Historical VaR simulation involves using past data as a guide to what will happen in the future. B. Illiquidity is observed when there is a large difference between the offered sale price and the bid price. C. Yield spared is reflected in the size of the bid-ask spreads. D. The stressed VaR is based on how market variables have moved during a particularly adverse time period.arrow_forwardConsider the two (excess return) index model regression results for A and B. RA= 0.9% + 1.1RM , R-square = 0.590, and Residual Standard Deviation = 11% RB= -1.4% + 0.6RM, R-square = 0.456, and Residual Standard Deviation = 9.2% Which stock has more firm-specific risk, market risk, and greater fraction of return variability for market movement?

- The efficient markets hypothesis identifies three forms of market efficiency. (a) You observed that high-level managers make superior returns on investments in their company’s stock. Would this be a violation of weak-form market efficiency? Would it be a violation of strong-form market efficiency? (b) If the weak form of the efficient market hypothesis is valid, must the strong form also hold? Conversely, does strong form efficiency imply weak form efficiency? (c) Stock XYZ, which traded for several months at a price of K72, and then declines to K65. if the stock eventually begins to increase in price, K72 is considered a resistance level because investors who bought originally at K72 will be eager to sell their shares as soon as they can break even on their investment. If everyone in the market believes in resistance levels, why do these beliefs not become self-fulfilling prophecies?arrow_forwardPlease answer both QUESTION 5 Which of the following is not a reason why beta may differ between sources: Beta is based on historical values.

The average rate of return of stocks is significantly greater than zero b. The month-to-month time series autocorrelation of stock returns is not significantly different from zero c.

- Suppose that, after conducting an analysis of past stock prices, you come up with the following observations. Which would appear to contradict the weak form of the efficient market hypothesis? A. The average rate of return is significantly greater than zero. B. The correlation between the return during a given week and the return during the following week is zero. C. One could have made superior returns by buying stock after a 10% rise in price and selling after a 10% fall. D. One could have made higher-than-average capital gains by holding stocks with low dividend yields.arrow_forwardWhich of the following statements is false? A. The lower the correlation coefficient, the greater the potential benefits from diversification. B. To make the covariance of two random variables easier to interpret, it may be divided by the product of the random variables’ standard deviation.

In the event of bankruptcy, preferred stock ranks below common stock but above debt.arrow_forwardWhich of the following statements is most correct? Why?* a.
