Screening Robot-Concept Stocks by Volatility, Turnover, and Float Size

Summary

This Chinese stock-screening post proposes selecting robot-concept equities using four filters: daily high-low amplitude above a threshold, prior-day trading activity above a stated threshold, membership in the robot theme, and circulating market value below a stated cap. It frames the filters as a way to focus on active, smaller companies that may attract policy or market attention, and includes formula and Python sketches for implementing the screen.

The post provides no historical performance tests or evidence that the selected stocks outperform. It acknowledges that short-term volatility can lead to chasing prices or selling into declines, and that theme and size filters may exclude strong businesses. The implementation examples also contain inconsistencies between the prose and formula units or timing, so the criteria should be checked against the intended data definitions before use. The suggested additions include fundamental measures and further financial-data review.

Key ideas

• The screen combines price amplitude, prior-day trading activity, robot-theme membership, and a circulating market-value ceiling.
• The post presents the filters as a way to find active, smaller thematic equities, but provides no performance validation.
• High volatility and theme-based selection can increase chasing risk and may exclude otherwise attractive firms.
• The code sketches appear inconsistent with some stated units and timing, so the screening definitions require verification.
