Chinese Stock Screen Using Capital Strength, Market Cap, and Opening Gain

Summary

This Chinese A-share screening idea combines three filters: rank stocks by capital-flow strength, require market capitalization below 10 billion yuan, and exclude companies reporting losses. It also limits the 9:25 a.m. gain to below 6%, aiming to avoid stocks that have already opened sharply higher. The post presents capital strength as a proxy for investor attention and describes smaller capitalization and modest opening gains as ways to constrain risk.

The document offers a qualitative rationale rather than evidence from a backtest or live results. It notes that the screen omits other relevant considerations, including company finances and industry prospects, and may exclude promising stocks that fail its criteria. It suggests adding fundamental and technical measures and a stop-loss rule, but supplies no tested specifications for those additions. The sample code discussion is incomplete, so the screening concept is clearer than its implementation details.

Key ideas

• The screen ranks stocks by capital-flow strength and filters for market capitalization below 10 billion yuan.
• It excludes loss-making companies and stocks whose 9:25 a.m. gain is 6% or higher.
• The post offers investor attention and reduced exposure to sharp opening moves as rationales for the filters.
• It provides no backtest evidence and warns that the screen omits company and industry fundamentals.
