Suppose that the index model for stocks A and B is estimated from excess returns with the following results:RA = 3% + .7RM + eARB = −2% + 1.2RM + eBσM = 20%; R-squareA = .20;                    R-squareB = .12What are the covariance and the correlation coefficient between the two stocks?
(Expected rate of return and risk) Syntex, Inc. is considering an investment in one of two common stocks. Given the information that follows, which investment is better, based on the risk (as measured by the standard deviation) and return? Common Stock A Probability 0.20 0.60 0.20 Probability 0.15 0.35 0.35 0.15 (Click on the icon in order to copy its contents into a spreadsheet.) ew an example Get more help. T 3 a.

Using an example of two stocks (e.g., A and B) with hypothetical known values for the mean return and standard deviation (you should provide the numerical values), discuss how the Coefficient of Variation can be used to compare the relative risks of the two stocks. If the risk- free return is 1%, what are the Sharpe Ratios for the two stocks? How do you compare the returns of the two stocks using the Sharpe Ratios? What are the potential limitations of comparing risks and returns in this way?
