An efficient capital market is best defined as a market in which security prices reflect which one of the following?
Multiple Choice
A Current inflation
B A risk premium
C All available information
D The historical arithmetic rate of return
E The historical geometric rate of return
1. What are the recommended options strategies when you expect the market has extreme (high) volatility?
6. Equilibrium pricing: Let the subscripts: j = 0 denote the risk-free asset, j = 1,...,n the set
of available risky securities, and M the market portfolio. For the questions that follow,
assume that CAPM provides an accurate description of reality.
a.
b.
C.
d.
State the CAPM equation. (1)
Use the CAPM equation to show that the following condition is true s; ≤ SM
for any j. What is the significance of this condition when interpreted in the
context of the capital market line? (5)
Assume that B = 0.8, μM = 0.1 and r = 0.05. Using the CAPM, determine
the expected return from holding one unit of asset j for one
period. (2)
Given your answer to c.), what could you conclude (from the perspective of
the security market line) if a market survey indicated that the forecasted one-
period return on asset j was 8 percent? Describe and motivate the rational
trading response that is consistent with your conclusion. (4)

- Suppose the solid line represents the capital market line that results from a CAPM equilibrium and the dotted curves represent indifference curves for a given individual. Which of the following is correct if point M corresponds to the market portfolio? Group of answer choices The individual optimally holds only the market portfolio, M. The individual optimally holds portfolio B which can be partially characterized by a long position in the riskless asset. The individual optimally holds portfolio B which can be partially characterized by a short position in the riskless security The individual optimally holds portfolio A which can be partially characterized by a long position in the riskless security. None of the above.arrow_forwardWhich of the following statements about the Security Market Line are correct? I. The intercept point is the market rate of return. II. The slope of the line is beta. III. An investor should accept any return located above the SML line. IV. A beta of 0.0 indicates the risk-free rate of returnarrow_forwardA zero-investment portfolio with a positive alpha could arise if:a. The expected return of the portfolio equals zero.b.

- Which of the following is TRUE? To construct a capital market line, we use expected return as y-axis and beta as x-axis On the capital market line debt securities are located to the right of the market portfolio To construct a security market line, we use expected return as y-axis and beta as x-axis Market portfolio lays at an intersection of the average indifference curve of a risk-averse investor and the efficient portfolioarrow_forwardplease answer both. If a stock's fair return increases, what will happen to the stock's value? A. It will increase. B. It will not change. C. It will decrease. If the market risk premium rises, what will happen to the stock's price? A. It will not change. B. It will increase. C.

- We believe that the single factor model can predict any individual asset’s realized rate of return well. Both Portfolio A and Portfolio B are well-diversified: ri = E(ri) + βiF + Ei, where E(ei) = 0 and Cov(F, i) = 0 A B β 1.2 0.8 E(r) 0.1 0.08 (1) What is the rate of return of the risk-free asset? (2) What is the expected rate of return of the well-diversified portfolio C with βC = 1.6, which also exists in the market? (3) A fund constructs a well-diversified portfolio D. Studies show that βD = 0.6. The expected rate of return of D is 0.06. Is there an arbitrage opportunity? If so, construct a trading strategy to earn profits with no risk. If not, why?arrow_forwardAn investor is considering two possible investment alternatives, Portfolio A and Portfolio B. The expected returns for each are shown in the table below under two different market conditions, along with the investors prediction for the probability of each market condition. The investor's prediction for the probability of each market condition. The investor's utility function can be represented as U(w) - square root (w). If the investor maximises their expected utility, which alternative would they choose? Portfolio A Portfolio B Bull Market Bear Market Portfolio A 16% Portfolio B 4% Probability 0.75 3% 2% 0.25arrow_forwardTick all those statements on arbitrage that are correct (and don't tick those that are incorrect). a. When constructing suitable betting strategies, the number m of outcomes of an event and the number ʼn of possible wagers are always the same. b. The arbitrage theorem essentially tells us that either there exists a risk-neutral distribution or there is an arbitrage opportunity. c. If there is an arbitrage opportunity then this implies that a risk-neutral distribution exists. d. In real markets there are ocasionally small arbitrage opportunities due to lack of information. e. If there is a sporting event with 3 different outcomes which have the odds 0₁ = 1, 2, 3 then there is an arbitrage opportunity for a suitable betting strategy.arrow_forward
