Worked Practitioner Scenario

Practitioner Application: Ethical Conduct, Prohibited Activities, and Regulatory Enforcement

A registered representative receives a fantastic 'tip' from a close friend, who happens to be a senior executive at a publicly traded company, about an imminent merger announcement that will significantly boost the stock price. The representative also has a passion for building custom furniture and wants to start selling pieces online for extra income. How should the representative handle the 'tip,' and what are their obligations to their firm regarding the furniture business? Navigating these situations ethically and compliantly is paramount in the securities industry.

  1. FINRA's Conduct Rules are designed to ensure that registered representatives and member firms act with integrity, honesty, and in the best interest of their clients and the markets. These rules underpin the ethical framework of the securities industry.
  2. FINRA Rule 2010 (Standards of Commercial Honor and Principles of Trade): This is a broad, overarching rule requiring member firms and associated persons to 'observe high standards of commercial honor and just and equitable principles of trade.' It acts as a catch-all for unethical conduct not specifically covered by other rules.
FINRA Rule 2111 (Suitability): This rule requires firms and registered representatives to have a reasonable basis to believe that a recommended transaction or investment strategy is suitable for the customer. Suitability has three main components: 1. Reasonable-basis suitability: The recommendation must be suitable for at least some investors (i.e., the product itself must be legitimate and understood by the representative). 2. Customer-specific suitability: The recommendation must be suitable for the specific customer* based on their investment profile (age, financial situation, investment objectives, risk tolerance, time horizon, etc.). 3. Quantitative suitability: A series of recommended transactions, even if individually suitable, must not be excessive or inappropriate when viewed in relation to the customer's investment profile (e.g., excessive trading or 'churning').
