Chinese Stock Screening with Turnover, Float Size, Volume, and Opening Gaps

Summary

This document describes a Chinese equity screen combining a turnover range, a cap on circulating shares or market value, a minimum current volume, and an opening price above the prior close. The intended rationale is to find liquid, actively traded stocks showing positive short-term price action. It also suggests adding fundamental and growth measures to refine candidates, although those additions are not specified as part of the initial rules.

The post provides formula and Python examples, but the criteria are inconsistent: the prose gives a turnover range of 3% to 12%, while the final formula and sample code do not implement that range reliably. The share-count and market-value descriptions also differ, and the Python turnover bounds conflict. No backtest results or performance evidence are presented. The author warns that technical screening can encourage chasing and omit company fundamentals, and recommends broader financial and growth analysis before using the screen.

Key ideas

• The screen combines turnover, circulating size, current volume, and a positive opening gap.
• It frames high turnover and an opening above the prior close as signs of trading activity and short-term momentum.
• The written criteria and code examples contain inconsistencies, so the rules need clarification before implementation.
• The post presents no performance results and cautions that technical filters omit long-term fundamentals.
