This Skill addresses the pain point for A-share investors struggling to efficiently screen high-quality stocks in an information-overloaded market. It employs a quantitative model to dynamically filter and maintain a stock pool of up to 30 stocks from the entire market, based on the principle of "High-Tech × Small-to-Medium Market Cap × Strong Performance," and pushes buy/sell signals.
After installation, users can interact with the Skill using simple commands (e.g., querying the current stock pool, fetching the latest buy/sell signals). The Skill returns specific stock lists, timing scores (-10 to +10), and operation suggestions, helping users quickly capture investment opportunities.
It is well-suited for quantitative traders, data analysts interested in the A-share market, and individual investors seeking AI-assisted decision-making. These users typically possess some stock market knowledge and aim to enhance stock selection efficiency and decision-making科学性 (scientific rigor) through automated tools.
Usage Recommendation: It is recommended to use this Skill as an auxiliary decision-making tool rather than relying on it entirely. Users should exercise secondary judgment on the pushed signals based on their own risk tolerance and market understanding. Additionally, note that its stock pool capacity is limited (up to 30 stocks) and primarily focuses on high-tech and small-to-medium market cap sectors, which may not cover all investment opportunities.
Key Features
The core differentiator lies in its unique three-dimensional screening model of "High-Tech × Small-to-Medium Market Cap × Strong Performance," and it provides an intuitive, independent technical timing score (-10 to +10) to quantify buy/sell timing, rather than simple binary "buy/sell" signals.
Limitations
It is not suitable for scenarios requiring comprehensive market coverage, investment in large-cap blue-chip stocks, or in-depth fundamental analysis (e.g., corporate governance, industry policies).
FAQ
How accurate is this stock selection tool?
It provides reference signals based on a quantitative model and can serve as an auxiliary tool, but it does not guarantee 100% accuracy. Investment decisions should incorporate personal judgment.
How often is the stock pool updated?
The Skill maintains a dynamic stock pool. The specific update frequency depends on its internal logic, typically combining scheduled tasks with market data changes.
