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-research 腾讯 00700.HK       # 腾讯控股 (HK)

The system will:

1. Ask about your investment style (价值/成长/困境/红利), holding period, risk tolerance
2. Deploy ~28 parallel research agents across 7 phases
3. Generate comprehensive due diligence report in RESEARCH/STOCK_[ticker]_[company]/

Time: 2-4 hours for standard due diligence

Investment Style Adaptation

The system adapts research approach based on investment style:

| Style | Focus | Valuation Methods | Key Metrics | |-------|-------|-------------------|-------------| | Value (价值投资) | Intrinsic value, margin of safety | P/B, EV/EBITDA, DCF (conservative) | P/B, normalized earnings, FCF yield | | Growth (成长投资) | TAM, competitive positioning | PEG, DCF (aggressive), user models | Revenue growth, moat, TAM penetration | | Turnaround (困境反转) | Liquidity, solvency, catalysts | Liquidation value, option value | Debt ratios, cash runway, catalyst timeline | | Dividend (红利投资) | Dividend sustainability | DDM, FCF yield, yield comparison | Dividend yield, payout ratio, FCF coverage |

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)?

       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%
