- The following is part of the computer output from a regression of monthly returns on Waterworks stock against the S&P 500 Index. 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. If he holds a $6 million portfolio of Waterworks stock and wishes to hedge market exposure for the next month using one-month maturity S&P 500 futures contracts, what is the standard deviation of the (now improperly) hedged portfolio?

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.

- In relation to the efficient markets hypothesis, consider the following observations: Mutual fund managers do not on average make superior returns. In any year approximately 50 percent of all pension funds outperform the market. It is possible to make superior returns by buying or selling stocks after the announcement of an abnormal rise in earnings. Managers who trade in their own stocks make superior returns. Which of the following statements is true? I does not provide evidence against semi-strongform efficiency, but II does provide evidence against semi-strong form efficiency. II does not provide evidence against semi-strongform efficiency, but I does provide evidence against semi-strong form efficiency. Both I and II provide evidence against the semi-strongform of market efficiency III provides evidence against semi-strong form efficiency and IV provides evidence against strongform efficiency. III and IV provide evidence against semi-strong form efficiency.arrow_forwardThe following is part of the computer output from a regression of monthly returns on Waterworks stock against the S&P 500 index.
