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.

Default Workflow

1. Clarify scope if needed
2. Ticker / company / market

    • Price/FCF
    • DCF / owner earnings when useful
24. Compare to:
    • Own history
    • Peer group
    • Growth, margin, and risk profile

25. State whether valuation looks cheap, fair, expensive, or unclear.

28. Margin compression
29. Customer concentration
30. Debt refinancing

Scoring Framework

Use a 0-5 score for each dimension when the user wants a rating.

Final score is not a buy signal. Explain the judgment behind each score.

When More Detail Is Needed

Read references/metrics.md for metric definitions and interpretation. Read references/red-flags.md when checking accounting quality or risk signals. Read references/valuation.md when building a more detailed valuation section.

這個技能質量不錯，分析框架很專業，流程完整，從公司業務到財務資料再到估值風險都有覆蓋，還提供了實用模板。它很注重區分事實和觀點，不會亂給投資建議。不過它引用的一些補充資料檔案缺失了，內容不夠完整，想看詳細的指標解釋或估值方法時會找不到。如果能補上這些內容就更好了。
