## What it does

The skill evaluates securities and strategies across all three prongs of FINRA Rule 2111: reasonable-basis, customer-specific, and quantitative suitability. It ties directly into FINRA Rule 2090 (Know Your Customer) by factoring in age, liquid net worth, investment horizon, tax status, and loss capacity. Refusals to supply profile data get flagged, narrowing the scope of compliant recommendations.

Dedicated checks cover complex instruments. The skill accounts for the daily reset mechanism in leveraged and inverse ETFs, treating them as unsuited for buy-and-hold strategies. It evaluates variable annuities under Rule 2330, reviewing surrender fees across 5-8 years alongside tax redundancy in retirement accounts. For trading volume, turnover ratios above 6 or cost-to-equity ratios above 20% trigger unsuitability warnings.

For investigating churning or enforcement matters around excessive trading, this skill does not apply; its author directs those inquiries to sales-practices.

description: "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.)"

# Investment Suitability

Regulatory status current as of June 2026 — verify effective dates, dollar thresholds, and pending rulemakings against current SEC/FINRA/FinCEN sources before advising.

## Core Concepts

### FINRA Rule 2111 — Suitability
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:

### Three Suitability Obligations

**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))**
```
