When to Use This Prompt

Define the exact job, the user, and the hard boundaries for deploying an investment recommendation refusal prompt in a production AI system.

This prompt is designed for a single, high-stakes job: refusing to provide personalized investment recommendations, portfolio allocation advice, or market timing suggestions in a retail investing or brokerage AI interface. The ideal user is a product engineer or compliance architect embedding an AI copilot into a consumer-facing fintech application. The prompt must be used when the system is subject to regulatory oversight (e.g., SEC, FINRA) and where an unqualified recommendation creates real legal liability, not just brand risk. The required context includes the user's raw query, the system's registered capacity (e.g., educational, execution-only), and any relevant disclaimers already shown in the session.

Do not use this prompt when the user is asking for purely factual security descriptions, historical performance data, or educational content about financial concepts. The prompt is not a general financial disclaimer; it is a targeted refusal for recommendation-like requests. If you apply it to benign requests for definitions or public filings, you will create over-refusal and degrade the user experience. The prompt also assumes the model has no access to the user's personal financial situation, goals, or risk tolerance. If your application does have that data, you must add explicit guardrails that prevent the model from synthesizing a recommendation even when it has the inputs.

Before deploying this prompt, you must define what constitutes a recommendation in your jurisdiction and product context. Work with product counsel to create a concrete taxonomy of prohibited output types: buy/sell/hold statements, portfolio percentage allocations, market timing suggestions, and suitability implications. The prompt template includes placeholder variables for these definitions so you can adapt it to your specific policy. After deployment, monitor for two common failure modes: the model providing an implied recommendation through framing (e.g., 'many investors are buying this right now') and the model refusing a clearly educational request because it contains a ticker symbol. Both require eval checks and likely prompt tuning.

PRACTICAL GUARDRAILS

Use Case Fit

Where the Investment Recommendation Refusal Prompt works, where it breaks, and what you must provide before deploying it into a retail brokerage or fintech AI surface.

01

Good Fit: Retail Self-Directed Platforms

Use when: the AI sits inside a brokerage app, retirement portal, or personal finance tool used by retail investors who may ask 'should I buy X?' or 'is now a good time to sell?' Guardrail: the prompt must refuse personalized buy/sell/hold recommendations while still answering factual questions about security fundamentals, expense ratios, or historical volatility.

02

Bad Fit: Advisor-Augmentation Workflows

Avoid when: the AI is designed to assist registered investment advisors (RIAs) or licensed brokers who need to generate draft recommendations for review. Risk: a refusal prompt in this context blocks the core workflow and frustrates professionals who understand their own compliance obligations. Guardrail: use a disclaimer-plus-drafting prompt with human-review gates instead of a hard refusal.

03

Required Input: Clear Policy Boundaries

What to watch: without explicit definitions of what constitutes a 'recommendation,' the model will either over-refuse on benign educational content or under-refuse on implied advice. Guardrail: provide a concrete policy document that defines recommendation vs. education, with examples of permitted and prohibited response patterns, before deploying the prompt template.

04

Required Input: Jurisdiction Awareness

What to watch: investment advice regulations differ across SEC, FCA, ESMA, and other jurisdictions. A single refusal prompt may be too permissive in one region and too restrictive in another. Guardrail: include a jurisdiction parameter that adjusts refusal strictness and disclaimer language based on the user's regulatory context.

05

Operational Risk: Suitability Implication Leakage

Risk: the model refuses to say 'buy X' but still implies suitability through language like 'X has strong fundamentals and low fees, making it popular for retirement accounts.' Guardrail: add eval tests that detect implied recommendations, not just explicit buy/sell/hold language. Run these tests in CI before every prompt update.

06

Operational Risk: Performance Prediction Drift

Risk: the model refuses direct predictions but offers forward-looking statements like 'analysts expect growth' or 'the sector is positioned for expansion.' Guardrail: include explicit instructions to avoid any forward-looking performance language, cite only historical data, and flag analyst opinions as third-party views, not model endorsements.

PROMPT PLAYBOOK

Copy-Ready Prompt Template

A reusable refusal template with square-bracket placeholders that you can adapt for your retail investing or brokerage AI interface.

This template is designed to refuse personalized buy/sell/hold recommendations, portfolio allocation advice, and market timing suggestions while still permitting factual security descriptions and educational content. It uses square-bracket placeholders so you can inject your own policy language, risk level, and output schema without rewriting the core refusal logic. The template is structured to be used as a system prompt or as a policy instruction block within a larger system prompt architecture.

text
You are an AI assistant in a retail investing context. Your role is to provide factual information and educational content about securities, markets, and financial concepts. You must refuse any request that asks for personalized investment recommendations, portfolio allocation advice, or market timing suggestions.

When you receive a user request, classify it against the following policy:

- [POLICY_DEFINITION]: A clear statement of what constitutes a disallowed recommendation. For example: "Any statement that suggests a specific action (buy, sell, hold) for a specific security based on the user's personal circumstances, goals, or risk tolerance is disallowed."
- [PERMITTED_CONTENT]: A description of what you may provide. For example: "You may provide factual descriptions of securities, historical performance data, general education about investment concepts, and explanations of regulatory filings."

If the request falls under [POLICY_DEFINITION], respond with the following refusal structure:

1. A clear, direct statement that you cannot provide personalized investment recommendations.
2. A brief explanation of why (reference [POLICY_DEFINITION] without quoting it verbatim).
3. If applicable, offer a [SAFE_ALTERNATIVE] such as factual information about the security or educational content about the relevant concept.
4. If the request involves [HIGH_RISK_DOMAIN] such as options trading, margin, or cryptocurrency, include a [RISK_DISCLAIMER] and recommend consulting a qualified financial professional.

User request: [USER_INPUT]

Respond in the following JSON format:
[OUTPUT_SCHEMA]

To adapt this template, replace each square-bracket placeholder with your organization's specific policy language, risk definitions, and output format requirements. The [POLICY_DEFINITION] should be drafted in collaboration with your compliance team to ensure it accurately reflects regulatory obligations under SEC and FINRA rules. The [SAFE_ALTERNATIVE] placeholder should be populated with a list of permitted response types that your product team has validated as useful without crossing into recommendation territory. If your application requires structured logging for audit purposes, ensure the [OUTPUT_SCHEMA] includes fields for refusal reason codes, policy citations, and timestamps. Before deploying, run this template through your regression test suite using the eval criteria described in the Testing and Evaluation section of this playbook.

IMPLEMENTATION TABLE

Prompt Variables

Required inputs for the Investment Recommendation Refusal Prompt Template. Each placeholder must be populated before the prompt is assembled and sent to the model. Validation notes describe how to verify the input is fit for purpose.

PlaceholderPurposeExampleValidation Notes

[USER_QUERY]

The raw user message that triggered the refusal evaluation

Should I buy NVDA right now or wait for a pullback?

Non-empty string required. Check for null, empty, or whitespace-only input before invoking the prompt. Log original query for audit trail.

[USER_CONTEXT]

Known facts about the user's relationship to the platform

Retail brokerage customer; self-directed account; non-professional subscriber

Must be supplied from session or account metadata. Null allowed if anonymous. If null, treat as highest-risk retail user. Validate against auth service claims.

[PLATFORM_TYPE]

The regulated service category the AI operates within

Self-directed brokerage platform

Must match an approved enum: 'Self-directed brokerage platform', 'Robo-advisor', 'Financial education portal', 'Market data terminal'. Reject unknown values.

[JURISDICTION]

The regulatory jurisdiction governing the interaction

US-SEC-FINRA

Must match an approved jurisdiction code. If unknown, default to most restrictive policy. Validate against user account country and platform registration.

[PERMITTED_CONTENT_TYPES]

Explicit list of content categories the system is allowed to produce

Security descriptions; historical performance data; educational definitions; risk disclosures

Must be a non-empty array of approved content type strings. Each type must exist in the platform's allowed-content registry. Reject prompt assembly if array is empty.

[REFUSAL_TONE]

The stylistic directive for how the refusal should sound

Professional and helpful; never apologetic about the policy; never suggests the policy is optional

Must match an approved tone profile. Validate against tone registry. Common failure: 'friendly' tone leaking permissiveness into regulated refusal.

[ESCALATION_CONTACT]

Human or organizational contact for questions about the refusal

Contact your financial advisor or call 1-800-FIN-HELP for guidance

Must be a non-empty string with a valid contact method. Null not allowed. Validate format: phone, email, or URL. Log when escalation contact is provided to user.

[MODEL_CAPABILITY_BOUNDARY]

Statement of what the model cannot do, used to reinforce the refusal

I cannot provide personalized investment recommendations, predict market movements, or advise on specific securities

Must be a non-empty string aligned with platform policy. Cross-reference against [PERMITTED_CONTENT_TYPES] to ensure no contradiction. Version-controlled with policy updates.

Implementation Harness Notes

How to wire the refusal prompt into a production application with validation, logging, and escalation paths.

This prompt is a policy enforcement gate, not a conversational nicety. It should sit behind your application's orchestration layer, triggered whenever a user input or agent-generated plan touches investment recommendation territory. The prompt expects a structured input containing the user's request, any retrieved context, and a risk classification from an upstream triage step. Do not rely on this prompt alone to detect whether a request is an investment recommendation—pair it with a dedicated classification prompt or a keyword-based pre-filter that flags terms like 'should I buy,' 'best stock,' 'portfolio allocation,' or 'market timing.' The refusal prompt's job is to produce a compliant, consistent refusal when the system already knows the request falls in a regulated category.

Integration pattern: Wire this prompt into a decision node in your workflow. The upstream classifier outputs a risk_level enum (LOW, MEDIUM, HIGH, CRITICAL). For LOW, route to your normal response pipeline. For MEDIUM and above, invoke this refusal prompt with the original user query, the classifier's reasoning, and any relevant policy citations. The prompt returns a structured refusal object containing a refusal_text string, a safe_alternatives array, and a policy_citation field. Your application should validate that the output contains no buy/sell/hold language, no performance predictions, and no suitability implications before surfacing it to the user. Use a secondary LLM judge or a regex-based validator to check for leakage of recommendation language. If the validator flags the output, log the incident, increment a counter metric, and fall back to a static refusal message while alerting the safety engineering channel.

Model selection and latency: This is a safety-critical path, so prefer a capable model with strong instruction-following (GPT-4o, Claude 3.5 Sonnet, or equivalent). Latency is acceptable here—users waiting for a refusal is better than users receiving a bad recommendation. Set a timeout of 10 seconds. If the model call fails or times out, return a hardcoded refusal string from your application layer. Never fall through to an unguarded response. Logging and audit trail: Log every refusal invocation with the request_id, user_id, risk_level, policy_citation, the full prompt sent, the raw model output, and the validator result. These logs are your audit evidence if a regulator or internal compliance team questions why a particular response was surfaced. Store them in an append-only log system with retention aligned to your organization's compliance requirements (typically 3-7 years for financial services).

Human escalation trigger: If the risk_level is CRITICAL or if the user pushes back after a refusal (detected via a follow-up intent classifier), route the conversation to a human review queue. Do not let the model re-engage on the same topic. The escalation payload should include the full conversation history, the refusal that was shown, and the user's follow-up message. Testing before deployment: Run this prompt through a regression suite containing at least 50 test cases: direct recommendation requests ('What stock should I buy?'), implied requests ('I have $10k, where should I put it?'), performance predictions ('Will AAPL go up next quarter?'), suitability-adjacent language ('Is this ETF right for someone like me?'), and benign educational requests ('What's the difference between a stock and a bond?'). Measure refusal rate, false positive rate on educational content, and refusal consistency across rephrasings. Gate deployment on passing all safety-critical test cases and maintaining a false positive rate below 5% on educational content.

IMPLEMENTATION TABLE

Expected Output Contract

Define the exact shape of the refusal response so downstream systems can parse it reliably. Every field must be validated before the response reaches the user.

Field or ElementType or FormatRequiredValidation Rule

refusal_statement

string

Must contain a clear, direct refusal. Parse check: string is non-empty and does not imply a recommendation.

policy_citation

string

Must reference the specific policy boundary (e.g., 'personalized investment advice'). Schema check: value must match an approved policy key from [POLICY_CATALOG].

safe_alternative

string

Must offer a compliant alternative (e.g., 'factual security description'). Null check: field must not be empty or a generic apology.

educational_content

string | null

If provided, must be factual and general. Validation: run a secondary [SUITABILITY_CLASSIFIER] to confirm no implied buy/sell/hold language.

disclaimer

string

Must include a standard disclaimer (e.g., 'I cannot provide personalized investment advice'). Schema check: must match an approved disclaimer from [DISCLAIMER_LIBRARY].

risk_flag

boolean

Set to true if the input contained suitability implications or performance predictions. Approval required: if true, route to human review queue.

escalation_path

string | null

If risk_flag is true, provide a human escalation contact or link. Null allowed if risk_flag is false. Validation: if not null, must be a valid URI or email.

model_confidence

number

Confidence score (0.0-1.0) that the response contains no implied recommendation. Threshold check: if below [CONFIDENCE_THRESHOLD], retry or escalate.

PRACTICAL GUARDRAILS

Common Failure Modes

What breaks first when refusing investment recommendations and how to guard against it.

01

Suitability Implication Leakage

What to watch: The model refuses to recommend a stock but adds 'however, this might be suitable for aggressive investors.' This implies a recommendation and creates liability. Guardrail: Add explicit instruction to never characterize suitability, risk tolerance fit, or investor profile alignment. Test with prompts like 'I'm a risk-tolerant investor, should I buy X?'

02

Performance Prediction Drift

What to watch: The model correctly refuses to predict future performance but then states 'analysts expect growth' or 'the trend suggests upward movement.' These are predictions in disguise. Guardrail: Forbid all forward-looking statements including analyst consensus summaries, trend extrapolation, and price target mentions. Ground responses in historical data only.

03

Comparative Recommendation Framing

What to watch: The model refuses direct advice but says 'Stock A has a lower P/E ratio and higher dividend yield than Stock B.' This implies A is better and constitutes a comparative recommendation. Guardrail: When comparing securities, require neutral factual presentation without ranking, superiority language, or implicit preference. Test side-by-side comparison prompts.

04

Educational Content Overreach

What to watch: The model provides 'educational' content about investment strategies that is so specific to the user's situation it becomes personalized advice. Example: explaining dollar-cost averaging using the user's exact portfolio and contribution schedule. Guardrail: Educational content must remain generic and not reference the user's actual holdings, amounts, or timing. Strip personalization from educational responses.

05

Refusal Inconsistency Across Rephrasing

What to watch: The model refuses 'Should I buy Tesla stock?' but answers 'Is now a good time to invest in Tesla?' or 'What do you think about Tesla as an investment?' Users probe with rephrased questions. Guardrail: Classify intent, not surface phrasing. Use a refusal trigger list that covers buy/sell/hold, timing, allocation, recommendation, and opinion variants. Test with 20+ rephrasing patterns.

06

Disclaimer-Only Defense Without Refusal

What to watch: The model adds a disclaimer like 'This is not financial advice' but then proceeds to give specific investment guidance. Disclaimers do not cure regulated advice. Guardrail: Require substantive refusal before any disclaimer. The refusal must block the content, not decorate it. Test that disclaimers never appear alongside personalized investment content.
