Screening Main Board Stocks by Auction Value, Range, and Opening Gains

Summary

This Chinese equity screen selects main board stocks with a daily amplitude above 1, an opening gain greater than 1% relative to the prior close, and a top-five rank by auction trading value. The proposed combination targets active stocks showing both price movement and positive opening momentum. The document includes formula and Python examples, but gives no historical test, performance figures, or evidence that these filters predict returns.

The post notes that this short-term approach can overlook long-run company value and fundamentals. It suggests adding market capitalization, profitability, growth, and technical indicators for broader analysis. The main board restriction is described as a way to avoid small-cap risk, but the post does not demonstrate that it achieves that goal. The sample code is illustrative and its ranking and data references would need to be checked against the chosen platform before use.

Key ideas

• The screen ranks stocks by auction trading value and keeps the top five.
• It requires daily amplitude above 1 and an opening price more than 1% above the prior close.
• The universe is restricted to main board stocks.
• The post warns that short-term price filters omit fundamentals and provides no performance test.
