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

Summary

This article outlines a short-term stock screen combining a daily price-range threshold, a large-order net-flow ranking, and appearance on the previous day’s market activity list. It argues that range and large-order measures may capture trading activity and sentiment, while recent visibility could attract attention and short-term buying. A formula reference and a Python example illustrate how to check price movement, trading data, and prior-day list inclusion. The example also uses turnover as a proxy for the large-order condition, so its implementation does not exactly match the stated ranking criterion.

The screen is presented as a way to identify stocks with possible short-term upside, but the article provides no backtest or evidence that the conditions predict returns. It cautions that the approach omits company fundamentals and that inclusion on the attention list may have limited influence on subsequent prices. It recommends considering financial statements, management, industry outlook, and other signals, then validating the combined rules with historical testing before use.

Key ideas

• The proposed screen combines a price-range condition, large-order activity, and prior-day market attention.
• The article treats these inputs as short-term activity and sentiment measures.
• Its code example uses turnover as a stand-in for the stated large-order ranking condition.
• The method does not assess long-term company quality or provide evidence of predictive performance.
• The author recommends adding fundamental information and testing the refined rules historically.
