stock-screener	Multi-factor A-share stock screening workflow for medium-to-short-term selection

What I Do

Guide the agent through a structured stock screening process:

1. Understand user preferences (industry, market cap, holding period)
2. Assess market environment via market-overview skill
3. Call screening tools to find candidates
4. Score and rank candidates by multi-factor model
5. Output Top 3-5 picks with rationale, position sizing, and cost estimates

Capital Context (CRITICAL)

The user has ~5万 RMB capital. Every recommendation must account for this:

• Stock price filter: each recommended stock must cost ¥10–¥50 per share so the user can afford at least 1手 (100 shares). Stocks >¥200 need explicit justification (concentrated bet). Stocks >¥500 are completely inaccessible — never recommend them.
• Portfolio concentration: default output is 3–5 stocks, not 10+. The user holds 2–4 stocks max.
• Position sizing: for each recommended stock, suggest a specific lot count and total cost in RMB.
• Transaction cost: for each recommended position, calculate estimated one-way cost (commission + stamp tax). Surface it alongside the position suggestion.

Position Sizing Table (5万 context)

Market Signal	Total Exposure	Max Per Stock	Holding Count
Strong uptrend	35,000–40,000 (70–80%)	10,000–15,000	3–4 positions
Neutral/sideways	15,000–25,000 (30–50%)	5,000–10,000	2–3 positions
Weak/downtrend	<15,000 (<30%)	<5,000	1–2 positions

Affordability Check

Before recommending any stock, verify:

股价 × 100 shares ≤ 计划分配给该股的仓位金额

Example: ¥38 stock × 100 = ¥3,800. With ¥10,000 allocation, the user can buy 2手 (200 shares, ¥7,600).

Screening Dimensions

• Technical (35%): Trend strength, moving average alignment, volume-price coordination, RSI position
• Capital Flow (30%): Main fund net inflow trend, northbound capital, large order ratio
• Fundamental (25%): PE percentile, ROE, profit growth, revenue growth
• Sentiment (10%): News heat, analyst rating direction

When to Use Me

Use when the user asks to:

• Find/screen stocks for investment
• Get stock recommendations
• Filter stocks by any criteria

Workflow

1. Ask the user about preferences if not specified (sector, style, time horizon)
2. Load market-overview skill to check if market is favorable and get position sizing signal
3. Use stock-screen tools to filter candidates (default top_n=5)
4. For each top candidate, verify affordability:
   • Check share price, calculate minimum buy cost (price × 100)
   • Cross-check against the position sizing budget
   • Filter out any stock the user cannot afford
5. For remaining candidates, run quick analysis with relevant tools
6. Present a ranked list with:
   • Rank and composite score (0-100)
   • Key strengths (why buy?) and risks (what can go wrong?)
   • Suggested position: lot count × share price = total cost
   • Estimated transaction cost for this position
   • Stop-loss price in both ¥ and percentage

Output Format Example

Rank	Stock	Price	Score	Position	Cost	Stop-Loss	Rationale
1	600XXX	¥28.5	82	3手 (300股) = ¥8,550	交易费~¥14	¥25.7 (-10%, -¥855)	放量突破+主力净流入
