Most academics use three to five factors to model returns, but the factors selected have not been empirically robust. A factor beta aka factor sensitivity, factor loading can also be calculated for each type of macroeconomic factor risk, equal to the percentage change in the expected return for each unit change in the macroeconomic risk factor.
