Which of the following are consistent with the efficient market hypothesis? Check all that apply.
Changes in stock prices can be accurately predicted by investors.
At the market price, the number of people who believe the stock is overvalued exactly equals the number of people who think the stock is undervalued.
A positive news release about a company will increase the value and stock price for that firm.
Some investors cite the existence of anomalies—observations that do not fit the model—as evidence that stock markets are not efficient. Which of the following are such anomalies? Check all that apply.
The best time to sell a stock is late on Wednesday or Friday, whereas the best time to buy a stock is late on Tuesday or Thursday.
The movement of stock prices of companies over time is the same as the changes in their earnings.
High returns to a stock in one period are associated with even higher returns in a later period.

A study analyzed the behavior of the stock prices of firms that had lost antitrust cases. Included in the diagram are all firms that lost the initial court decision, even if the decision was later overturned on appeal. The event at Time 0 is the initial, pre-appeal court decision. Assume no other information was released, aside from that disclosed in the initial trial. The stock prices all have a beta of 1. Is the diagram consistent with market efficiency? Why or why not?
Which of the following is NOT a potential problem when estimating and using betas, i.e., which statement is FALSE?
a. Sometimes, during a period when the company is undergoing a change such as toward more leverage or riskier assets, the calculated beta will be drastically different from the "true" or "expected future" beta.
b. The beta of an "average stock," or "the market," can change over time, sometimes drastically.
c. Sometimes the past data used to calculate beta do not reflect the likely risk of the firm for the future because conditions have changed.
d. All of the statements above are true.
e. The fact that a security or project may not have a past history that can be used as the basis for calculating beta.

- Which of the following empirical observations appear to contradict weak form market efficiency? a. 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. A strategy of buying recent high-return stocks (winners) and shorting recent low-return stocks (losers) provides significant positive alpha d. Low dividend stocks provide higher-than-average capital gains e. None of the abovearrow_forwardSay stocks of firms which change their logo in a given year tend to outperform (have higher abnormal returns) the stocks of firms which don't change their logos for the following year. If markets are efficient and you used the correct model for expected returns in your analysis, what must be true about firms that change their logos relative to firms that don't change their logos? Firms that change their logos are more exposed to risk than firms that don't change their logos. Firms that change their logos are equally exposed to risk as firms that don't change their logos. Firms that change their logos are less exposed to risk than firms that don't change their logos. O We can't make any of the above statementsarrow_forward5. Which of the following statements about event studies is/are true? (a) Event time is measured relative to the date on which the event (e.g. the stock split) is first announced to the market. (b) CAAR stands for Cumulative Average Abnormal Return. (c) Abnormal returns are always measured as the return over and above the Capital Asset Pricing Model. * (a) only. (b) only. (c) only.

- Which of the following statements is CORRECT? a. The SML shows the relationship between companies' required returns and their diversifiable risks. The slope and intercept of this line cannot be influenced by a firm's managers, but the position of the company on the line can be influenced by its managers. b. Suppose you plotted the returns of a given stock against those of the market, and you found that the slope of the regression line was negative. The CAPM would indicate that the required rate of return on the stock should be less than the risk-free rate for a well-diversified investor, assuming investors expect the observed relationship to continue on into the future. c. If investors become less risk averse, the slope of the Security Market Line will increase. d. If a company increases its use of debt, this is likely to cause the slope of its SML to increase, indicating a higher required return on the stock. e. The slope of the SML is determined by the value of beta.arrow_forwardThe 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_forwardSuppose 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? Explain.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_forward

- Which is true in relation to stock market efficiency? A.Market Price and Intrinsic value are inputs in determining whether a share is overvalued or undervalued B. If markets are truly efficient, each share prices should have a high deviation from its intrinsic value C. Intrinsic Value is readily observed from the stock market daily reports D. Large companies which is followed by many analyst are generally considered as highly inefficientarrow_forwardMany financial economists believe that the random walk model is a gooddescription of the logarithm of stock prices. It implies that the percentagechanges in stock prices are unforecastable. A financial analyst claims to havea new model that makes better predictions than the random walk model.Explain how you would examine the analyst’s claim that his model is superior?arrow_forwardBased on the CAPM, Jensen's Alpha of a firm a) equals zero if the firm's stock returns have underperformed as compared to the market after adjusting for its beta risk. b) is positive if the firm's stock returns have overperformed as compared to the market after adjusting for its beta risk. c) is negative if the firm's stock returns have overperformed as compared to the market after adjusting for its beta risk. d) equals one if the firm's stock returns have underperformed as compared to the market after adjusting for its beta risk.arrow_forward
