Screening Robot-Theme Stocks by Range, Float Capitalization, and Control Flow

Summary

This Chinese stock-selection proposal looks for robot-concept shares whose daily high-low range exceeds one percent, whose floating market capitalization is below the stated limit, and which were classified as controlled by large investors on the previous day. The article gives example indicator logic and a Python-style workflow for combining range, theme membership, capitalization, and a large-investor measure. It supplies no backtest, return data, or evidence that these filters predict future performance.

The author cautions that large-investor data may be distorted by low trading activity, unusual early-session moves, and block transactions. Focusing on this measure may also obscure changes in company fundamentals, while broad market conditions can still drive selected shares lower. Suggested improvements include adding technical and fundamental checks, making the filters more stable, and strengthening ongoing risk controls. The formula examples are presented as references requiring adjustment to the chosen data source and strategy; the final fundamental-quality filter is not operationally specified.

Key ideas

• The screen combines a daily range threshold, robot-theme membership, a floating-capitalization ceiling, and a prior-day large-investor control signal.
• The article proposes combining those conditions in indicator logic or a data workflow.
• Large-investor classifications may be unreliable when trading is thin or unusual transactions distort the data.
• The method does not provide backtest evidence or a concrete definition of its fundamental-quality filter.
• Suggested refinements include adding broader technical and fundamental measures and improving risk controls.
