Ranking Stocks by Volume Ratio and Prior-Day Net Inflows

Summary

This Chinese equities selection concept ranks stocks by volume ratio and by prior-day net inflows attributed to major investors, retaining the top 100 in each ranking. It also states a 2021 start date, though the practical meaning of that date in the selection process is unclear. The proposed rationale is to focus on securities showing elevated trading activity and recent reported capital inflows.

The article provides no backtest, return data, benchmark, or rules for combining the rankings into a final portfolio. It acknowledges that the screen omits company performance and industry outlook, and recommends adding financial and profitability measures. Its sample Python is incomplete and appears not to implement the stated volume-ratio and net-inflow data correctly, so it should not be relied on as executable strategy logic. The idea is a rough screening premise, not validated evidence of persistent upside.

Key ideas

• The proposed screen ranks stocks by volume ratio and prior-day major-investor net inflows, selecting the top 100 for each measure.
• The article associates high activity and reported inflows with increased market attention, but does not establish predictive value.
• It recommends adding company financials and profitability to address omitted factors.
• The code example is incomplete and does not reliably express the stated selection logic.
