Stock Screening by Late-Day Money Flow, Volume Ratio, and Limit-Ups

Summary

This Chinese stock screen combines relative trading activity, afternoon large-order net inflow, and past limit-up frequency. It proposes selecting stocks ranked among the top 100 by volume ratio and afternoon net inflow, and requiring at least two limit-up events within 500 days. The note interprets these signals as indicators of fund inflow and market attention, emphasizing short-term activity.

The discussion warns that sentiment-driven selections may be volatile, that capital-flow measures are uncertain, and that the screen may miss longer-term trends and company fundamentals. It suggests adding turnover, support and resistance analysis, and valuation measures. The final proposed logic expands the initial screen with these additional filters, but the document reports no backtest, performance results, or evidence that the proposed additions improve predictive accuracy.

Key ideas

• The initial screen selects top-ranked stocks by volume ratio and afternoon large-order net inflow.
• It also requires at least two limit-up events within 500 days.
• The method emphasizes short-term activity and may select volatile stocks while overlooking fundamentals and long-term trends.
• Turnover, technical levels, and valuation measures are suggested as additions, but their impact is not tested.
