AI Methodology & Limitations

Stock Expert AI uses Gemini 2.0 Flash as the primary analysis engine, OpenAI for OCR, and Claude for Moon AI chat. Every AI output passes through a 6-layer validation pipeline including numeric integrity, ticker consistency, and source data cross-checks. Known limitations: AI scores do not predict future performance; financial decisions should be made with a licensed advisor.

Last Updated: May 4, 2026

1. AI Models in Production

Stock Expert AI uses a multi-model architecture, selecting the best-fit AI engine for each task:

  • Gemini 2.0 Flash (Primary): Dossier generation, content authoring, multilingual translation. Selected for long-context handling, structured JSON output reliability, and cost efficiency at our scale (35,000+ stocks).
  • OpenAI GPT-4o: Portfolio screenshot OCR, prediction assistance, content moderation. Used where precise visual reasoning or instruction-following is critical.
  • Claude: Moon AI chat assistant. Selected for conversational quality, refusal discipline on speculative requests, and grounding adherence.

2. Hallucination Prevention

Every AI output passes through a 6-layer validation pipeline before reaching production:

  1. Numeric integrity: Generated figures (revenue, P/E, market cap) cross-checked against source data within ±2% tolerance.
  2. Ticker consistency: All ticker mentions in generated text must match the page entity. Mismatches trigger regeneration.
  3. Length ratio: Translated paragraphs preserve length within adaptive ratio bounds (prevents content collapse).
  4. Paragraph preservation: ≥60% structural fidelity between source and AI output.
  5. HTML tag validation: No malformed markup, no template variable leakage.
  6. Title sanity: Length 5-300 chars, no system prompt artifacts, no model self-references.

Failures trigger up to 2 retry-with-feedback attempts. Persistent failures route to a manual review queue.

3. Source Data Grounding

AI models are constrained to source data — no speculation or invented numbers. Prompts include explicit grounding instructions:

  • "ONLY use facts from the provided source data. If a fact is not in sources, output 'Unknown'."
  • "NO speculation or estimation. No invented numbers."
  • "Time-awareness: Categorize catalysts as 'Upcoming:' or 'Ongoing:'. Do not list past events as future catalysts."
  • "COMPLIANCE: Never use advisory phrases like 'good buy', 'should buy', 'compelling investment'. Present facts neutrally."

4. AI Editorial Personas (Transparent Disclosure)

Market Journal and stock analysis articles are attributed to AI editor personas (e.g., Dakota Finch, Chase Merrington, Alex Sterling). These are not real people. They are AI personas representing distinct analytical styles within our system. The pattern follows industry transparency standards (The Atlantic's Bertie, Washington Post's Heliograf, Bloomberg's Cyborg).

Every author profile page carries an explicit "AI Editor" disclosure banner with editorial accountability attributed to founder Sedat ANAK via schema.org Person + agent reference.

5. Known Limitations

  • Not predictive: AI scores are pattern-recognition signals on historical data, not future predictions.
  • Validation isn't perfect: Despite 6-layer validation, occasional inaccuracies may surface. Reported errors reviewed within 24 hours.
  • Market regime sensitivity: Signals trained on past regimes may underperform in unprecedented market conditions.
  • Coverage gaps: Recently listed stocks, micro-caps, and OTC tier names may have limited data depth.
  • No real-time AI: AI dossiers refresh on material events, not on every price tick. Real-time signals come from FMP/Alpaca quote feeds, not AI inference.
  • Translation drift: Multilingual content (TR/ES/DE/ZH) is AI-translated; rare nuance loss possible despite a strict 1:1 translation policy.

6. Regulatory & Legal Status

Stock Expert AI is not a registered investment advisor under the Investment Advisers Act of 1940 or any equivalent regulation. The platform provides educational research tools and AI-generated analysis for informational purposes only.
