单选题 Michael Allen, CFA, works for an investment management company and manages portfolios for a variety of retail and institutional clients for his firm, including his wealthy uncle, all of whom pay a management fee for his services. Lawrence Brown, an analyst at a brokerage firm has recommended Allen a high yield hedge fund based on its historical performance. Allen purchases a large block of this hedge fund and allocates proportionately to all client portfolios, including his uncle's portfolio. Has Allen most likely violated the Standards of Professional Conduct?
A. No.
B. Yes, relating to suitability.
C. Yes, relating to fair dealing.

【正确答案】 B
【答案解析】[解析] 因为Allen的叔叔也是他的客户,所以Allen需要公平地对待所有客户,包括他的叔叔。题目中,按比例(proportionately)分配并没有违反公平对待的行为标准。但是,不根据客户的投资目标和限制而盲目给所有的客户进行购买,违反了合适性原则。
