlation between securities, the greater the

reduction in the portfolio variance.

B) There is a linear relationship between the securities' coefficient of correlation and

the portfolio variance.

C) The degree to which the portfolio variance is reduced depends on the degree of

correlation between securities.

D) A and B.

E) A and C.

Answer: C Difficulty: Moderate

Rationale: The lower the correlation between the returns of the securities, the more portfolio risk is reduced.

standard deviations.

B) have the highest rates of return for a given level of risk.

C) are selected from those securities with the lowest standard deviations regardless of

their returns.

D) have the highest risk and rates of return and the highest standard deviations.

E) have the lowest standard deviations and the lowest rates of return.

Answer: B Difficulty: Moderate

Rationale: Portfolios that are efficient are those that provide the highest expected return for a given level of risk.

11. Which of the following statement(s) is (are) true regarding the selection of a portfolio

from those that lie on the Capital Allocation Line?

A) Less risk-averse investors will invest more in the risk-free security and less in the

optimal risky portfolio than more risk-averse investors.

B) More risk-averse investors will invest less in the optimal risky portfolio and more in

the risk-free security than less risk-averse investors.

C) Investors choose the portfolio that maximizes their expected utility.

D) A and C.

E) B and C.

Answer: E Difficulty: Moderate

Rationale: All rational investors select the portfolio that maximizes their expected

utility; for investors who are relatively more risk-averse, doing so means investing less in the optimal risky portfolio and more in the risk-free asset.

0.2(12% - 13.2%)(6% - 7.7%) + 0.3(14% - 13.2%)(9% - 7.7%) + 0.2(15% - 13.2%)(8%

- 7.7%) = 0.76; rA,B = 0.76/[(1.1)(1.5)] = 0.47.

15. If you invest 40% of your money in A and 60% in B, what would be your portfolio's

expected rate of return and standard deviation?

A) 9.9%; 3%

B) 9.9%; 1.1%

C) 11%; 1.1%

D) 11%; 3%

E) none of the above

20. The risk-free portfolio that can be formed with the two securities will earn _____ rate of

return.

A) 8.5%

B) 9.0%

C) 8.9%

D) 9.9%

E) none of the above

Answer: C Difficulty: Difficult

Rationale: E(R P) = 0.43(10%) + 0.57(8%) = 8.86%.

21. Which of the following portfolio(s) is (are) most efficient?

A) 45 percent in A and 55 percent in B.

B) 65 percent in A and 35 percent in B.

C) 35 percent in A and 65 percent in B.

D) A and B are both efficient.

E) A and C are both efficient.

Answer: D Difficulty: Difficult

Rationale: The Portfolio E(Rp), sp, and Reward/volatility ratios are 45A/55B: 8.9%,

0.6%, 14.83; 65A/35B: 9.3%, 6.2%, 1.5; 35A/65B: 8.7%, 2.2%, 3.95. Both A and B are

efficient according to the mean-variance criterion. A has a much higher

Reward/volatility ratio.

22. An investor who wishes to form a portfolio that lies to the right of the optimal risky

portfolio on the Capital Allocation Line must:

A) lend some of her money at the risk-free rate and invest the remainder in the optimal

risky portfolio.

B) borrow some money at the risk-free rate and invest in the optimal risky portfolio.

C) invest only in risky securities.

D) such a portfolio cannot be formed.

E) B and C

Answer: E Difficulty: Moderate

Rationale: The only way that an investor can create portfolios to the right of the Capital Allocation Line is to create a borrowing portfolio (buy stocks on margin). In this case, the investor will not hold any of the risk-free security, but will hold only risky securities.

23. Which one of the following portfolios cannot lie on the efficient frontier as described

by Markowitz?

A) Only portfolio W cannot lie on the efficient frontier.

B) Only portfolio X cannot lie on the efficient frontier.

C) Only portfolio Y cannot lie on the efficient frontier.

D) Only portfolio Z cannot lie on the efficient frontier.

E) Cannot tell from the information given.

Answer: A Difficulty: Moderate

Rationale: When plotting the above portfolios, only W lies below the efficient frontier as described by Markowitz. It has a higher standard deviation than Z with a lower expected return.

24. Which one of the following portfolios cannot lie on the efficient frontier as described

by Markowitz?

A) Only portfolio A cannot lie on the efficient frontier.

B) Only portfolio B cannot lie on the efficient frontier.

C) Only portfolio C cannot lie on the efficient frontier.

D) Only portfolio D cannot lie on the efficient frontier.

E) Cannot tell from the information given.

Answer: D Difficulty: Moderate

Rationale: When plotting the above portfolios, only W lies below the efficient frontier as described by Markowitz. It has a higher standard deviation than Z with a lower expected return.

25. Portfolio theory as described by Markowitz is most concerned with:

A) the elimination of systematic risk.

B) the effect of diversification on portfolio risk.

C) the identification of unsystematic risk.

D) active portfolio management to enhance returns.

E) none of the above.

Answer: B Difficulty: Moderate

Rationale: Markowitz was concerned with reducing portfolio risk by combining risky securities with differing return patterns.

26. The measure of risk in a Markowitz efficient frontier is:

A) specific risk.

B) standard deviation of returns.

C) reinvestment risk.

D) beta.

E) none of the above.

Answer: B Difficulty: Moderate

Rationale: Markowitz was interested in eliminating diversifiable risk (and thus

lessening total risk) and thus was interested in decreasing the standard deviation of the returns of the portfolio.

27. A statistic that measures how the returns of two risky assets move together is:

A) variance.

B) standard deviation.

C) covariance.

D) correlation.

E) C and D.

Answer: E Difficulty: Moderate

Rationale: Covariance measures whether security returns move together or in

opposition; however, only the sign, not the magnitude, of covariance may be interpreted.

Correlation, which is covariance standardized by the product of the standard deviations of the two securities, may assume values only between +1 and -1; thus, both the sign and the magnitude may be interpreted regarding the movement of one security's return

relative to that of another security.

28. The unsystematic risk of a specific security

A) is likely to be higher in an increasing market.

B) results from factors unique to the firm.

C) depends on market volatility.

D) cannot be diversified away.

E) none of the above.

Answer: B Difficulty: Moderate

Rationale: Unsystematic (or diversifiable or firm-specific) risk refers to factors unique to the firm. Such risk may be diversified away; however, market risk will remain.

29. Which statement about portfolio diversification is correct?

A) Proper diversification can reduce or eliminate systematic risk.

B) The risk-reducing benefits of diversification do not occur meaningfully until at least

50-60 individual securities have been purchased.

C) Because diversification reduces a portfolio's total risk, it necessarily reduces the

portfolio's expected return.

D) Typically, as more securities are added to a portfolio, total risk would be expected

to decrease at a decreasing rate.

E) None of the above statements is correct.

Answer: D Difficulty: Moderate

Rationale: Diversification can eliminate only nonsystematic risk; relatively few

securities are required to reduce this risk, thus diminishing returns result quickly.

Diversification does not necessarily reduce returns.

30. The individual investor's optimal portfolio is designated by:

A) The point of tangency with the indifference curve and the capital allocation line.

B) The point of highest reward to variability ratio in the opportunity set.

C) The point of tangency with the opportunity set and the capital allocation line.

D) The point of the highest reward to variability ratio in the indifference curve.

E) None of the above.

Answer: A Difficulty: Moderate

Rationale: The indifference curve represents what is acceptable to the investor; the capital allocation line represents what is available in the market. The point of tangency represents where the investor can obtain the greatest utility from what is available.

31. For a two-stock portfolio, what would be the preferred correlation coefficient between

the two stocks?

A) +1.00.

B) +0.50.

C) 0.00.

D) -1.00.

E) none of the above.

Answer: D Difficulty: Moderate

Rationale: The correlation coefficient of -1.00 provides the greatest diversification

benefits.

32. In a two-security minimum variance portfolio where the correlation between securities

is greater than -1.0

A) the security with the higher standard deviation will be weighted more heavily.

B) the security with the higher standard deviation will be weighted less heavily.

C) the two securities will be equally weighted.

D) the risk will be zero.

E) the return will be zero.

Answer: B Difficulty: Difficult

Rationale: The security with the higher standard deviation will be weighted less heavily to produce minimum variance. The return will not be zero; the risk will not be zero unless the correlation coefficient is -1.

33. Which of the following is not a source of systematic risk?

A) the business cycle.

B) interest rates.

C) personnel changes

D) the inflation rate.

E) exchange rates.

Answer: C Difficulty: Easy

Rationale: Personnel changes are a firm-specific event that is a component of

non-systematic risk. The others are all sources of systematic risk.

34. The global minimum variance portfolio formed from two risky securities will be

riskless when the correlation coefficient between the two securities is

A) 0.0

B) 1.0

C) 0.5

D) -1.0

E) negative

Answer: D Difficulty: Moderate

Rationale: The global minimum variance portfolio will have a standard deviation of zero whenever the two securities are perfectly negatively correlated.

35. Security X has expected return of 12% and standard deviation of 20%. Security Y has

expected return of 15% and standard deviation of 27%. If the two securities have a correlation coefficient of 0.7, what is their covariance?

A) 0.038

B) 0.070

C) 0.018

D) 0.013

E) 0.054

Answer: A Difficulty: Moderate

Rationale: Cov(r X, r Y) = (.7)(.20)(.27) = .0378

36. When two risky securities that are positively correlated but not perfectly correlated are

held in a portfolio,

A) the portfolio standard deviation will be greater than the weighted average of the

individual security standard deviations.

B) the portfolio standard deviation will be less than the weighted average of the

individual security standard deviations.

C) the portfolio standard deviation will be equal to the weighted average of the

individual security standard deviations.

D) the portfolio standard deviation will always be equal to the securities' covariance.

E) none of the above is true.

Answer: B Difficulty: Moderate

Rationale: Whenever two securities are less than perfectly positively correlated, the standard deviation of the portfolio of the two assets will be less than the weighted

average of the two securities' standard deviations. There is some benefit to

diversification in this case.

37. The line representing all combinations of portfolio expected returns and standard

deviations that can be constructed from two available assets is called the

A) risk/reward tradeoff line

B) Capital Allocation Line

C) efficient frontier

D) portfolio opportunity set

E) Security Market Line

Answer: D Difficulty: Easy

Rationale: The portfolio opportunity set is the line describing all combinations of

expected returns and standard deviations that can be achieved by a portfolio of risky assets.

38. Given an optimal risky portfolio with expected return of 14% and standard deviation of

22% and a risk free rate of 6%, what is the slope of the best feasible CAL?

A) 0.64

B) 0.14

C) 0.08

D) 0.33

E) 0.36

Answer: E Difficulty: Moderate

Rationale: Slope = (14-6)/22 = .3636

39. The risk that can be diversified away in a portfolio is referred to as ___________.

I)diversifiable risk

II)unique risk

III)systematic risk

IV)firm-specific risk

A) I, III, and IV

B) II, III, and IV

C) III and IV

D) I, II, and IV

E) I, II, III, and IV

Answer: D Difficulty: Moderate

Rationale: All of these terms are used interchangeably to refer to the risk that can be removed from a portfolio through diversification.

40. As the number of securities in a portfolio is increased, what happens to the average

portfolio standard deviation?

A) It increases at an increasing rate.

B) It increases at a decreasing rate.

C) It decreases at an increasing rate.

D) It decreases at a decreasing rate.

E) It first decreases, then starts to increase as more securities are added.

Answer: D Difficulty: Moderate

Rationale: Statman's study showed that the risk of the portfolio would decrease as

random stocks were added. At first the risk decreases quickly, but then the rate of

decrease slows substantially, as shown in Figure 7.2. The minimum portfolio risk in the study was 19.2%.

41. In words, the covariance considers the probability of each scenario happening and the

interaction between

A) securities' returns relative to their variances.

B) securities' returns relative to their mean returns.

C) securities' returns relative to other securities' returns.

D) the level of return a security has in that scenario and the overall portfolio return.

E) the variance of the security's return in that scenario and the overall portfolio

variance.

Answer: B Difficulty: Difficult

Rationale: As written in equation 7.4, the covariance of the returns between two

securities is the sum over all scenarios of the product of three things. The first item is the probability that the scenario will happen. The second and third terms represent the deviations of the securities' returns in that scenario from their own expected returns. 42. The standard deviation of a two-asset portfolio is a linear function of the assets' weights

when

A) the assets have a correlation coefficient less than zero.

B) the assets have a correlation coefficient equal to zero.

C) the assets have a correlation coefficient greater than zero.

D) the assets have a correlation coefficient equal to one.

E) the assets have a correlation coefficient less than one.

Answer: D Difficulty: Moderate

Rationale: When there is a perfect positive correlation (or a perfect negative correlation), the equation for the portfolio variance simplifies to a perfect square. The result is that the portfolio's standard deviation is linear relative to the assets' weights in the portfolio.

43. A two-asset portfolio with a standard deviation of zero can be formed when

A) the assets have a correlation coefficient less than zero.

B) the assets have a correlation coefficient equal to zero.

C) the assets have a correlation coefficient greater than zero.

D) the assets have a correlation coefficient equal to one.

E) the assets have a correlation coefficient equal to negative one.

Answer: E Difficulty: Moderate

Rationale: When there is a perfect negative correlation, the equation for the portfolio variance simplifies to a perfect square. The result is that the portfolio’s standard

deviation equals |w AσA– w BσB|, which can be set equal to zero. The solution w A = σB/(σA+ σB) and w B = 1 – w A will yield a zero-standard deviation portfolio.

44. When borrowing and lending at a risk-free rate are allowed, which Capital Allocation

Line (CAL) should the investor choose to combine with the efficient frontier?

I)with the highest reward-to-variability ratio.

II)that will maximize his utility.

III)with the steepest slope.

IV)with the lowest slope.

A) I and III

B) I and IV

C) II and IV

D) I only

E) I, II, and III

Answer: E Difficulty: Difficult

Rationale: The optimal CAL is the one that is tangent to the efficient frontier. This CAL offers the highest reward-to-variability ratio, which is the slope of the CAL. It will also allow the investor to reach his highest feasible level of utility.

45. Which Excel tool can be used to find the points along an efficient frontier?

A) Regression

B) Solver

C) Scenarios

D) Goal Seek

E) Data Analysis

Answer: B Difficulty: Moderate

Rationale: Even if the student isn't familiar with Excel's Solver tool, he should

recognize it from the discussion in the text.

46. The separation property refers to the conclusion that

A) the determination of the best risky portfolio is objective and the choice of the best

complete portfolio is subjective.

B) the choice of the best complete portfolio is objective and the determination of the

best risky portfolio is objective.

C) the choice of inputs to be used to determine the efficient frontier is objective and the

choice of the best CAL is subjective.

D) the determination of the best CAL is objective and the choice of the inputs to be

used to determine the efficient frontier is subjective.

E) investors are separate beings and will therefore have different preferences regarding

the risk-return tradeoff.

Answer: A Difficulty: Difficult

Rationale: The determination of the optimal risky portfolio is purely technical and can be done by a manager. The complete portfolio, which consists of the optimal risky

portfolio and the risk-free asset, must be chosen by each investor based on preferences. Use the following to answer questions 47-50:

Consider the following probability distribution for stocks A and B:

47. The expected rates of return of stocks A and B are _____ and _____, respectively.

A) 13.2%; 9%.

B) 13%; 8.4%

C) 13.2%; 7.7%

D) 7.7%; 13.2%

国际投资学教程课后题答案 完整版

第一章 1.名词解释: 国际投资:是指以资本增值和生产力提高为目标的国际资本流动,是投资者将其资本投入国外进行的一阴历为目的的经济活动。 国际公共(官方)投资: 是指一国政府或国际经济组织为了社会公共利益而进行的投资,一般带有国际援助的性质。 国际私人投资:是指私人或私人企业以营利为目的而进行的投资。 短期投资:按国际收支统计分类,一年以内的债权被称为短期投资。 长期投资:一年以上的债权、股票以及实物资产被称为长期投资。 产业安全:可以分为宏观和中观两个层次。宏观层次的产业安全,是指一国制度安排能够导致较合理的市场结构及市场行为,经济保持活力,在开放竞争中本国重要产业具有竞争力,多数产业能够沈村冰持续发展。中观层次上的产业安全,是指本国国民所控制的企业达到生存规模,具有持续发展的能力及较大的产业影响力,在开放竞争中具有一定优势。 资本形成规模:是指一个经济落后的国家或地区如何筹集足够的、实现经济起飞和现代化的初始资本。 2、简述20世纪70年代以来国际投资的发展出现了哪些新特点 (一)投资规模,国际投资这这一阶段蓬勃发展,成为世纪经济舞台最为活跃的角色。国际直接投资成为了国际经济联系中更主要的载体。 (二)投资格局,1.“大三角”国家对外投资集聚化 2.发达国家之间的相互投资不断增加 3.发展中国家在吸引外资的同时,也走上了对外投资的舞台 (三)投资方式,国际投资的发展出现了直接投资与间接投资齐头并进的发展局面。 (四)投资行业,第二次世界大战后,国际直接投资的行业重点进一步转向第二产业。 3.如何看待麦克杜格尔模型的基本理念 麦克杜格尔模型是麦克杜格尔在1960年提出来,后经肯普发展,用于分析国际资本流动的一般理论模型,其分析的是国际资本流动对资本输出国、资本输入国及整个世界生产和国民收入分配的影响。麦克杜格尔和肯普认为,国际间不存在限制资本流动的因素,资本可以自由地从资本要素丰富的国家流向资本要素短缺的国家。资本流动的原因在于前者的资本价格低于后者。资本国际流动的结果将通过资本存量的调整使各国资本价格趋于均等,从而提高世界资源的利用率,增加世界各国的总产量和各国的福利。 虽然麦克杜格尔模型的假设较之现实生活要简单得多,且与显示生活有很大的反差,但是这个模型的理念确实是值得称道的,既国际投资能够同时增加资本输出输入国的收益,从而增加全世界的经济收益。 第二章 三优势范式 决定跨国公司行为和对外直接投资的最基本因素有三,即所有权优势、内部化优势和区位优势。 所有权特定优势(Ownership)指一国企业拥有能够得到别国企业没有或难以得到的资本、规模、技术、管理和营销技能等方面的优势。邓宁认为的所有权特定优势有以下几个方面:①资产性所有权优势。对有价值资产的拥有大公司常常以较低的利率获得贷

博迪投资学第九版英文答案

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 efficiently. 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 these 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 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 housing 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 assets 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 financing more difficult, thereby increasing the cost of capital. A higher cost of capital results in less investment and lower real growth.

①采用资本资产定价模型计算A 股票的必要收益率。 ②计算B 股票价值,为拟投资该股票的投资者做出是否投资的决策,并说明理由。假定B 股票当前每股市价为15元,最近一期发放的每股股利为2.2元,预计年股利增长率为4%。 ③计算A 、B 、C 投资组合的β系数和必要收益率。假定投资者购买A 、B 、C 三种股票的比例为1:3:6。 ④已知按3:5:2的比例购买A 、B 、D 三种股票,所形成的A 、B 、D 投资组合的β系数为0.96,该组合的必要收益率为14.6%;如果不考虑风险大小,请在A 、B 、C 和A 、B 、D 两种投资组合中做出投资决策,并说明理由。 ①A 股票必要收益率=5%+0.91×(15%-5%)=14.1% ②B 股票价值=2.2×(1+4%)/(16.7%-4%)=18.02(元) 因为股票的价值18.02高于股票的市价15,所以可以投资B 股票。 ③投资组合中A 股票的投资比例=1/(1+3+6)=10% 投资组合中B 股票的投资比例=3/(1+3+6)=30% 投资组合中C 股票的投资比例=6/(1+3+6)=60% 投资组合的β系数= 0.91×10%+1.17×30%+1.8×60%=1.52 投资组合的必要收益率=5%+1.52×(15%-5%)=20.2% ④本题中资本资产定价模型成立,所以预期收益率等于按照资本资产定价模型计算的必要收益率,即A 、B 、C 投资组合的预期收益率大于A 、B 、D 投资组合的预期收益率,所以如果不考虑风险大小,应选择A 、B 、C 投资组合。 4、某公司2000年按面值购进国库券50万元,票面年利率为8%,三年期。购进后一年,市场利率上升到9%,则该公司购进该债券一年后的损失是多少? 国库券到期值=50×(1+3×8%)=62(万元) 一年后的本利和=50×(1+8%)=54(万元) 损失=54-52.18=1.82(万元) 5.假设某投资者选择了A 、B 两个公司的股票构造其证券投资组合,两者各占投资总额的一半。已知A 股票的期望收益率为24%,方差为16%,B 股票的期望收益为12%,方差为9%。请计算当A 、B 两只股票的相关系数各为:(1)1=AB ρ;

2020年投资学试题及答案(精选干货)

投资学复习要点 投资学的考试,都要尽可能给出图表、公式,比如简答题和论述题,如果你仅仅是文字描述,最多得一半的分,这个答题的规则和惯例要切记。 一、概念题 1.风险与收益的最优匹配 即是在一定风险下追求更高的收益;或是在一定收益下追求更低的风险。对风险与收益的量化以及对投资者风险偏好的分类,是构建资产组合时首先要解决的一个基础问题。2.优先股特点 1、优先股通常预先定明股息收益率。 2、优先股的权利范围小。 3、如果公司股东大会需要讨论与优先股有关的索偿权,即优先股的索偿权先于普通股,而次于债权人。3.资本市场的无差异曲线 对于一个特定风险厌恶的投资者而言,任意给定一个资产组合,根据他对风险的态度,按照期望收益率对风险补偿的要求,就可以得到一系列满意程度相同(无差异)的证券组合。

4.资本市场的无差异曲线 5.风险溢价 风险溢价是指超过无风险资产收益的预期收益,这一溢价为投资的风险提供了补偿。其中的无风险资产,是指其收益确定,从而方差为零的资产.一般以货币市场基金或者短期国债作为无风险资产的代表品. 6.风险资产的可行集(Feasible Set ) 可行集又称为机会集,由它可以确定有效集。可行集代表一组证券所形成的所有组合,也就是说,所有可能的组合位于可行集的边界上或内部。一般而言,这一集合呈现伞形,具体形状依赖于所包含的特定证券,它可能更左或更右、更高或更低、更胖或更瘦。

7.资本配置线 对于任意一个由无风险资产和风险资产所构成的组合,其相应的预期收益率和标准差都落在连接无风险资产和风险资产的直线上.该线被称作资本配置线(capital allocation line,CAL)。E(rc)=rf+ [E (rp)-rf]......感谢聆听 二、简答题 1.风险厌恶型投资者效用曲线的特点 1,斜率为正.即为了保证效用相同,如果投资者承担的风险增加,则其所要求的收益率也会增加。对于不同的投资者其无差异曲线斜率越陡峭,表示其越厌恶风险:
