Textbook Question
Chapter 14, Problem 10CQ
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 arc 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.
Use the following information for the next two questions:
Technical analysis is a controversial investment practice. Technical analysis covers a wide array of techniques, which arc all used in an attempt to predict the direction of a particular stock or the market. Technical analysts look at two major types of information: Historical stock prices and investor sentiment. A technical analyst would argue these two information sets provide information about the future direction of a particular stock or the market as a whole.

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. Use the following information for the next two questions:

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_forwardMarket equity beta measures the covariability of a firms returns with all shares traded on the market (in excess of the risk-free interest rate). We refer to the degree of covariability as systematic risk. The market prices securities so that the expected returns should compensate the investor for the systematic risk of a particular stock. Stocks carrying a market equity beta of 1.20 should generate a higher return than stocks carrying a market equity beta of 0.90. Nonsystematic risk is any source of risk that does not affect the covariability of a firms returns with the market. Some writers refer to nonsystematic risk as firm-specific risk. Why is the characterization of nonsystematic risk as firm-specific risk a misnomer?arrow_forward
- Investment advisors estimated the stock market returns for four market segments: computers, financial, manufacturing, and pharmaceuticals. Annual return projections vary depending on whether the general economic conditions are improving, stable, or declining. The anticipated annual return percentages for each market segment under each economic condition are as follows: Assume that an individual investor wants to select one market segment for a new investment. A forecast shows improving to declining economic conditions with the following probabilities: improving (0.2), stable (0.5), and declining (0.3). What is the preferred market segment for the investor, and what is the expected return percentage? At a later date, a revised forecast shows a potential for an improvement in economic conditions. New probabilities are as follows: improving (0.4), stable (0.4), and declining (0.2). What is the preferred market segment for the investor based on these new probabilities? What is the expected return percentage?arrow_forwardNow assume that the stock is currently selling at $30.29.

Based on the beta, how would you expect the stock's returns to react to a decrease in returns in the market overall? Why? C.
