Introduction:
EMH which is known as efficient market hypothesis stand to be the investment theory wherein price of a share represent the entire information, however consistent alpha generation stands to be impossible.

- 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?arrow_forward7. Which of the following would provide evidence against the semi-strong form of the efficient market theory? About 50% of pension funds outperforms the market in any year. All investors have learned to exploit signals about future performance. Trend analysis is worthless in determining stock prices. Low P/E stocks tend to have positive abnormal returns over the long run.arrow_forwardSuppose 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.arrow_forward

You complete a test of autocorrelation on daily data for a thinly traded stock and the Durbin Watson statistic is 1.15. If the stock has a return of -0.33% late in the trading day and you are convinced that other investors are not aware of the results, based on the test results and probabilities, an investor would: Buy or long the stock in late trading. Sell or short the stock in late trading. Wait an additional day to buy the stock. Wait an additional day to short the stock. Take neither a long or short position in the stock. None of the above answers is correct.arrow_forwardStock A is expected to return 14 percent in a normal economy and lose 21 percent in a recession. Stock B is expected to return 11 percent in a normal economy and 5 percent in a recession. The probability of the economy being normal is 75 percent with a 25 percent probability of a recession. What is the covariance of these two securities? A) .007006 B) .005180 C) .006274 D) .003938 (Don't Hand writing in solution) .arrow_forward

A hedge fund manager believes that Waterworks is underpriced, with an alpha of 2% over the coming month. Beta 0.75 R-square 0.65 Now suppose that the manager misestimates the beta of Waterworks stock, believing it to be 0.50 instead of 0.75. The standard deviation of the monthly market rate of return is 5%. Standard Deviation of Residuals 0.06 (i.e., 6% monthly) Required: a.
