Repo Structure

Quick Start

Stock Research (股票投资尽调)

# Start Claude Code
claude

# Set model (optional, but recommended)
/model opus

# Execute stock research
/stock-research [股票代码或公司名称]

# Examples:
/stock-research 600519              # 贵州茅台 (A-share)
/stock-research AAPL                # 苹果公司 (US)

Stock Investment Research

8-Phase Due Diligence Process

Investment Style Adaptation

The system adapts research approach based on investment style:

Quality Standards

Mandatory Cross-Validation:

• ✅ Profit vs. cash flow (OCF/NI ratio analysis)
• ✅ Company vs. peer comparison (key ratios, margins)
• ✅ Bear case analysis (3-5 key risks identified)

Citation Requirements:

• Every factual claim must include: Author, Date, Title, URL
• Source quality rated (A-E scale)
• A-grade sources: Annual reports, regulatory filings
• B-grade: Industry reports, analyst research
• C-grade: News articles, expert commentary

Signal Rating (based on fundamentals only):

• 🟢🟢🟢 Strong Buy: Significant margin of safety, strong moat, attractive valuation
• 🟡🟡🟡 Hold: Fairly valued or limited margin of safety
• 🔴🔴 Avoid: Overvalued, deteriorating fundamentals, excessive risks

Example Usage

User: /stock-research 贵州茅台 600519

Claude: 我可以帮您研究贵州茅台。让我先了解您的投资需求：

       1. 投资风格：价值投资/成长投资/困境反转/红利投资？
       2. 持有周期：短期(<6月)/中期(6-18月)/长期(1-3年以上)?
       3. 关注重点：生意质量/财务质量/估值/公司治理 (选2-3个)
       4. 风险偏好：保守/平衡/激进？

User: 价值投资，长期持有3年以上，关注：生意质量、公司治理、估值，风险保守

🟡🟡🟡 Hold / Fairly Valued

Investment Thesis:
茅台是中国领先的白酒品牌，拥有强大的品牌护城河和定价能力。然而当前估值（P/E 32x）安全边际有限。建议继续持有现有仓位，但新投资应等待10-15%回调至¥1,750-1,850区间。

Key Metrics:
- Market Cap: ¥2.8T
- P/E (TTM): 32x (above 5-year average)
- Gross Margin: 91.2%
- ROE: 31%
- Moat Rating: 5/5 (Very Strong)

Top 3 Reasons to Consider:
1. Unassailable brand moat with 800-year heritage
2. Exceptional margins (91% gross, 53% net)
3. Strong cash generation (OCF/NI > 1.0)

Top 3 Reasons to Avoid:
1. Full valuation (P/E 32x, limited margin of safety)
2. Regulatory risk (government scrutiny of luxury pricing)
3. Competitive intensification (Wuliangwa narrowing gap)

Monitoring Checklist:
✅ Strengthen: Price pulls back 10-15% to ¥1,750-1,850
❌ Exit: Price drops below ¥1,300 (-35%), net margin < 45%

Customization

Adapting Stock Research Parameters

The system automatically adapts based on:

1. Investment Style:

   • Value: Emphasize balance sheet, normalized earnings, margin of safety
   • Growth: Emphasize TAM, competitive positioning, growth sustainability
   • Turnaround: Emphasize liquidity, solvency, catalysts
   • Dividend: Emphasize payout sustainability, FCF generation

2. Holding Period:

   • Short-term (<6 months): Focus on near-term catalysts, sentiment
   • Medium-term (6-18 months): Balanced approach
   • Long-term (1-3+ years): Emphasize business sustainability, moat, intrinsic value

3. Risk Tolerance:

   • Conservative: Add filters (debt limits, minimum profitability)
   • Balanced: Standard risk checks
   • Aggressive: Accept higher volatility, focus on upside scenarios

Customizing Output

Adjust research parameters by answering the question-refiner's questions with your specific needs:

• Geographic focus (China, US, global)
• Timeframe (3 years, 5 years, 10 years of data)
• Source preferences (annual reports only, include news, etc.)
• Language (Chinese, English, or bilingual)
• Valuation methods (DCF required? sum-of-parts?)
