Select any type of company (e.g., your employer or the company for your current event paper or weekly stock research project) and set up the equation for calculating the required or expected rate of return using the APT model. Use your own estimates for the weighting of each factor, so that the equation accurately generates a required or expected rate of return that is mathematically correct. [Helpful hint: do not spend too much time or "overthink" this problem as this merely a hypothetical exercise to measure your comprehension on how the APT model can be applied in real world situations.] ALSO you are not called upon to calculate an E(r) but to set up the equation with the appropriate weighting factors only.
