Stock Screening with Turnover, Reversal Patterns, and Large-Order Flows

Summary

This selection method screens for stocks with turnover within a specified band, a reversal-style price pattern, and a high rank in large-order net buying. The article describes the flow ranking as a way to incorporate market participation and capital direction. Its formula example further narrows the universe to listed shares on the Shenzhen exchange, while the Python illustration calculates price-range features, joins market-flow and turnover data, and applies the turnover filter.

The document supplies no historical performance test, return statistics, or comparison with a benchmark. It warns that the screen omits company fundamentals and that large-order flow measures may be overly dependent on historical observations or need adjustment for market conditions. The examples also leave implementation details open: a single cited trading date does not show how the screen behaves over time, and the reversal pattern calculation is not fully reconciled with the formula description. Fundamental filters and broader market-flow context are proposed as possible refinements, but their value is not tested.

Key ideas

• The screen combines a bounded turnover range, a reversal-style price condition, and a top-ranked large-order net-buy measure.
• The formula example limits eligible stocks to listed shares on the Shenzhen exchange.
• The code illustrates joining price, flow, and turnover data for a sample date.
• No performance evidence is provided, and the method omits company fundamentals.
• Flow measures and reversal criteria require clear definitions and testing across market conditions.
