Deck 15: A Basic Look at Portfolio Management and Capital Market Theory

Question 1

The idea behind the portfolio effect is that risk can be reduced by combining securities,but there will be a corresponding reduction in return.

Answer 1

True

Question 2

The steeper the slope on a risk-return indifference curve,the more anxious an investor is to take risks.

Answer 2

False

Question 3

The expected value is a commonly used measure of dispersion.

Answer 3

False

Question 4

According to the capital asset pricing model,it is possible to compose a portfolio with a return greater than any one on the efficient frontier,given equal risk,without borrowing funds for investment.

Question 5

The essence of the capital market line is that the only way to earn greater returns is to take increasingly greater risks.

Question 6

If a particular stock is less risky than the market,its beta coefficient will fall somewhere between -1 and 0.

Question 7

The standard deviation for a portfolio is a weighted average of the individual securities' standard deviations.

Question 8

Risk is generally associated only with loss from possible investments.

Question 9

The greater the negative correlation between two (or more)securities,the lower the portfolio standard deviation (all else being equal).

Question 10

Unsystematic risk earns a risk premium,because it cannot be offset through efficient portfolio management.

Question 11

An investor is indifferent between points on a risk-return indifference curve,though not indifferent to achieving the highest curve possible.

Question 12

Risk measurement usually considers only losses rather than the dispersion of all outcomes.

Question 13

The expected value for a portfolio is a weighted average of the individual securities' expected values.

Question 14

Unlike the capital market line,the security market line is unique for each investor.

Question 15

The capital market line enables investors to achieve a higher level of utility than they could on the efficient frontier.

Question 16

The point of tangency between the efficient frontier and the Security Market Line is considered to represent an optimum portfolio.

Question 17

Points below the efficient frontier have less desirable risk-return characteristics than those along the efficient frontier.

Question 18

Harry Markowitz developed the theory that an efficient set of portfolios exists which represent the maximum return possible for any given level of risk.

Question 19

Markowitz's theory asserts that the slope of indifference curves is determined by the investor's indifference to various portfolios.

Question 20

Points above the efficient frontier have superior risk-return characteristics to those along the efficient frontier,but are not part of the feasible set.

Question 21

In an efficient market context,the ability to achieve high returns may be more directly related to absorption of additional risk than superior ability in selecting stocks.

Question 22

Assume a portfolio has the possibility of returning 7%,8%,10%,or 12%,with a likelihood of 20%,30%,25%,and 25%,respectively.Considering the portfolio's standard deviation and expected value,would you say that this portfolio is of:

A)average yield,low-risk.
B)lower-than-average yield,low-risk.
C)average yield,average risk.
D)Not enough information to tell

Question 23

There is debate in regard to the capital asset pricing model about the appropriate R_F,K_M,and stability of beta.

Question 24

The security market line shows the risk-return trade-off for an individual security.

Question 25

By picking stocks that are not perfectly correlated,unsystematic risk may be eliminated.

Question 26

It can be assumed that the lower the expected value of an investment,the higher the standard deviation will be.

Question 27

An assumption of the capital asset pricing model is that investors can borrow or lend an unlimited amount of funds at a given risk-free rate.

Question 28

Points along the capital market line represent a combination of a risk-free asset and M (the market portfolio)with the possibility of borrowing beyond point M.

Question 29

The investor is only assumed to receive additional returns for unsystematic risk.

Question 30

In using the capital market line,the higher the portfolio standard deviation,the lower the anticipated return (K_p).

Question 31

The beta coefficient indicates how volatile a stock is,relative to the market.

Question 32

B)will only participate in low-risk or risk-free investments.
C)is one of a small minority in the United States.
D)More than one of the above

Question 34

In general,the greater the dispersion of outcomes,the lower the risk.

Question 35

A)5.717%.
B)3.510%.
C)1.873%.
D)6.480%.
E)3.842%.

Question 36

An underlying assumption to the CAPM model is that an individual can choose an investment combining the return on the risk-free asset with the market rate of return,and this will provide superior returns to the efficient frontier at all points except M,where they are equal.

Question 37

Systematic risk measures risk that is related to the market.

Question 38

The capital asset pricing model (CAPM)takes off where the efficient frontier concludes,with the introduction of a new investment outlet,the risk-free asset (R_F).
