MiaoXiang Smart Stock Screener
Screen A-shares from East Money's real-time stock database based on your specified criteria.
What Is MiaoXiang Smart Stock Screener?
MiaoXiang Smart Stock Screener (妙想智能选股器) is an automated market screening and fundamental analysis skill on EasyClaw. Designed specifically for active retail investors, portfolio managers, and quantitative researchers tracking Chinese markets, it connects directly with Eastmoney's real-time A-share stock database to scan and filter the entire market based on your specified financial and technical criteria — including price change percentages, P/E/B valuations, dividend yields, and sector nodes.
The skill is built for equity analysts identifying undervalued value stocks, swing-traders scanning for breakout momentum, and financial researchers monitoring sector capital flows.
The expected outcome is a structured, real-time Stock Screen List: a clean, spreadsheet-ready table showing matching stock tickers, names, current prices, change percentages, P/E valuations, market caps, and active sectors, saved directly to disk.
How MiaoXiang Smart Stock Screener Works
1. Analyze screening criteria. Provide your target parameters in natural language: e.g., "A-shares up more than 2% today," "CSI 300 stocks with P/E below 20x," or "list all stocks in the new energy sector."
2. Real-time database scan. The skill queries Eastmoney's active A-share database over HTTPS, scanning approximately 5,000 listed stocks on the Shanghai, Shenzhen, and Beijing exchanges.
3. Multi-metric filtering application. It applies your filters: sorting candidates by price, valuation ratios, daily volumes, or industry sector nodes, filtering out illiquid or suspended listings.
4. Data table structuring. The matching equities are compiled into a clean data table, with key metrics formatted side-by-side.
5. Output generation. Results are written directly to standard CSV and JSON files in your local workspace exports folder (`public/data/screener/`) and displayed instantly in your chat.

What Problems Does MiaoXiang Smart Stock Screener Solve?
1. Screening for undervalued CSI 300 value stocks
An investor wants to find stable, high-yield value stocks inside the CSI 300 index (沪深300). They ask the skill to screen: "Find CSI 300 stocks with a P/E ratio below 15x and dividend yield >4%." The skill scans the database and returns a ranked table of matching blue-chip stocks with exact metrics, ready for portfolio allocation.
2. Scanning for breakout momentum in the semiconductor sector
A swing trader is looking for hot stocks in the semiconductor sector. They run a technical screen: "List semiconductor stocks up more than 3% today with an average daily volume spike." The skill compiles the real-time list, highlighting the top 10 momentum leaders, allowing the trader to plan their daily trades.
3. Listing all active stocks in the new energy sector
An analyst wants to map the entire new energy sector landscape on Eastmoney. They request: "List all stocks in the new energy sector." The skill queries the sector indexes, returning a comprehensive table of all active listed energy stocks with current prices and capitalization metrics, saving hours of manual directory compiling.
4. Filtering out highly leveraged companies
Before adding a stock to their watchlist, an analyst wants to filter out high-risk entities. They request a screen excluding companies with a debt-to-equity ratio above 70%. The skill parses the balance sheets across the candidate list, filtering out leveraged firms and protecting their portfolio from default risks.
5. Automatically explaining available screening parameters
A beginner is confused about how to structure a stock screen. The skill's context logic detects their vague query and prompts politely: *"To help you screen stocks, would you like to filter by: (1) Daily gain/loss, (2) Valuation ratios (P/E, P/B), (3) Index boundaries (CSI 300), or (4) Specific industry sectors?"* guiding them to structure a valid query.
Example Workflow
An investor wants to screen for high-yield, low-valuation semiconductor stocks on the Shanghai exchange.
1. They open EasyClaw and activate MiaoXiang Smart Stock Screener.
2. They run: *"Screen for semiconductor stocks with P/E below 30x and daily gain over 2%."*
3. The skill queries the Eastmoney database, applies the multi-metric filters, and compiles the Screener List:
- Matching Stocks: Tickers like `600584` (JCET), `603501` (Asway), showing current quotes and P/Es.
- Data Saved: Written directly to `public/data/screener/semiconductor-screen-2026-06-10.csv`.
4. The investor downloads the CSV to analyze further in Excel.
A-share stocks screened, mapped, and exported in under 40 seconds.

What exchanges and markets are supported?
The skill covers all major Chinese A-share markets: Shanghai Stock Exchange (SSE), Shenzhen Stock Exchange (SZSE), and Beijing Stock Exchange (BSE), including ChiNext and STAR markets.
What is the "unstructured profile resolution" rule?
If you request an audit without providing a company name or ticker, the skill's context logic will politely prompt you for the specific ticker ID or company name to prevent duplicate or failed queries.
Are my search queries and audited company files kept private?
Yes. All financial queries, shareholder mappings, and file writes are executed entirely locally in your workspace session, keeping your strategic investment plans private.
Can I screen stocks by dividend yields?
Yes. You can specify: "screen for stocks with a dividend yield above 4.5% and cash flow positive," and the engine will calculate and filter the market based on yield metrics.

Yes. The skill automatically writes your screened lists, tickers, and valuation metrics to standard, structured JSON and CSV files under `public/data/screener/` in your local workspace, ready for Excel.
Does the skill support multi-sector filtering?
Yes. You can combine sector nodes in your queries, such as "list all stocks in the lithium battery AND electric vehicle sectors," and the engine will return the intersection.
Is an active internet connection required to run queries?
