Chinese Stock Screening with Intraday Range, Company Quality, and Opening Gains

Summary

This note outlines a Chinese equity screen combining a daily price range above 1%, a qualitative preference for sound companies, and a gain below 6% at 9:25 a.m. It also suggests considering profitability, growth, return on equity, market capitalization, technical measures, and broader market conditions. The accompanying formula and Python example are presented as implementation references, but their calculations do not cleanly match the stated screen: they use closing-price comparisons and other measures rather than consistently applying the 9:25 condition or defining company quality.

The rationale is that some price movement may identify active stocks, while a moderate opening gain is intended to limit risk. The author cautions that focusing on the opening move can exclude promising stocks and that the time-specific filter may reduce the screen’s timeliness and general applicability. No backtest, performance evidence, or detailed definition of the qualitative company filter is provided, so the proposed selection logic should be treated as an informal screening idea rather than a validated strategy.

Key ideas

• The proposed screen combines a daily range above 1% with a qualitative company filter and an opening gain below 6%.
• The document suggests adding financial, technical, and market measures to broaden the assessment.
• Its sample calculations do not consistently implement the stated 9:25 a.m. condition.
• The author notes that the time-specific gain limit may exclude promising stocks and may not generalize well.
• No backtest or performance evidence is supplied.
