Series 6 Suitability: How to Answer Customer Profile Questions
Suitability questions are the most common Series 6 exam scenario. Learn the customer profile factors, Reg BI obligations, and how to apply them to practice questions.
June 12, 2025
Suitability scenarios make up a significant portion of Series 6 exam questions, and they are also among the most misunderstood. Candidates who approach them as product-knowledge questions tend to struggle. The correct approach is to read the customer profile first and match the recommendation to the investor's specific situation — not to identify the "best" product in the abstract.
Regulation Best Interest: The Current Standard
The SEC's Regulation Best Interest (Reg BI), which became effective June 30, 2020, replaced the older suitability standard for broker-dealer recommendations to retail customers. This is what the Series 6 tests.
Under Reg BI, a broker-dealer and its registered representatives must act in the best interest of a retail customer when making a recommendation. Reg BI has four component obligations:
-
Disclosure Obligation: Before or at the time of a recommendation, provide the retail customer with a written disclosure (Form CRS — Customer Relationship Summary) covering the nature of the relationship, fees, conflicts of interest, and whether the firm provides investment advisory or brokerage services.
-
Care Obligation: Exercise reasonable diligence, care, and skill to understand the potential risks, rewards, and costs of a recommended product. Have a reasonable basis to believe the recommendation is in the customer's best interest given their investment profile.
-
Conflict of Interest Obligation: Establish written policies to identify, disclose, and mitigate or eliminate conflicts. Financial incentives to recommend one product over another must be addressed.
-
Compliance Obligation: Maintain written policies and procedures reasonably designed to comply with Reg BI.
The key distinction between Reg BI and the old FINRA suitability rule: Reg BI prohibits placing the financial interest of the firm or representative ahead of the retail customer's interest. It is a higher standard than mere suitability.
New Account Form Requirements
Before a representative can make a suitability-based recommendation, the firm must collect information about the customer. The new account form captures this profile. FINRA rules require firms to make reasonable efforts to obtain the following information before or at the time of the first transaction:
- Investment objectives (capital preservation, income, growth, speculation)
- Financial situation and needs (income, assets, liabilities, net worth)
- Tax status
- Risk tolerance (conservative, moderate, aggressive)
- Time horizon (short-term, medium-term, long-term)
- Liquidity needs
- Other investments held (to assess concentration)
- Age (particularly relevant for senior investor considerations)
If a customer declines to provide information, the representative may still open the account and execute unsolicited transactions, but cannot make recommendations without the necessary profile data.
Matching Products to Investor Profiles
Conservative investor, short time horizon, high liquidity need
This profile calls for capital preservation and low volatility. Money market funds, short-term bond funds, or fixed annuities (if insurance-licensed) fit here. Equity mutual funds, variable annuities, and variable life insurance are not appropriate — the time horizon is insufficient to recover from market losses.
Moderate investor, 10-15 year time horizon, retirement focused
A balanced mutual fund (blending equities and fixed income) or a target-date fund aligns with this profile. Variable annuities could be appropriate if tax deferral is a priority and the investor has already maximized qualified plan contributions.
Aggressive investor, long time horizon, high risk tolerance
Growth equity funds or sector funds may be appropriate. However, if the investor already has heavy stock concentration, adding more equity exposure may create unacceptable concentration risk.
Near-retirement or retired investor
Income-generating investments — bond funds, dividend-focused equity funds — are typically more appropriate than growth-oriented products. Variable life insurance is generally unsuitable when the time horizon is short and premium sustainability is uncertain.
Concentration Risk
The Series 6 tests concentration risk in suitability scenarios. If a customer already holds a large percentage of their portfolio in a single sector, issuer, or asset class, recommending more of the same creates concentration risk even if the individual product is otherwise suitable. A recommendation is only suitable when viewed in the context of the customer's entire financial situation.
Senior Investor Considerations
FINRA and state regulators have added explicit protections for older investors:
-
Trusted Contact Person: FINRA Rule 4512 requires broker-dealers to make reasonable efforts to obtain the name of a trusted contact person for all non-institutional customers. This person can be contacted if there is concern about financial exploitation or the customer's health.
-
Financial exploitation: Representatives who suspect financial exploitation of a senior or vulnerable adult may — and in many states must — place a temporary hold on disbursements while the firm investigates. FINRA Rule 2165 provides a safe harbor for such holds.
-
Suitability re-evaluation: As investors age, risk tolerance, time horizon, and income needs often change materially. Representatives have an ongoing obligation to update customer profiles and re-evaluate whether existing holdings remain appropriate.
Answering Suitability Questions on the Exam
When you encounter a suitability scenario, use this process:
- Identify the customer's stated investment objective and time horizon.
- Note any special circumstances: fixed income need, tax bracket, existing assets, age.
- Eliminate answer choices that clearly mismatch (e.g., a speculative fund for a capital preservation objective).
- Among remaining choices, select the one that best fits all the profile factors, not just the most prominent one.
- If a question asks about a prohibited recommendation, look for conflicts of interest, concentration problems, or unsuitability based on time horizon.
Suitability and Reg BI scenarios are tested in almost every Series 6 exam. Advisor Exam Academy's question bank includes dozens of customer profile scenarios with step-by-step explanations of why each answer choice is right or wrong. Start your Series 6 prep at advisorexams.com/exams/series-6.
