## What I Do

Evaluate the overall A-share market environment to determine:
1. Whether the market is favorable for medium-term trading
2. Suggested position sizing in RMB (capital-aware, for ~5万 account)
3. Current hot sectors and rotation patterns
4. Key risk factors

## Capital Context (CRITICAL)

**The user has ~5万 RMB capital.** Position sizing must be translated to concrete RMB amounts, not abstract percentages alone.

### Position Sizing for 5万 Account

| Signal | Total Position | Max Per Stock | Holding Count |
|--------|---------------|---------------|---------------|
| **Heavy (bullish)** | ¥35,000–40,000 (70–80%) | ¥10,000–15,000 each | 3–4 positions |
| **Moderate (neutral)** | ¥15,000–25,000 (30–50%) | ¥5,000–10,000 each | 2–3 positions |
| **Light (bearish)** | <¥15,000 (<30%) | <¥5,000 each | 1–2 positions |

Always present both: percentage of capital AND the corresponding RMB range.

## Assessment Dimensions

### Index Trend
- Shanghai Composite (000001), Shenzhen Component (399001), ChiNext (399006)
- Direction, strength, and stage of trend
- Key support/resistance levels
- 20/60-day MA relationship

### Market Breadth
- Advancing vs declining stocks ratio
- Volume trend (expanding / contracting)
- New highs vs new lows
- % of stocks above 20-day MA

### Sector Rotation
- Leading and lagging sectors
- Sector fund flow
- Continuity of sector trends (how many days in a row?)

## When to Use Me

Use when the user asks to:
- Check market conditions
- Decide position size
- Understand sector rotation
- Before running any stock screening

## Workflow

1. Fetch major index data via `stock-data index`
2. Fetch sector performance via `stock-data sector`
3. Analyze market breadth indicators
4. Identify sector hotspots and rotation signals
5. Output a structured market assessment:

### Output Format

1. **Market Signal**: Strong / Moderate / Weak — with justification
2. **Index Summary**: each index trend + key level
3. **Market Breadth**: breadth reading and what it means
4. **Hot Sectors**: top 3–5 sectors with momentum
5. **Position Recommendation**:
   - Signal-based allocation in RMB and %
   - Max per stock in RMB
   - Suggested holding count
6. **Key Risks**: specific market risks to watch this week

## Risk Disclaimer

Always remind the user: results are for reference only. Market conditions can change rapidly. Position sizing is a suggestion, not financial advice.
