   pip install akshare
   ```

2. **Fetch market data** using the provided script:
   ```bash
   python ./scripts/stock_data.py <stock_code> [--days 30]
   ```

3. **Fetch news** using the provided script:
   ```bash
   python ./scripts/stock_news.py <stock_code> <stock_name>
   ```

4. **Analyze and score** using the methodology in `./references/analysis-guide.md`

## Analysis Methodology

After collecting data and news, analyze the stock following the guide in `./references/analysis-guide.md`. Key points:

### Scoring System (-5.00 to +5.00)

| Range | Signal | Typical Triggers |
|-------|--------|-----------------|
| +/-4.0 to +/-5.0 | Strong | Major breakout, significant policy change, critical news |
| +/-2.0 to +/-3.9 | Moderate | Policy tailwind, sector rotation, fundamental shift |
| +/-0.5 to +/-1.9 | Weak | Sentiment shift, valuation deviation, volume change |
| 0.0 to +/-0.4 | Neutral | Insufficient info or no clear direction |

### Multi-dimensional Analysis

Always consider ALL dimensions — do not rely on just one:

- **Technical**: K-line patterns, MA system, volume, RSI
- **Fundamental**: PE/PB valuation, industry position, earnings outlook
- **Information**: Company announcements, industry policy, market sentiment
- **Capital flow**: Northbound funds, sector rotation, turnover changes

When dimensions contradict each other (e.g., bullish volume but overvalued), explicitly state the conflict.

### Report Format

Present analysis as:

```
## {Stock Name} ({Stock Code}) Analysis Report
Date: {YYYY-MM-DD}

**Score: {score}** ({signal level})

### Key Findings
- [Bullish factors]
- [Bearish factors]
- [Risk factors]

### Technical Analysis
[MA status, RSI, volume trend]

### Fundamental Analysis
[PE/PB, industry context]

### News & Sentiment
[Key news items and their implications]

### Conclusion
[Balanced summary, 2-3 sentences]

## Special Cases

- **Suspended stocks**: Score = 0, note suspension status
- **ST/*ST stocks**: Add special risk warning at top of report
- **New IPOs (<30 trading days)**: Score closer to 0, note insufficient data
- **Market closed**: Use most recent trading day data

## Common Pitfalls

- Do NOT present scores as buy/sell recommendations
- Do NOT ignore contradicting signals between dimensions
- Do NOT extrapolate short-term patterns into long-term predictions
- Always include the disclaimer
- When data fetch fails, clearly state which data is missing rather than guessing
