| GJCFA | Beta of market portfolio is 1. If Q has SD more than that of market portfolio, then it's beta has to be more than 1. Only option available is A. No calculation needed! |
| moneyguy | I'm sure we'll be seeing some of these on the exam. |
| johntan1979 | GJCFA, your assumption is wrong. In this case, the correlation coefficient, p is 1.30 = p x 0.40 / 0.24 p = 0.78 If p is 0.462, then beta is 0.77 (less than one) Don't simply assume. Know the formula and calculate it. |
| khalifa92 | or: (0.075/(0.24*0.4))*(0.4/0.24)=1.3021 |
I am happy to say that I passed! Your study notes certainly helped prepare me for what was the most difficult exam I had ever taken.
