Chinese Stock Screening with Afternoon Net Inflows, RSI, and Relative Gains

Summary

This note describes a Chinese equity screen requiring RSI below 65, positive afternoon large-order net inflow, and strong performance since 2021, with the stated final rule focusing on stocks in the top decile for both net inflows and cumulative gains. The rationale combines a momentum measure, a technical indicator, and a short-term flow signal. The Python example adds further checks involving trading volume, market-list data, prior limit-up activity, and KDJ conditions, so its actual selection process is more involved than the concise rule.

The author cautions that the approach depends on technical and flow data while omitting company results and industry prospects. Ranking past gains may select crowded or recently hot stocks, and historical strength alone does not establish future potential. The document suggests adding fundamental measures and other indicators. It provides example code but no backtest, return figures, or validation of the signals; discrepancies between the stated logic and implementation also limit reproducibility.

Key ideas

• The stated screen combines RSI below 65, positive afternoon large-order inflow, and top-decile historical gains.
• The strategy uses price momentum and transaction-flow information to rank Chinese stocks.
• The code example adds volume, limit-up history, and KDJ checks beyond the main written criteria.
• Reliance on past gains can favor crowded or temporarily hot stocks.
• The note identifies missing fundamental context and provides no performance validation.
