Stock Fundamental Analysis
Use this skill to produce disciplined, evidence-based fundamental analysis for public companies.
Core Rules
- Do not provide personalized financial advice or guaranteed predictions.
- Always separate facts, assumptions, and opinion.
- Prefer primary sources: 10-K, 10-Q, annual reports, earnings releases, investor presentations, transcripts, and official guidance.
- Use recent market data only after checking live sources when available.
- If data is missing or stale, say so clearly.
- Never rely on one metric. Combine business quality, financial quality, valuation, and risk.

Scoring Framework
Use a 0-5 score for each dimension when the user wants a rating.
| Dimension | Score Guide |
|---|---|
| Business quality | Moat, market position, recurring demand |
| Growth | Revenue growth, TAM, reinvestment runway |
| Profitability | Margins, ROIC, operating leverage |
| Cash flow | FCF quality, conversion, capex intensity |
| Balance sheet | Debt, liquidity, maturity risk |
| Management | Capital allocation, guidance credibility, incentives |
| Valuation | Price vs quality/growth/risk |
| Risk | Lower score means higher risk |
Final score is not a buy signal. Explain the judgment behind each score.
