Screening A-Shares by Volatility, Large-Order Flow, and Stock Attention

Summary

This article outlines a short-term stock selection approach based on price amplitude, rankings by large-order net flow, and sorting by individual stock attention. It frames these features as ways to find actively traded shares where market sentiment and price fluctuations may create short-lived opportunities. The examples refer to volume and turnover conditions as additional technical and flow filters, then propose selecting a limited number of candidates.

The document cautions that this approach gives little weight to fundamentals and that current popularity may not predict future returns. It recommends considering company valuation, dividends, market capitalization, and longer-term price trends, as well as incorporating more than one ranking factor. The accompanying code and indicator example are illustrative and do not establish a robust or fully consistent implementation of the stated ranking logic. No historical test, transaction-cost analysis, or measured performance is provided, so the method should be treated as a screening idea rather than evidence of an exploitable edge.

Key ideas

• The proposed screen combines price amplitude, large-order net flow rankings, and stock attention.
• The article presents the method as a way to identify short-term activity and sentiment shifts.
• It warns that popularity rankings can change and do not guarantee future performance.
• Fundamental measures and longer-term price trends are suggested as complementary selection inputs.
• The examples provide no backtest or evidence that the screen is profitable.
