Chapter 2: Question 8-12I (page 259)

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? 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.

Short Answer

Expert verified

The correct answer is ‘c’.

Step by step solution

01

Definition

A direct implication of the Efficient Market Hypothesis is that consistently beating the market on a risk adjusted basis would be less likely as market prices should react only to the new information.

Most popular questions from this chapter

An analyst estimates that a stock has the following probabilities of return depending on the state of the economy. What is the expected return of the stock?

In Problems 21–23 below, assume the risk-free rate is 8% and the expected rate of return on the market is 18%.

A stock has an expected return of 6%. What is its beta?

Based on current dividend yields and expected capital gains, the expected rates of return on portfolios A and B are 11% and 14%, respectively. The beta of A is .8 while that of B is 1.5. The T-bill rate is currently 6%, while the expected rate of return of the S&P 500 Index is 12%. The standard deviation of portfolio A is 10% annually, while that of B is 31%, and that of the index is 20%.

a. If you currently hold a market-index portfolio, would you choose to add either of these portfolios to your holdings? Explain.

b. If instead you could invest only in bills and one of these portfolios, which would you choose?

Question: The stock of Business Adventures sells for $40 a share. Its likely dividend payout and end-of-year price depend on the state of the economy by the end of the year as follows:

a. Calculate the expected holding-period return and standard deviation of the holding period return. All three scenarios are equally likely.

b. Calculate the expected return and standard deviation of a portfolio invested half in Business Adventures and half in Treasury bills. The return on bills is 4%.

Suppose two factors are identified for the U.S. economy: the growth rate of industrial production, IP, and the inflation rate, IR. IP is expected to be 4% and IR 6%. A stock with a beta of 1 on IP and .4 on IR currently is expected to provide a rate of return of 14%. If industrial production actually grows by 5%, while the inflation rate turns out to be 7%, what is your best guess for the rate of return on the stock?
