Several celebrated investors and stock pickers have recorded huge returns on their investments over the past two decades. Is the success of these particular investors an invalidation of an efficient stock market? Explain.
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?
Investment Performance. It seems that every month we read an article in The Wall Street Journal about a stock picker with a marvelous track record. Do these examples mean that financial markets are not efficient?

- Using Past Information to Estimate Required Returns Use online resources to work on this chapter's questions. Please note that website information changes over time, and these changes may limit your ability to answer some of these questions. Chapter 8 discussed the basic trade-off between risk and return. In the capital asset pricing model (CAPM) discussion, beta was identified as the correct measure of risk for diversified shareholders. Recall that beta measures the extent to which the returns of a given stock move with the stock market. When using the CAPM to estimate required returns, we would like to know how the stock will move with the market in the future, but because we dont have a crystal ball, we generally use historical data to estimate this relationship with beta. As mentioned in Web Appendix 8A, beta can be estimated by regressing the individual stock's returns against the returns of the overall market. As an alternative to running our own regressions, we can rely on reported betas from a variety of sources. These published sources make it easy for us to readily obtain beta estimates for most large publicly traded corporations. However, a word of caution is in order. Beta estimates can often be quite sensitive to the time period in which the data are estimated, the market index used, and the frequency of the data used. Therefore, it is not uncommon to find a wide range of beta estimates among the various Internet websites. 4.

False True Almost all financial theory and decision models assume that the financial markets are efficient. The informational efficiency of financial markets determines the ability of investors to “beat” the market and earn excess (or abnormal) returns on their investments. If the markets are efficient, they will react rapidly as new relevant information becomes available. Financial theorists have identified three levels of informational efficiency that reflect what information is incorporated in stock prices. Identify the form of capital market efficiency under the efficient market hypothesis described in the following statement: Current market prices reflect all information contained in past price movements. This statement is consistent with: Strong form efficiency Semistrong form efficiency Weak form efficiency…arrow_forward

Instead of running for the exits during times of market stress, the smart investor greets downturns as chances to find great investments. Graham illustrated this with the analogy of "Mr. Market," the imaginary business partner of each and every investor. Mr. Market offers investors a daily price quote at which he would either buy an investor out or sell his share of the business. Sometimes, he will be excited about the prospects for the business and quote a high price. Other times, he is depressed about the business's prospects and quotes a low price.arrow_forward

- In a recent closely contested lawsuit, Apex sued Bpex for patent infringement. The jury came back today with its decision. The rate of return on Apex was rA = 3.1%. The rate of return on Bpex was only rB = 2.5%. The market today responded to very encouraging news about the unemployment rate, and rM = 3%. The historical relationship between returns on these stocks and the market portfolio has been estimated from index model regressions as:Apex: rA = .2% + 1.4rM Bpex: rB = −.1% + .6rMOn the basis of these data, which company do you think won the lawsuit?arrow_forwardYou believe you have found a trading strategy that could make significant profits.
