Portfolio A earned a is clear that one portfolio outperformed the other over this time period. is not 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. Do not round intermediate calculations. Round your answers to four decimal places. Correlation between 1 \& 2: Correlation between 1&3 : Correlation between 2 \& 3 : d. In theory, what should be the value of the correlation coefficient between the common risk factors? Explain why. In theory the correlations should be because we want the factors to be equal to 0 independent of each other equal to 1 equal to 1 highly correlated indefinite
