Portfolio management I Flashcards
Evidence of risk aversion is best illustrated by a risk–return relationship that is ?
Positive
Explanation: Historical data over long periods of time indicate that there exists a positive risk–return relationship, which is a reflection of an investor’s risk aversion.
When considering a portfolio that is optimal for one investor, a second investor with a higher risk aversion would most likely:
A. expect a higher variance for the portfolio.
B. derive a lower utility from the portfolio.
C. have a lower return expectation for the portfolio.
B is Correct. Utility has two terms: the expected return and a negative term based on the portfolio risk weighted by risk aversion. For an identical portfolio, the investor with a higher risk aversion (A) would calculate a lower utility (U). U=E(r) −1/2 * Aσ
With respect to risk-averse investors, a risk-free asset will generate a numerical utility that is
the same for all individuals.
positive for risk-averse investors.
equal to zero for risk seeking investors.
the same for all individuals.
With respect to an investor’s utility function expressed as: U=E(r)−12Aσ2
, which of the following values for the measure for risk aversion has the least amount of risk aversion?
−4.
0.
4.
-4
With respect to the mean–variance portfolio theory, the capital allocation line, CAL, is the combination of the risk-free asset and a portfolio of all:
risky assets.
equity securities.
feasible investments.
risky assets.
The CAL is the combination of the risk-free asset with zero risk and the portfolio of all risky assets that provides for the set of feasible investments. Allowing for borrowing at the risk-free rate and investing in the portfolio of all risky assets provides for attainable portfolios that dominate risky assets below the CAL
Two individual investors with different levels of risk aversion will have optimal portfolios that are:
below the capital allocation line.
on the capital allocation line.
above the capital allocation line.
The CAL represents the set of all feasible investments. Each investor’s indifference curve determines the optimal combination of the risk-free asset and the portfolio of all risky assets, which must lie on the CAL.
The CAL represents the set of all
feasible investments
What is beta of By definition, a short-term US Treasury bill ?
By definition, a short-term US Treasury bill has zero risk. Therefore, its beta is zero.
Portfolios are most likely to provide:
risk reduction.
risk elimination.
downside protection.
A is correct. Combining assets into a portfolio should reduce the portfolio’s volatility. However, the portfolio approach does not necessarily provide downside protection or eliminate all risk.
Which of the following biases least likely relates to the mental discomfort that occurs when new information conflicts with a set of initial beliefs?
A. Confirmation bias
B. Representativeness bias
C. Anchoring and adjustment bias
Belief perseverance biases relate to cognitive dissonance, the mental discomfort when an investor is given new information that conflicts with prior beliefs. Biases in this category include:
Conservatism bias
Confirmation bias
Representativeness bias
Illusion of control bias
Hindsight bias
Anchoring and adjustment bias is a type of processing error bias.
un Park, CFA, works at a hedge fund. Most of Park’s colleagues are also CFA charterholders. At an event with recent university graduates, Park comments, “Most CFA charterholders work at hedge funds.” Park’s remark exhibits which behavioral bias?
A Availability
B Conservatism
C Framing
A is correct. Park is extrapolating his observation based on a narrow range of experience (working at a hedge fund that employs many CFA charterholders) to the entire population of CFA charterholders. Using a narrow range of experience is a form of availability bias.
Which of the following is not a goal of risk management?
A.Measuring risk exposures
B.Minimizing exposure to risk
C.Defining the level of risk appetite
B is correct. The definition of risk management includes both defining the level of risk desired and measuring the level of risk taken. Risk management means taking risks actively and in the best, most value-added way possible and is not about minimizing risks.
Which element of a risk management framework sets the overall context for risk management in an organization?
Governance
Risk infrastructure
Policies and processes
A is correct. Governance is the element of the risk management framework that is the top-level foundation for risk management. Although policies, procedures, and infrastructure are necessary to implement a risk management framework, it is governance that provides the overall context for an organization’s risk management
Which element of risk management makes up the analytical component of the process?
Communication
Risk governance
Risk identification and measurement
C is correct. Risk identification and measurement is the quantitative part of the process. It involves identifying the risks and summarizing their potential quantitative impact. Communication and risk governance are largely qualitative.
Which element of risk management involves action when risk exposures are found to be out of line with risk tolerance?
Risk governance
Risk identification and measurement
Risk monitoring, mitigation, and management
C is correct. Risk monitoring, mitigation, and management require recognizing and taking action when these (risk exposure and risk tolerance) are not in line, as shown in the middle of Exhibit 1. Risk governance involves setting the risk tolerance. Risk identification and measurement involves identifying and measuring the risk exposures.
Which of the following is not consistent with a risk-budgeting approach to portfolio management?
Limiting the beta of the portfolio to 0.75
Allocating investments by their amount of underlying risk sources or factors
Limiting the amount of money available to be spent on hedging strategies by each portfolio manager
C is correct. Risk budgeting is any means of allocating a portfolio by some risk characteristics of the investments. This approach could be a strict limit on beta or some other risk measure or an approach that uses risk classes or factors to allocate investments. Risk budgeting does not require nor prohibit hedging, although hedging is available as an implementation tool to support risk budgeting and overall risk governance.
Who would be the least appropriate for controlling the risk management function in a large organization?
Chief risk officer
Chief financial officer
Risk management committee
B is correct. A chief risk officer or a risk management committee is an individual or group that specializes in risk management. A chief financial officer may have considerable knowledge of risk management, may supervise a CRO, and would likely have some involvement in a risk management committee, but a CFO has broader responsibilities and cannot provide the specialization and attention to risk management that is necessary in a large organization.
Which of the following best describes a financial risk?
The risk of an increase in interest rates.
The risk that regulations will make a transaction illegal.
The risk of an individual trading without limits or controls.
A is correct because this risk arises from the financial markets.
Which of the following is not an example of model risk?
Assuming the tails of a returns distribution are thin when they are, in fact, fat.
Using standard deviation to measure risk when the returns distribution is asymmetric.
Using the one-year risk-free rate to discount the face value of a one-year government bond.
C is correct. The risk-free rate is generally the appropriate rate to use in discounting government bonds. Although government bonds are generally default free, their returns are certainly risky. Assuming a returns distribution has thin tails when it does not and assuming symmetry in an asymmetric distribution are both forms of model risk.
The risks that individuals face based on mortality create which of the following problems?
The risk of loss of income to their families.
Covariance risk associated with their human capital and their investment portfolios.
The interacting effects of solvency risk and the risk of being taken advantage of by an unscrupulous financial adviser.
A is correct. The uncertainty about death creates two risks: mortality risk and longevity risk. The mortality risk (risk of dying relatively young) is manifested by a termination of the income stream generated by the person. In contrast, longevity risk is the risk of outliving one’s financial resources.
The best definition of value at risk is:
the expected loss if a counterparty defaults.
the maximum loss an organization would expect to incur over a holding period.
the minimum loss expected over a holding period a certain percentage of the time.
C is correct. VaR measures a minimum loss expected over a holding period a certain percentage of the time. It is not an expected loss, nor does it reflect the maximum possible loss, which is the entire equity of the organization.
Which of the following are methods commonly used to supplement VaR to measure the risk of extreme events?
Standard deviation
Loss given default
Scenario analysis and stress testing
C is correct. Scenario analysis and stress testing both examine the performance of a portfolio subject to extreme events. The other two answers are metrics used in portfolio analysis but are not typically associated with extreme events.
Which of the following is a true statement about insurable risks?
Insurable risks are less costly.
Insurable risks have smaller loss limits.
Insurable risks are typically diversifiable by the insurer.
C is correct. Insurance works by pooling risks. It is not necessarily less costly than derivatives nor does it have lower loss limits.
Which of the following performance measures is consistent with the CAPM?
M^2.
Sharpe ratio.
Jensen’s alpha.
C is correct. Jensen’s alpha adjusts for systematic risk, and M^2 and the Sharpe Ratio adjust for total risk.
Which of the following performance measures does not require the measure to be compared to another value?
Sharpe ratio.
Treynor ratio.
Jensen’s alpha.
C is correct. The sign of Jensen’s alpha indicates whether or not the portfolio has outperformed the market. If alpha is positive, the portfolio has outperformed the market; if alpha is negative, the portfolio has underperformed the market.
Which of the following performance measures is most appropriate for an investor who is not fully diversified?
M2.
Treynor ratio.
Jensen’s alpha.
A is the correct. M2 adjusts for risk using standard deviation (i.e., total risk).
The portfolio of a risk-free asset and a risky asset has a better risk-return tradeoff than investing in only one asset type because the correlation between the risk-free asset and the risky asset is equal to:
−1.0.
0.0.
1.0.
B is correct. A portfolio of the risk-free asset and a risky asset or a portfolio of risky assets can result in a better risk-return tradeoff than an investment in only one type of an asset, because the risk-free asset has zero correlation with the risky asset.
With respect to capital market theory, an investor’s optimal portfolio is the combination of a risk-free asset and a risky asset with the highest:
expected return.
indifference curve.
capital allocation line slope.
B is correct. Investors will have different optimal portfolios depending on their indifference curves. The optimal portfolio for each investor is the one with highest utility; that is, where the CAL is tangent to the individual investor’s highest possible indifference curve.
Which of the following statements most accurately defines the market portfolio in capital market theory? The market portfolio consists of all:
risky assets.
tradable assets.
investable assets.
A is correct. The market includes all risky assets, or anything that has value; however, not all assets are tradable, and not all tradable assets are investable.
With respect to the pricing of risk in capital market theory, which of the following statements is most accurate?
All risk is priced.
Systematic risk is priced.
Nonsystematic risk is priced.
B is correct. Only systematic risk is priced. Investors do not receive any return for accepting nonsystematic or diversifiable risk.
A return-generating model that provides an estimate of the expected return of a security based on such factors as earnings growth and cash flow generation is best described as a
fundamental factor
With respect to the capital asset pricing model, the market risk premium is:
less than the excess market return.
equal to the excess market return.
greater than the excess market return.
B is correct. In the CAPM, the market risk premium is the difference between the return on the market and the risk-free rate, which is the same as the return in excess of the market return.
With respect to capital market theory, which of the following assumptions allows for the existence of the market portfolio? All investors:
are price takers.
have homogeneous expectations.
plan for the same, single holding period.
B is correct. The homogeneous expectations assumption means that all investors analyze securities in the same way and are rational. That is, they use the same probability distributions, use the same inputs for future cash flows, and arrive at the same valuations. Because their valuation of all assets is identical, they will generate the same optimal risky portfolio, which is the market portfolio.
Which of the following portfolio performance measures are the most appropriate for an investor who holds a fully diversified portfolio?
Sharpe ratio and Treynor ratio.
Treynor ratio and Jensen’s alpha.
M-Squared and Sharpe ratio.
Correct. For an investor who holds a fully diversified portfolio, the Treynor ratio and Jensen’s alpha are the appropriate portfolio performance measures. They are appropriate because in a fully diversified portfolio, only systematic risk matters; both these metrics measure performance relative to beta or systematic risk.
Portfolio managers, who are maximizing risk-adjusted returns, will seek to invest less in securities with:
lower values for nonsystematic variance.
values of nonsystematic variance equal to 0.
higher values for
nonsystematic variance.
C is correct. Since managers are concerned with maximizing risk-adjusted returns, securities with greater nonsystematic risk should be given less weight in the portfolio.
Which of the following is the best reason for an investor to be concerned with the composition of a portfolio?
Risk reduction.
Downside risk protection.
Avoidance of investment disasters.
A is correct. Combining assets into a portfolio should reduce the portfolio’s volatility. The portfolio approach does not necessarily provide downside protection or guarantee that the portfolio always will avoid losses
With respect to the formation of portfolios, which of the following statements is most accurate?
Portfolios affect risk less than returns.
Portfolios affect risk more than returns.
Portfolios affect risk and returns equally.
B is correct. As illustrated in the reading, portfolios reduce risk more than they increase returns.
