joellewis/investment-suitability
Assess investment suitability obligations under FINRA Rules 2111 and 2090 across all three suitability prongs. Use when the user asks about reasonable-basis, customer-specific, or quantitative suitability, product-specific concerns for complex products, leveraged ETFs, variable annuities, or alternatives, household-level suitability and concentration analysis, hold recommendations, or the institutional suitability exemption. Also trigger when users mention 'is this investment suitable', 'suitability questionnaire design', 'complex product due diligence', 'concentrated position in a client account', 'customer refused to provide their risk tolerance', or ask whether a recommendation fits a customer's profile. (For churning, turnover-ratio, and excessive-trading enforcement triggers, use sales-practices.)

The foundational rule requiring that a broker-dealer or associated person have a reasonable basis for believing a recommendation is suitable for the customer. Applies to recommendations of securities and investment strategies involving securities, including recommendations to hold. Three distinct obligations arise from Rule 2111:
1. Reasonable-Basis Suitability (Rule 2111.05(a))
The firm or associated person must perform reasonable diligence to understand the nature of the recommended security or strategy, including its risks, rewards, and features. This is a product-level obligation — the representative must understand what they are recommending before recommending it to anyone. A representative who does not understand a complex product cannot satisfy reasonable-basis suitability regardless of how well it might fit a particular customer.
2. Customer-Specific Suitability (Rule 2111.05(b))
The recommendation must be suitable for the particular customer based on that customer's investment profile. The investment profile includes, but is not limited to: age, other investments, financial situation and needs, tax status, investment objectives, investment experience, investment time horizon, liquidity needs, risk tolerance, and any other information the customer discloses.
3. Quantitative Suitability (Rule 2111.05(c))
The firm or associated person must have a reasonable basis for believing that a series of recommended transactions, even if each is individually suitable, is not excessive and unsuitable when taken together in light of the customer's investment profile. The former requirement that the broker have "actual or de facto control" over the account was removed by FINRA's 2020 amendments to Rule 2111 (Regulatory Notice 20-18; SR-FINRA-2020-007, effective June 30, 2020), aligning the obligation with Reg BI's Care Obligation — quantitative suitability now turns on the recommendations alone, without any control element. Key metrics: turnover ratio (annualized), cost-to-equity ratio, and use of in-and-out trading patterns. Generally, turnover ratios above 6 and cost-to-equity ratios above 20% raise presumptive concerns.
Requires every member to use reasonable diligence to know and retain the essential facts concerning every customer and the authority of each person acting on the customer's behalf. This is the foundation that feeds suitability analysis — you cannot assess suitability without first knowing the customer. Essential facts include identity, financial status, investment objectives, and the nature and type of account.
The customer investment profile under Rule 2111 includes:
A customer may decline to provide profile information, but the firm must document the refusal and recognize that the more information withheld, the narrower the range of suitable recommendations.
Complex Products: FINRA Regulatory Notice 12-03 provides heightened suitability guidance for complex products (structured products, leveraged/inverse ETFs, hedge funds, non-traded REITs). Firms must perform heightened reasonable-basis diligence, develop targeted training, and consider whether enhanced customer-specific suitability review is needed.
Leveraged and Inverse ETFs: These products reset daily, meaning their performance over periods longer than one day can deviate significantly from the leveraged/inverse benchmark return. FINRA has flagged that these are generally unsuitable for buy-and-hold investors. Suitability analysis must account for the daily reset mechanism and its compounding effects.
Variable Annuities: Subject to FINRA Rule 2330, which imposes heightened suitability requirements. Before recommending a VA, the representative must consider: liquidity needs (surrender charges typically 5-8 years), tax status (tax-deferred growth is redundant in an IRA), subaccount investment options, rider costs and benefits, and whether a 1035 exchange is in the customer's interest.
Options: FINRA Rule 2360 requires account-level approval before options trading, with suitability assessed across strategy tiers (covered writing, spreads, uncovered writing, etc.). The Options Disclosure Document (ODD) must be delivered before account approval.
Alternative Investments: Private placements, hedge funds, and non-traded products present heightened suitability concerns due to illiquidity, complexity, high fees, and limited transparency. FINRA expects enhanced due diligence on the product issuer and heightened customer-specific suitability review.
Suitability is assessed at the customer level, not the account level, but household context matters. A concentrated position in one account may be suitable if diversified across the household. However, firms must have a reasonable basis for knowing the household context — relying on assumptions about held-away assets without verification creates risk. FINRA expects firms to consider a customer's overall financial picture to the extent it is known or reasonably discoverable.
Since the 2012 adoption of Rule 2111 (which extended suitability to recommended "investment strategies involving securities," including explicit recommendations to hold), a hold recommendation is subject to suitability obligations. This closed a longstanding gap under predecessor NASD Rule 2310, where representatives could avoid suitability review by recommending inaction. A hold recommendation on a concentrated or illiquid position must be evaluated against the customer's current profile.
The customer-specific suitability obligation may be modified for institutional accounts (as defined in FINRA Rule 4512(c)) if: (1) the firm has a reasonable basis to believe the institutional customer is capable of evaluating investment risks independently, and (2) the institutional customer affirmatively indicates it is exercising independent judgment. Both conditions must be met — the exemption is not automatic for all institutional clients.
Since June 30, 2020, broker-dealer recommendations to retail customers are governed by Regulation Best Interest (Reg BI), which imposes a higher standard than FINRA suitability. Reg BI's Care Obligation requires consideration of reasonably available alternatives and a cost-benefit analysis — obligations that go beyond traditional suitability. FINRA suitability remains relevant for institutional clients and as a component of the Reg BI framework. See the reg-bi skill for full Reg BI coverage.
FINRA disciplinary actions frequently target:
Scenario: A registered representative recommends that a 72-year-old retired client invest 60% of her $500,000 IRA in a single technology stock. The client's investment objective is listed as "income" with a "moderate" risk tolerance. She relies on the account for living expenses.
Compliance Issues: Customer-specific suitability violation. The recommendation creates concentration risk inconsistent with income objectives, moderate risk tolerance, short time horizon (income-dependent), and high liquidity needs. Age is a significant factor — the client has limited ability to recover from a loss.
Analysis: The representative should have recommended a diversified income-oriented portfolio consistent with the stated objectives. Even if the client expressed enthusiasm for the stock, the representative has an independent obligation to assess suitability and document the rationale. FINRA would likely view this as a customer-specific suitability violation and potentially a supervision failure if the firm lacked exception reporting for concentration.
Scenario: A representative recommends a leveraged inverse ETF to a moderate-risk client as a "hedge" against market declines, suggesting the client hold it for six months. The representative cannot explain the daily reset mechanism or the compounding effects over multi-day holding periods.
Compliance Issues: Reasonable-basis suitability violation. The representative does not understand the product's key feature (daily reset) and is recommending a holding period inconsistent with the product's design. Additionally, customer-specific suitability is questionable for a moderate-risk investor.
Analysis: FINRA Regulatory Notice 09-31 specifically warns that leveraged/inverse ETFs that reset daily are typically unsuitable for retail investors who plan to hold them longer than one trading session. The representative's inability to explain the reset mechanism is a clear reasonable-basis failure. The firm should have product-specific training requirements and suitability guardrails for leveraged ETF recommendations.
Scenario: A representative with discretionary authority over a client's $200,000 account executes 150 trades over 12 months, generating $46,000 in commissions. The account's annualized turnover ratio is 8.2 and the cost-to-equity ratio is 23%. The client's objective is "growth" with a "moderate-to-aggressive" risk tolerance.
Compliance Issues: Quantitative suitability violation. The turnover ratio (8.2 > 6 threshold) and cost-to-equity ratio (23% > 20% threshold) both exceed presumptive thresholds for excessive trading. Since the 2020 amendments, no showing of control is required under Rule 2111.05(c) — the recommended (here, discretionary) transactions alone are evaluated.
Analysis: Even though individual trades may have been suitable, the pattern of trading is excessive in the aggregate. The account must generate returns exceeding 23% just to break even after costs — an unreasonable hurdle. FINRA would examine the excessive activity itself (quantitative metrics); control and scienter remain relevant only if regulators also pursue fraud-based churning charges under Rule 10b-5. The firm's supervision system should have flagged this through exception reporting on turnover and cost-to-equity ratios.
