Selecting Chinese Stocks by Price Movement and Auction Net Buying

Summary

This stock-screening proposal combines three filters: price amplitude above one percent, a listing age greater than one year, and positive net buying attributed to major participants during the opening auction. The stated rationale is to seek active stocks, exclude newer listings that may be unusually volatile, and favor names with a positive auction-period flow reading. The document presents the screen as a selection rule rather than a complete entry, exit, or portfolio strategy.

It cautions that the screen omits company fundamentals, industry conditions, and macroeconomic influences, and notes that selected stocks may still move sharply. It suggests adding technical indicators and using stop-loss and take-profit levels. The accompanying sample code has limitations: it does not visibly implement the listing-age filter, and its amplitude calculation uses the close-to-previous-close change rather than a high-low range. No backtest results or evidence of predictive value are supplied.

Key ideas

• The proposed screen requires price amplitude above one percent, listing age over one year, and positive opening-auction net buying.
• The stated intent is to favor active stocks with positive auction-period buying while filtering newer listings.
• The article warns that fundamentals, industry conditions, and macroeconomic factors are not included.
• Risk controls and additional indicators are suggested, but no tested results are reported.
• The sample implementation does not visibly apply the listing-age rule and calculates close-to-previous-close change as amplitude.
