Standard VI(B), Priority of Transactions, applies. If an analyst decides to make a recommendation about the purchase or sale of a security, he must give his customers or employer adequate opportunity to act on this recommendation before acting on his own behalf. Personal transactions include those made for the member's own account and family accounts. Here, McKinney violated Standard VI(B) by acting on his mother-in-law's behalf and then waiting until the end of the day to act on his employer's behalf. 

Explanations for other responses:

• Standard IV(A), Loyalty to Employer, does not apply. This standard concerns a member competing with his/her employer (independent practice), for example a member who engages in outside consulting.
• Standard II(A), Material Nonpublic Information, does not apply. The question does not indicate that the information is not public.
