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? The average rate of return is significantly greater than zero. The correlation between the return during a given week and the return during the following week is zero. One could have made superior returns by buying stock after a 10% rise in price and selling after a 10% fall. One could have made higher-than-average capital gains by holding stocks with low dividend yields.

Which of the following statements is CORRECT? Suppose the returns on two stocks are negatively correlated. One has a beta of 1.2 as determined in a regression analysis using data for the last 5 years, while the other has a beta of −0.6. The returns on the stock with the negative beta must have been negatively correlated with returns on most other stocks during that 5-year period. Suppose you are managing a stock portfolio, and you have information that leads you to believe the stock market is likely to be very strong in the immediate future. That is, you are convinced that the market is about to rise sharply. You should sell your high-beta stocks and buy low-beta stocks in order to take advantage of the expected market move. You think that investor sentiment is about to change, and investors are about to become more risk averse. This suggests that you should re-balance your portfolio to include more high-beta stocks. If the market risk premium remains constant, but the risk-free rate…

You've estimated the following expected returns for a stock, depending on the strength of the economy: State (s) Probability Expected return Recession 0.1 -0.05 Normal 0.5 0.06 Expansion 0.4 0.11 What is the expected return for the stock? What is the standard deviation of returns for the stock?

Suppose you estimate that the correlation between Abercrombie and Fitch (ANF) stock returns with market portfolio returns is 0.85.  You also estimate that ANF's stock return's are twice as variable (σANFσM=2.0).   Therefore, what is the the beta for ANF stock (βANF) ?

Blue Bell stock is expected to return 8.4 percent in a boom, 8.9 percent in a normal economy, and 9.2 percent in a recession. The probabilities of a boom, normal economy, and a recession are 6 percent, 92 percent, and 2 percent respectively. What is the standard deviation of the returns on this stock? Can the calculator an excel solution be provided?

An antitrust case has lead to you having to calculate a fair return (using the CAPM) for RadioEthiopea common stock. The market has a volatility of 18.00%, while the shares have a volatility of 33.00%. The correlation between the two sets of returns is -0.10. The risk free rate is 1.90%, while the expected return on the market is 4.30%. What is the fair return for RadioEthiopea common stock?     1.11%     1.77%     1.46%     1.66%
