Jeffrey Bruner, CFA, uses the capital asset pricing model (CAPM) to help identify mispriced securities. A consultant suggests Bruner use arbitrage pricing theory (APT) instead. In comparing CAPM and APT, the consultant makes the following arguments:a. Both the CAPM and APT require a mean-variance efficient market portfolio.b. Neither the CAPM nor the APT assumes normally distributed security returns.c. The CAPM assumes that one specific factor explains security returns but APT does not.State whether each of the consultant’s arguments is correct or incorrect. Indicate, for each incorrect argument, why the argument is incorrect.
Which of the following is NOT an assumption used in deriving the Capital Asset Pricing Model (CAPM)?
Investors can buy and sell all securities at competitive market prices without incurring taxes or transactions cost and can borrow and lend at the risk-free interest rate
Investors hold only efficient portfolios of traded securities.
Investors have homogeneous expectations regarding the volatilities, correlation, and expected returns of securities.
Investors have homogeneous risk averse preferences toward taking on risk.
Richard Roll, in an article on using the capital asset pricing model (CAPM) to evaluate portfolio performance, indicated that it may not be possible to evaluate portfolio management ability if there is an error in the benchmark used.a. In evaluating portfolio performance, describe the general procedure, with emphasis on the benchmark employed.b. Explain what Roll meant by benchmark error and identify the specific problem with this benchmark.c. Draw a graph that shows how a portfolio that has been judged as superior relative to a “measured” security market line (SML) can be inferior relative to the “true” SML.d. Assume that you are informed that a given portfolio manager has been evaluated as superior when compared to the Dow Jones Industrial Average, the S&P 500, and the NYSE Composite Index. Explain whether this consensus would make you feel more comfortable regarding the portfolio manager’s true ability.e. Although conceding the possible problem with benchmark errors as set forth…

- You have been hired at the investment firm of Bowers Noon. One of its clients doesnt understand the value of diversification or why stocks with the biggest standard deviations dont always have the highest expected returns. Your assignment is to address the clients concerns by showing the client how to answer the following questions: d. Construct a plausible graph that shows risk (as measured by portfolio standard deviation) on the x-axis and expected rate of return on the y-axis. Now add an illustrative feasible (or attainable) set of portfolios and show what portion of the feasible set is efficient. What makes a particular portfolio efficient? Dont worry about specific values when constructing the graphmerely illustrate how things look with reasonable data.arrow_forwardYou have been hired at the investment firm of Bowers & Noon. One of its clients doesn’t understand the value of diversification or why stocks with the biggest standard deviations don’t always have the highest expected returns. Your assignment is to address the client’s concerns by showing the client how to answer the following questions: Suppose a risk-free asset has an expected return of 5%. By definition, its standard deviation is zero, and its correlation with any other asset is also zero. Using only Asset A and the risk-free asset, plot the attainable portfolios.arrow_forwardYou have been hired at the investment firm of Bowers & Noon.

Select one: securities are in equilibrium prices fully reflect all public information available the investors should not waste their time on under- or over-valued securities None of the answers are correct the market has demonstrated that stocks are not reasonably priced.arrow_forwardAccording to the capital asset pricing model (CAPM), fairly priced securities should have __________.

- Mark thinks that there is an interesting paradox of the efficient market hypothesis. If the market believes that prices reflect all information, investors will stop seeking mispriced securities. This may lead to more mispriced stocks and more inefficiency. However, if the market believes that inefficiency still exists, the competition of trying to be the first to find mispriced securities will make markets more efficient. Do you agree with Mark? Why or why not? Please briefly comment.arrow_forwardWhich is correct about security valuation? A. In an efficient market, several factors would affect the market and value is not necessarily equals the price. B. The value of the security is determined to compare it with the current market price and usually investor would buy when the value equals the price. C. Sellers would prefer the accept lower bid price than higher bid price to realize gains. D. Investors buy securities when securities are underpriced and sell them when it is overpriced. E. All of the above F. None of the abovearrow_forwardIn a seminal article on portfolio theory, Markowitz (1952) illustrated that investors are not compensated for taking on firm specific or idiosyncratic risk; however, they are compensated for taking market or systemic risk. Use your understanding of the Capital Asset Pricing Model (CAPM), statistical concepts such as standard deviation and variance, and our ideas about market efficiency and indicate whether you believe that this is a good theory. Include at least two citations that support your response.arrow_forward
- Arbitrage is the idea that one can (select the best answer): Group of answer choices Buy and Sell different assets or packages of assets at different prices such you can earn a riskless profit without investing any capital. Earn rates of return greater than the average for the market by successfully “picking” stocks. Earn abnormal returns above what CAPM would predict for a particular security.arrow_forwardBart Campbell, CFA, is a portfolio manager who has recently met with a prospective client, Jane Black. After conducting a survey market line (SML) performance analysis using the Dow Jones Industrial Average as her market proxy, Black claims that her portfolio has experienced superior performance. Campbell uses the capital asset pricing model as an investment performance measure and finds that Black’s portfolio plots below the SML. Campbell concludes that Black’s apparent superior performance is a function of an incorrectly specified market proxy, not superior investment management. Justify Campbell’s conclusion by addressing the likely effects of an incorrectly specified market proxy on both beta and the slope of the SML.arrow_forwardWhich is true with regards to the systematic and unsystematic risk? To mitigate the unsystematic risk, an investor must choose two stocks that has a perfectly negative correlation when establishing ones portfolio of securities A portfolio with stocks that has high Sharpe ratios does not have both unsystematic and systematic risk because then generate excess returns The likes of inflation, recession, changes in interest rates are examples of market risk that can be reduced to zero by a portfolio that is fully diversified Systematic risk can be diversified by choosing stocks that has a small standard deviation but high correlation coefficient since these stocks are less riskierarrow_forward
