A marketing piece claiming FINRA “endorses” a broker-dealer is not permissible, so A is correct. FINRA is a self-regulatory organization that oversees broker-dealers; it does not “endorse” member firms as a marketing claim. Communications with the public must be fair and not misleading. Suggesting FINRA endorsement could mislead customers into thinking the regulator has approved the firm’s quality, products, or services, which conflicts with the disclosure-based framework and the principle that regulators do not provide merit-based approval of market participants.

Choice B is incorrect because principal approval does not make a misleading statement permissible. Principal approval is an internal supervisory step; it cannot legalize a false or misleading representation. Choice C is incorrect because FINRA does not provide written approvals to allow firms to claim endorsement; the concept itself is improper. Choice D is incorrect because the issue is not whether specific investments are mentioned; the misrepresentation is the claim of regulatory endorsement, which is misleading regardless of content.

SIE exam questions in this area test your ability to spot prohibited or misleading marketing language—especially anything implying government or regulator “approval,” “guarantee,” or “endorsement.” Similar logic applies to claims that the SEC approves a prospectus or the merits of an offering. The correct approach in communications is accurate, balanced disclosure—not implying that a regulator supports or recommends the firm.
