1. In the context of the Capital Asset Pricing Model (CAPM) the relevant measure of risk

is

A) unique risk.

B) beta.

C) standard deviation of returns.

D) variance of returns.

E) none of the above.

C) The CML is also called the security market line.

D) The CML always has a positive slope.

E) The risk measure for the CML is standard deviation.

Answer: C Difficulty: Moderate

Rationale: Both the Capital Market Line and the Security Market Line depict risk/return

relationships. However, the risk measure for the CML is standard deviation and the risk

measure for the SML is beta (thus C is not true; the other statements are true).

8. The market risk, beta, of a security is equal to

A) the covariance between the security's return and the market return divided by the

variance of the market's returns.

B) the covariance between the security and market returns divided by the standard

deviation of the market's returns.

C) the variance of the security's returns divided by the covariance between the security

and market returns.

D) the variance of the security's returns divided by the variance of the market's returns.

E) none of the above.

Answer: A Difficulty: Moderate

Rationale: Beta is a measure of how a security's return covaries with the market returns,

normalized by the market variance.

any security is equal to

A) Rf + β [E(RM)].

B) Rf + β [E(RM) - Rf].

C) β [E(RM)

- Rf].

D) E(RM) + Rf.

E) none of the above.

Answer: B Difficulty: Moderate

Rationale: A security with a positive alpha is one that is expected to yield an abnormal

positive rate of return, based on the perceived risk of the security, and thus is

underpriced.

15. According to the Capital Asset Pricing Model (CAPM), which one of the following

statements is false?

A) The expected rate of return on a security decreases in direct proportion to a decrease

in the risk-free rate.

B) The expected rate of return on a security increases as its beta increases.

A) is the most familiar expression of the CAPM to practitioners.

B) refers to the way in which the covariance between the returns on a stock and returns

on the market measures the contribution of the stock to the variance of the market

portfolio, which is beta.

C) assumes that investors hold well-diversified portfolios.

D) all of the above are true.

E) none of the above is true.

Answer: D Difficulty: Moderate

38. The security market line (SML)

A) can be portrayed graphically as the expected return-beta relationship.

B) can be portrayed graphically as the expected return-standard deviation of market

returns relationship.

C) provides a benchmark for evaluation of investment performance.

D) A and C.

E) B and C.

Answer: D Difficulty: Moderate

Rationale: The SML is a measure of expected return-beta (the CML is a measure of

expected return-standard deviation of market returns). The SML provides the expected

return-beta relationship for "fairly priced" securities; thus if a portfolio manager selects

securities that are underpriced and produces a portfolio with a positive alpha, this

portfolio manager would receive a positive evaluation.

39. Research by Jeremy Stein of MIT resolves the dispute over whether beta is a sufficient

pricing factor by suggesting that managers should use beta to estimate

Rationale: An underpriced security will have a higher expected return than the SML

would predict; therefore it will plot above the SML.

42. The risk premium on the market portfolio will be proportional to

A) the average degree of risk aversion of the investor population.

B) the risk of the market portfolio as measured by its variance.

C) the risk of the market portfolio as measured by its beta.

A) equal to the marginal price of risk for the market portfolio.

B) greater than the marginal price of risk for the market portfolio.

C) less than the marginal price of risk for the market portfolio.

D) adjusted by its degree of nonsystematic risk.

E) none of the above is true.

Answer: A Difficulty: Moderate

Rationale: In equilibrium, the marginal price of risk for a risky security must be equal to

the marginal price of risk for the market. If not, investors will buy or sell the security

until they are equal.

does this mean?

A) They plan for one identical holding period.

B) They are price-takers who can't affect market prices through their trades.

C) They are mean-variance optimizers.

D) They have the same economic view of the world.

Answer: C Difficulty: Moderate

Rationale: The mutual fund theorem is similar to the separation property. The technical

task of creating mutual funds can be delegated to professional managers; then

individuals combine the mutual funds with risk-free assets according to their

preferences. The passive strategy of investing in a market index fund is efficient.

51. The expected return -- beta relationship of the CAPM is graphically represented by

A) the security market line.

B) the capital market line.

C) the capital allocation line.

D) the efficient frontier with a risk-free asset.

Answer: B Difficulty: Moderate

Rationale: 15% < 5% + 2.1(11% - 5%) = 17.6%; therefore, stock is overpriced and

should be shorted.

Essay Questions

65. Discuss the differences between the capital market line and the security market line.

Difficulty: Moderate

Answer:

The capital market line measures the excess return (return of the portfolio over the

risk-free return) per unit of total risk, as measured by standard deviation. The CML

applies to efficient portfolios only. The security market line measures the excess returns

of a portfolio or a security per unit of systematic risk (beta). The SML applies to

individual securities and to all portfolios (whether efficiently diversified or not). Thus,

the SML has much general applications than the CML and is more broadly used. The

SML is frequently used to evaluate the performance of portfolio managers.

The rational of this question is to determine whether the students understand the basic

differences between these two common risk/return relationships resulting from the

capital asset pricing model.

66. Discuss the assumptions of the capital asset pricing model, and how these assumptions

relate to the "real world" investment decision process.

Difficulty: Difficult

Answer:

The assumptions are:

(a) The market is composed of many small investors, who are price-takers; i. e., perfect

competition. In reality this assumption was fairly realistic until recent years when

institutional investors increasingly began to influence the market with their large

transactions, especially those transactions via program trading. Since the 1987

market crash, circuit breakers on program trading have been enacted and market

volatility has decreased somewhat.

(b) All investors have the same holding period. Obviously, different investors have

different goals, and thus have different holding periods.

(c) Investments are limited to those that are publicly traded. In addition, it is assumed

that investors may borrow or lend any amount at a fixed, risk-free rate. Obviously,

investors may purchase assets that are not publicly traded; however, the dollar

volume of publicly traded assets is considerable. The assumption that investors can

borrow or lend any amount at a fixed, risk-free rate obviously is false. However, the

model can be modified to incorporate different borrowing and lending rates.

(d) Investors pay no taxes on returns and incur no transaction costs. Obviously,

investors do pay taxes and do incur transaction costs. The tax differentials across

different types of investment income and across different income levels have been

lessened as a result of the income tax simplification of 1986. Obviously, investors

should consider after-tax, not before-tax, returns; however, the no-tax assumption of

the model is not a serious departure from reality. In addition, any investment

vehicle should stand on its own merits, not its tax status (again, less of a problem

with the tax simplification of 1986). Compared to other investment alternatives,

such as real estate, transaction costs for securities are relatively low, unless the

investor is an active trader. The active trader should be sure that he or she is not

trading himself/herself out of a profit situation and into a loss situation and making

profits for the broker. In general, these assumptions are not serious violations of

"real world" scenarios.

(e) All investors are mean-variance efficient. This assumption implies that all investors

make decisions based on maximizing returns available at an acceptable risk level;

most investors probably make decisions in this manner. However, some investors

are pure wealth maximizers (regardless of the risk level); and other investors are so

risk averse that avoiding risk is their only goal.

(f) All investors have homogeneous expectations, meaning that given the same data all

investors would process the data in the same manner, resulting in the same

risk/return assessments for all investment alternatives. Obviously, we do not have

homogenous expectations; one only has to read the differing recommendations of

various analysts to realize that we have heterogeneous expectations. However,

modeling heterogeneous expectations would require multiple, specific models; the

homogenous expectations assumption allows the development of a generalized

model, the CAPM.

This question was designed to determine the student's understanding of the implications

of the assumptions of the CAPM and requires the student to integrate much of the

information introduced in the course to date and to integrate basic knowledge from

economics principles courses.

67. Discuss the mutual fund theorem.

Difficulty: Easy

Answer:

The mutual fund theorem is based on the concept that investors may obtain an efficient

portfolio by holding the market (investing in an S&P 500 index fund, for example). The

investor may adjust his or her holdings to the appropriate risk level by combining this

investment with investment in risk-free instruments. Thus, the investor is separating the

investment decision from the financing decision (separation theorem). Using this

approach the investor may have an efficient passive investment strategy.

This question tests the student's understanding of one of the fundamental results of the

CAPM.

68. Discuss how the CAPM might be used in capital budgeting decisions and utility rate

decisions.

Difficulty: Moderate

Answer:

The CAPM can be used to establish a hurdle rate for capital budgeting projects, based

on the projects' beta coefficients. For utility rate cases, the CAPM can be used to

determine the fair rate of return for the utilities' stockholders. Utility rates can then be

set to target these returns.

This question tests the student's awareness of the general nature of the CAPM and the

diversity of its applications.

69. List and discuss two of the assumptions of the CAPM.

Difficulty: Moderate

Answer:

Assumptions are 1) there are many investors, none of whom can have an impact on

market prices, 2) investors are single-period planners with myopic behavior, 3)

investments are limited to a universe of publicly traded financial assets and risk-free

borrowing and lending, 4) there are no taxes or transactions costs, 5) all investors are

rational mean-variance optimizers who use the Markowitz model for portfolio selection,

and 6) all investors share the same economic view of the world. Students may discuss

these items as presented in the chapter or expand the discussion.

The question gives the student some flexibility in choosing which assumptions to

discuss.
