A stock market analyst is able to identify mispriced stocks by comparing the average price for the last 10 days to the average price for the last 60 days. If this is true, what do you know about the market?
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.
An index model regression applied to past monthly returns in Ford’s stock price produces the following estimates, which are believed to be stable over time: rF = 0.1% + 1.1rM If the market index subsequently rises by 7.3% and Ford’s stock price rises by 7%, what is the abnormal change in Ford’s stock price? (Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.).

- Market 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_forwardA. If a stock costs $55 one month and drops to $45 the next month, what is the expected stock price the next month, if we assume the stock follows a random walk? B.

- An index model regression applied to past monthly returns in Ford’s stock price produces the following estimates, which are believed to be stable over time:rF = .10% + 1.1rMIf the market index subsequently rises by 8% and Ford’s stock price rises by 7%, what is the abnormal change in Ford’s stock price?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_forwardTwo stock prices for six days are given below.
