A money manager and member of CFA Institute is meeting with a prospect. She gives the client a list of stocks and says, "These are the winners I picked this past year for my clients. Their double-digit returns indicate the type of returns I can earn for you." The list includes stocks the manager had picked for her clients, and each stock has listed with it an accurately measured return that exceeds 10 percent. Is this a violation of Standard Ⅲ (D), Performance Presentation()

A. Yes, because the manager cannot reveal historical returns of recent stock picks.

B. No, because the manager had the historical information in writing.

C. Yes, unless the positions listed constitute a complete presentation (i. e. there were no stocks omitted that did not perform in the double digits).
