risk factors common to the whole economy; also called systematic or nondiversifiable risk
define illiquidity
difficulty, cost, and/or delay in selling an asset on short notice without offering substantial price concessions
define diversification
spreading a portfolio over many investments to avoid excessive exposure to any one source of risk

spreading risk across many investors so that each investor bears only a fraction of the total risk
define alpha
the abnormal rate of return on a security in excess of what would be predicted by an equilibrium model like the CAPM
define homogeneous expectations
the assumption that all investors agree on the probability distribution of future returns, so they all use the same input list
define capital market line (CML)
the capital allocation line that results when using the market index as the risky portfolio

Kaskin, Inc., stock has a beta of 1.2 and Quinn, Inc., stock has a beta of .6. Which of the following statements is most accurate? a. the expected rate of return will be higher for the stock of Kaskin, Inc., than that of Quinn, Inc. b. the stock of Kaskin, Inc., has more total risk than the stock of Quinn, Inc. c. The stock of Quinn, Inc., has more systematic risk thatn that of Kaskin, Inc.
A, Beta is a measure of systematic risk. Since only systematic risk is rewarded, it is safe to conclude that the expected return will be higher for Kaskin's stock than for Quinn's stock.
What is the expected rate of return for a stock that has a beta of 1.0 if the expected return on the market is 15%? a. 15% b. more than 15% c. cannot be determined without the risk-free rate
A, The expected return of a stock with a β = 1.0 must, on average, be the same as the expected return of the market which also has a β = 1.0.
Which one of the following portfolios cannot lie on the efficient frontier as described by Markowitz? Portfolio E(r) Standard Deviation W 9% 21% X 5% 7% Y 15% 36% Z 12% 15% 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 be determined from the information given.
Answer A, 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.
The correlation coefficients between several pairs of stocks are as follows: Corr(A, B) = 0.85; Corr(A, C) = 0.60; Corr(A, D) = 0.45. Each stock has an expected return of 8% and a standard deviation of 20%. If your entire portfolio is now composed of stock A and you can add some of only one stock to your portfolio, would you choose: a. B b. C c. D d. need more data
Answer is c, The correct choice is Stock D. Intuitively, we note that since all stocks have the same expected rate of return and standard deviation, we choose the stock that will result in lowest risk. This is the stock that has the lowest correlation with Stock A.
what do you think would happen to the expected return on stocks if investors perceived higher volatility in the equity market? relate your answer to equation 6.7 y* = E(rp) -rf / AO^2p
Assuming no change in risk tolerance, that is, an unchanged risk-aversion coefficient (A), higher perceived volatility increases the denominator of the equation for the optimal investment in the risky portfolio (Equation 6.7). The proportion invested in the risky portfolio will therefore decreases
T/F: stocks with a beta of zero offer an expected rate of return of zero
False, . β = 0 implies E(r) =rf, not zero
T\F: The CAPM implies that investors require a higher rate of return to hold highly volatile securities
False, Investors require a risk premium only for bearing systematic (undiversifiable or market) risk. Total volatility, as measured by the standard deviation, includes diversifiable risk
consider a portfolio that offers an expected rate of return 12%, standard deviation of 18% and t-bills offer a risk free 7% rate of return. What is the maximum level of risk aversion for which the risky portfolio is still preferred to T-bills?
U = E(r) - 0.5Aσ^2 The utility level for the risky portfolio is:U = 0.12 - 0.5 ×A × (0.18)2= 0.12 - 0.0162 ×A In order for the risky portfolio to be preferred to bills, the following must hold: 0.12 - 0.0162A > 0.07A <05/0.0162 = 3.09 A must be less than 3.09 for the risky portfolio to be preferred to bills
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 return 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.

define passive strategy
a portfolio decision that avoids any direct or indirect security analysis.
define mutual fund theoreum
a result associated with the CAPM, asserting that investors will choose to invest their entire risky portfolio in a market-index mutual fund
consider a risky portfolio. the end-of-the-year flow derived from the portfolio will be either $70,000 or $200,000 with equal probabilities of .5. The alternative risk-free investment in T-bills pays 6% per year. a. if you require a risk premium of 8%. how much will you be willing to pay for the portfolio? b. suppose that the portfolio can be purchases for the amount you found in (a). what will be the expected rate of return on the portfolio? c. now suppose that you require a risk premium of 12%. What is the price that you will be willing to pay? d. comparing your answers to (a) and (c), what do you conclude about the relationship between the required risk premium on a portfolio and the price at which the portfolio will sell?
a.((0.5*70000)+(0.5*200000))/(1+14%) =118421 b. 118421*(1+E(r)) =135000 Therefore, E(r) =14%. The portfolio price is set to equate the expected rate of return with the required rate of return. c. 6+12 = 18% 135000/(1+.18)=114407 d. For a given expected cash flow, portfolios that command greater risk premiums must sell at lower prices. The extra discount from expected value is a penalty for risk
define risk-free asset

define risk lover
an investor who is willing to accept lower expected returns on prospects with higher amounts of risk
define risk averse
an investor who will consider risky portfolios only if they provide compensation for risk via a risk premium
define optimal risky portfolio
an investor's best combination of risky assets; the combination that maximizes the Sharpe ratio

T/F: the standard deviation of the portfolio is always equal to the weighted average of the standard deviations of the assets in the portfolio
false
t/f: assume that expected returns and standard deviations for all securities (including the risk-free rate for borrowing and lending) are known. In this case, all investors will have the same optimal risky portfolio.
false
t/f: The CAPM implies that investors require a higher return to hold highly volatile securities
false, Investors require a risk premium only for bearing systematic (undiversifiable or market) risk. Total volatility, as measured by the standard deviation, includes diversifiable risk.
t/f: you can construct a portfolio with beta of 0.75 by investing 0.75 of the investment budget in T-bills and the remainder in the market portfolio.
false, Your portfolio should be invested 75% in the market portfolio and 25% in T-bills. Then: βP = (0.75 × 1) + (0.25 × 0) = 0.75
T/F: you can construct a portfolio with beta of .75 by investing .75 of the investment budget in T-bills and the remainder in the market portfolio
false, e. Your portfolio should be invested 75% in the market portfolio and 25% in T-bills. Then: β=(0.75 1) (0.25 0) 0.75
