Screening Robot-Concept Stocks by Turnover, Float Value, and Control Ratio

Summary

The post proposes screening Chinese stocks for robot-concept membership, turnover between 3% and 12%, circulating market value below 10 billion yuan, and a daily control ratio above 21. The stated idea is to combine thematic exposure and smaller float value with trading activity and a measure intended to indicate concentrated buying or capital inflows. The formula sorts candidates by turnover.

The document warns that the control-ratio condition may exclude attractive stocks and that the screen omits other technical indicators. It recommends reviewing the filter details, potentially loosening thresholds, and adding technical analysis. No backtest, return series, or evidence supports the strategy's effectiveness. The sample Python implementation also diverges from the stated screen: its final turnover range differs, and other filters appear in the code that are absent from the headline rules. Those inconsistencies make the implementation an unreliable reproduction without further checking.

Key ideas

• The stated screen combines robot-concept classification, turnover, float value, and a daily control-ratio threshold.
• The post interprets the control ratio as a measure related to capital inflows.
• The author cautions that the ratio may exclude otherwise attractive stocks and that other technical indicators are omitted.
• No performance evidence or backtest is provided.
• The sample implementation uses filters that conflict with the headline criteria and needs verification.
