Suitability is a regulatory standard that requires broker-dealers and their registered representatives to have a reasonable basis to believe that a recommended security or investment strategy is suitable for the particular customer at the time of the recommendation.
Three suitability obligations (FINRA Rule 2111):
1. Reasonable-basis suitability: The broker must understand the product and have a reasonable basis to believe it could be suitable for at least some investors. 2. Customer-specific suitability: The recommendation must be suitable for the specific customer based on that customer's investment profile. 3. Quantitative suitability: The broker must not recommend excessive trading (churning) even if each individual trade was suitable.
Customer investment profile includes: - Age and time horizon. - Risk tolerance. - Financial situation and needs (income, net worth, liquidity needs). - Investment objectives. - Tax status. - Other investments (portfolio context).
Suitability vs. Reg BI vs. Fiduciary:
| Standard | Applies to | Key difference | |---|---|---| | Suitability | BD recommendations (pre-Reg BI framework) | Meet a reasonable appropriateness threshold | | Reg BI | BD recommendations to retail clients | Must act in client's best interest, not just suitable | | Fiduciary | Investment advisers (RIAs) | Ongoing duty of loyalty and care |
Suitability is transactional: It applies at the time of each recommendation — not an ongoing duty.
> Exam tip: Suitability applies to broker-dealers; the fiduciary standard applies to investment advisers. Reg BI (2020) effectively elevated the B/D standard above simple suitability but below a full fiduciary duty. Know all three standards for the SIE, Series 7, and Series 65/66.
