What is the requirement regarding the discretionary authority in managed accounts?

A managed account gives a properly authorized portfolio manager discretionary authority to make investment decisions without obtaining client approval for each trade. Because this authority is broad, it must be clearly documented and tied to the client’s investment policy, objectives, risk tolerance, time horizon, and constraints. The trading authorization must specify the client’s investment objectives so the manager’s discretion remains controlled and suitable. Option A describes approval-based trading, not true discretion. Option B is wrong because discretionary authority cannot rely on verbal acceptance; proper written authorization and acceptance are required. Option C is incorrect because managed accounts are not defined by model portfolios or short-term use. The key requirement is documented authority aligned with the client’s objectives.
