Screening Chinese Stocks by Price Range, Large-Order Flow, and Turnover

Summary

This post describes a short-term Chinese stock screen combining price amplitude, a ranking by net large-order volume, and a minimum prior-day turnover threshold. Its stated rationale is to find actively traded stocks with notable price movement. The post also refers to excluding special-treatment or suspended stocks and ranking candidates by recent performance, though its example formulas and Python sketch do not consistently implement the headline criteria.

The author cautions that these technical and trading-activity filters do not assess long-term value or company fundamentals, and that a simple screen may miss promising firms or perform poorly as market conditions change. Suggested extensions include adding fundamental, macroeconomic, trend, industry, and market-theme information, with machine-learning methods mentioned as a possible screening aid. No performance results or validation evidence are presented, so the screen should be treated as an idea rather than an established strategy.

Key ideas

• The proposed screen combines price amplitude, large-order net-flow ranking, and prior-day turnover.
• It aims to identify volatile and actively traded Chinese stocks over a short horizon.
• The example implementations do not fully align with the stated screening logic.
• The post gives no backtest or performance evidence for the screen.
• The author recommends adding fundamental and broader market context to improve selection.
