This Skill is designed to help A-share investors efficiently identify promising stocks and capture trading opportunities in an era of information overload. It employs quantitative models to automatically screen a vast universe of stocks, selecting those that align with the principles of "high-tech, small-to-medium market cap, and strong performance," and dynamically maintains this portfolio.
Once installed, the Skill runs continuously, automatically maintaining a dynamic stock pool of up to 30 stocks. It analyzes these stocks based on preset quantitative models (combining fundamental and technical analysis) and pushes real-time buy/sell signals to users. Additionally, it provides an independent "Technical Timing Score" (ranging from -10 to +10) to assist in judging specific entry and exit points.
This Skill is well-suited for quantitative traders, data analysts interested in A-share investment, and individual investors seeking AI-assisted decision-making. It aims to automate complex market analysis, offering users a clear framework for decision reference.
Usage Recommendation: Please treat the Skill's trading signals and Timing Score as important auxiliary references, not the sole basis for decisions. It is recommended to make comprehensive judgments considering your own risk tolerance and market understanding. Note that the stock pool is dynamically updated, past performance does not guarantee future results, and investing carries risks.
Key Features
The core differentiator lies in its unique three-factor dynamic screening model ("High-Tech × Small-to-Medium Market Cap × Strong Performance") and the provision of an independent "Technical Timing Score" ranging from -10 to +10, specifically designed for refined judgment of trading timing rather than simple binary buy/sell signals.
Limitations
This Skill is primarily based on quantitative models and historical data. It is not suitable for ultra-short-term trading or event-driven investments that require deep understanding of company fundamentals, industry policies, or breaking news events.
FAQ
How often is the stock pool recommended by this Skill updated?
The Skill dynamically maintains the stock pool. The specific update frequency depends on the model settings and changes in market data, typically occurring daily or in real-time.
How do I use the Technical Timing Score? What do negative and positive scores represent?
The Timing Score ranges from -10 to +10. A negative score indicates technical weakness or a sell signal, while a positive score indicates technical strength or a buy signal. The larger the absolute value, the stronger the signal.
