Stock Screening by Morning Price Change and Capital Flow Rankings

Summary

This Chinese stock screening proposal combines three signals: an opening price gain below 6% at 9:25, a high volume ratio, and a high ranking for prior-day net inflows attributed to large market participants. The article describes ranking stocks by volume ratio and net inflow, then applying the opening-price condition. It recommends checking the resulting candidates manually and validating the flow and activity measures with other indicators or technical analysis.

The document gives no historical test, trade rules, or evidence that these rankings predict sustained performance. It warns that volume ratios and reported net flows may be unreliable or manipulated, while opening moves can reflect shifting market sentiment and bring volatility. The code examples merely call named indicator functions and do not show how to combine their outputs into a working screen. The proposal is therefore an outline for candidate selection, not a fully specified or validated strategy.

Key ideas

• The screen combines a morning opening gain below 6% with rankings for volume ratio and prior-day net inflows.
• The proposed rankings select up to the top 100 stocks for each capital activity measure.
• The article recommends validating these measures and manually reviewing selected stocks.
• It warns that flow metrics may be unreliable and opening moves may be sentiment driven.
• The code sketch does not specify a complete selection process, and no performance evidence is provided.
