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 contradicts weak form efficiency?
Group of answer choices
1- Stock prices do not reflect information that is only available to insiders.
2- Good or bad recent stock return performance continues over the next three months.
3- The cumulative abnormal returns continue to increase until six months after a firm announces a good unexpected earnings.
4- Technical analysis could not provide abnormal returns. Fundamental analysis could not provide abnormal returns.
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?

- Efficient Market Hypothesis For each of the following scenarios, discuss whether profit opportunities exist from trading in the stock of the firm under the conditions that (1) the market is not weak form efficient, (2) the market is weak form but not semistrong form efficient, (3) the market is semistrong form but not strong form efficient, and (4) the market is strong form efficient. a. The stock price has risen steadily each day for the past 30 days.b. The financial statements for a company were released three days ago, and you believe you’ve uncovered some anomalies in the company’s inventory and cost control reporting techniques that are causing the firm’s true liquidity strength to be understated. c. You observe that the senior management of a company has been buying a lot of the company’s stock on the open market over the past week.

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.

- [Results] shows that corporate net optimistic tone, executive net optimistic tone and governance net optimistic tone are positively associated with future market performance, however, they are not significant. These results are consistent with Wisniewski and Yekini (2015) when they found optimism in annual reports narratives is positive but not significant with future stock returns. In addition, our results are in line with prior studies that found positive tone is not significant with stock market reaction in the long term (Arslan-Ayaydin et al. 2016; Huang et al. 2014). The current research aims to examine not only narrative tone predictive power but also who has this predictive power inside the company (executives or governance). It is expected that both groups will not have the same tone consistency in their narrative reporting as they have different responsibilities. Executives are responsible for providing a fair view about companies’ performance and future strategies, whereas,…arrow_forwardA support level is the price range at which a technical analyst would expect the A) supply of a stock to increase dramatically.
