Compute the average monthly return and monthly standard return deviation for each portfolio and all three risk factors. Also state these values on an annualized basis. (Hint: Monthly returns can be annualized by multiplying them by 12, while monthly standard deviations can be annualized by multiplying them by the square root of 12.)

Based on the return and standard deviation calculations for the two portfolios from Part a, is it clear whether one portfolio outperformed the other over this time period? Do not make any additional calculations to answer this question. Portfolio A earned a -Select- return and a -Select- standard deviation than Portfolio B. Therefore, it -Select- clear that one portfolio outperformed the other over this time period. c. Calculate the correlation coefficients between each pair of the common risk factors (i.e., 1 & 2, 1 & 3, and 2 & 3). Use a minus sign to enter negative values, if any.
