Chinese Stock Screen Using Opening Gap, Moving Averages, and Volume Ratio

Summary

This Chinese equity screen combines three conditions: the opening price at 9:25 must be less than 6% above the previous close, the 20-day moving average must be above the 120-day average, and stocks are ranked by volume ratio, with the top 100 selected. The post interprets the moving-average relationship as a sign of stronger short-term than long-term trend and the opening-gap cap as a way to avoid stocks with a large early jump.

The article also identifies limits: the screen omits company fundamentals, and its opening-price condition does not account for other market information such as trading volume or order-book conditions. It suggests adding turnover, volume, fundamentals, and technical measures. It provides no backtest, performance figures, or evidence that the proposed filters predict returns; the claimed rationale is qualitative, and the final strategy description is cut off.

Key ideas

• The screen selects stocks whose 9:25 opening gain over the previous close is below 6%.
• It requires the 20-day moving average to be above the 120-day moving average.
• It ranks stocks by volume ratio and selects the top 100.
• The post proposes adding turnover, volume, fundamental, and technical information.
• No backtest or quantitative evidence is provided to support the selection rules.
