When they ask you to FORMULATE the return objective, CFAI wants to see something like this:
“John Doe’s return objective is to earn a total rate of return that is sufficient to maintain the real value of the portfolio, while meeting his daughter’s educational expenses and his living expenses.”
Don’t include numbers in the objective because if you messed them up, you will probably lose even more points.
Whatever cash flows the portfolio provides needs to be addressed in the objective. Be sure to emphasize a total rate of return and maintaining the real value of the portfolio unless specific details in the case say otherwise.
Look at previous years’ exams and see how they formulated the objective and then use the same format. I think people tend to overanalyze what the return objective should say. The return objective addresses what the portfolio is supposed to be used for, not the return requirement itself.
