Jerry Mack, CFA, an investment advisor, leaves his employer (Firm 1) to start at a competing firm (Firm 2). Mack does not have a noncompete agreement with Firm 1. Before leaving Firm 1, he calls his long-term client to describe Firm 2's product offerings so he can help the client reach his financial goals. After joining Firm 2, he opens a new social media account. From memory, he finds all his former clients on the social media platform and solicits business from them.

Did Mack's actions violate the Standard relating to loyalty?
