William Wong, CFA, is an equity analyst with Hayswick Securities. Based on his fundamental analysis, Wong concludes that the stock of a company he follows, Nolvec Inc., is substantially undervalued and will experience a large price increase. He delays revising his recommendation on the stock from "bold" to "buy" to allow his professional conduct that relate to:（）
A. Duty to clients.
B. Reasonable basis.
C. Duty to his employer.
参考答案：B
解析：
There is nothing to suggest that Wong does not have a reasonable basis for his conclusion related to Nolvec. However, by delaying the revision of his recommendation so that his brother can buy shares at a lower price, he has Violated the CFA Institute Standards relating to duty to client, duty to employer, and priority of transactions.
