This tool addresses challenges faced by A-share investors, such as information overload, difficulty in stock selection, and uncertainty in timing buy/sell decisions. It employs a quantitative model to automatically maintain a dynamic stock pool of up to 30 stocks based on the principle of "high-tech × small-to-medium market capitalization × strong performance," and independently calculates a technical timing score (-10 to +10) for each stock, providing buy/sell timing suggestions. The tool also supports scheduled message notifications to help users promptly access critical information.
After users configure relevant parameters (e.g., stock pool size, screening criteria weights), the tool runs automatically. It periodically scans the A-share market, updates the stock pool according to preset rules, and calculates the timing score for each stock. When buy/sell signals meeting preset conditions are detected, users are notified via integrated messaging channels. The entire process is automated, eliminating the need for continuous manual monitoring.
This tool is well-suited for individual investors, quantitative traders in the A-share market, and data analysts interested in stock analysis. It is particularly beneficial for investors who recognize the value of combining fundamental and technical analysis but lack the time or technical expertise for in-depth quantitative analysis. They can use this tool as a reference to aid decision-making, improving stock selection efficiency and the scientific basis of their decisions.
Users are advised to treat this tool as an auxiliary reference rather than the sole basis for decisions. Investing involves risks; decisions should be made considering personal risk tolerance and investment strategies. When first using the tool, it is recommended to test signal effectiveness with small capital or simulated trading. Regularly monitor updates to the stock pool and changes in timing scores, understand the underlying logic, and adjust the tool's configuration parameters as market conditions evolve.
Key Features
The core differentiator lies in its unique tripartite screening model—"high-tech × small-to-medium market capitalization × strong performance"—combined with an independent, quantitative technical timing score (-10 to +10) to precisely determine buy/sell timing, rather than merely providing a stock list.
Limitations
It is not suitable for investors pursuing ultra-short-term high-frequency trading, those who rely entirely on subjective judgment, or those who distrust quantitative models.
FAQ
How accurate is this stock selection tool?
The tool provides reference signals based on quantitative models; past performance does not guarantee future results, and signals should be combined with personal judgment and risk control.
Is programming knowledge required to use it?
Basic usage requires no programming, but advanced configuration and custom strategies may require some technical understanding.
