market-overview	Assess current A-share market environment including index trends, market breadth, sector rotation, and position sizing recommendation

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.

• Shanghai Composite (000001), Shenzhen Component (399001), ChiNext (399006)

When to Use Me

Use when the user asks to:

• Check market conditions

• Understand sector rotation
• Before running any stock screening

Workflow

6. Key Risks: specific market risks to watch this week

Risk Disclaimer
