Worked Practitioner Scenario

Practitioner Application: Unethical Business Practices for Investment Advisers: Navigating Fiduciary Duties

Imagine you're an IAR. A client, eager for high returns, asks you to guarantee a specific profit on their portfolio. Another client, a close friend, wants you to manage their personal funds alongside your firm's client accounts to save on fees. Both scenarios present immediate ethical and legal red flags. The Series 65 exam frequently tests your ability to identify and respond to such situations, distinguishing between permissible actions with disclosure and outright prohibited conduct. Understanding the specific rules and the underlying fiduciary duty is paramount to passing this section.

  1. Investment Advisers (IAs) and their representatives (IARs) operate under a stringent fiduciary duty to their clients. This means they must always act in the client's best interest, placing client interests ahead of their own. The Uniform Securities Act and the NASAA Model Rules define specific practices that violate this duty, leading to disciplinary action. While Regulation Best Interest (Reg BI) imposes a best interest standard on broker-dealers when recommending securities to retail customers, the specific list of unethical practices for IAs and IARs, and their overarching fiduciary standard, is primarily guided by the Investment Advisers Act of 1940 and the NASAA Model Rules.
  2. 1. Charging Unreasonable Fees (NASAA Model Rule 102(a)(4)-1(A)(4)): Fees must be reasonable in relation to the services provided. Factors considered include the type of service, complexity, time required, and the adviser's expertise. Excessive markups/markdowns on principal transactions are also prohibited.
2. Guarantees (NASAA Model Rule 102(a)(4)-1(A)(1)): IAs/IARs are strictly prohibited from guaranteeing clients specific returns or protection from loss. Investment involves risk, and such guarantees are inherently misleading.
