A Chinese Stock Screen Using Net Buying, Float Market Value, and Opening Gap

Summary

This document describes a Chinese-equity screen requiring a reported increase in holdings above 5%, float market value between 5 billion and 10 billion yuan, and a 9:25 opening gain below 6%. The post interprets the net-buying measure as possible buying interest, the market-value band as a balance between liquidity and activity, and the opening-gap limit as a way to avoid sharp opening moves.

It acknowledges that the filter relies on historical data, can miss stocks outside its chosen size and gap ranges, and may include companies with weak results or financial risks. It recommends adding financial-health and technical filters or using a longer observation window. No backtest or measured outcomes are provided, and the sample code expresses the opening-gap comparison ambiguously, so the screening logic needs clarification and validation before use.

Key ideas

• The screen combines a net-buying threshold, a bounded float market value, and a capped 9:25 opening gain.
• The post presents the conditions as proxies for buying interest, tradability, and a relatively stable open.
• The method can omit candidates and does not account for company financial quality.
• The code's opening-gap expression is ambiguous, and the document supplies no performance results.
