Screening Chinese Robotics Stocks by Range and Size

Summary

The document presents a Chinese equity screen that selects stocks associated with the robotics concept, with daily amplitude above 1%, circulating market capitalization below 10 billion, and total scale above 200 million. It describes combining these conditions and gives illustrative implementations using a stock screener’s formula language and a Python data workflow. The article characterizes the size floor as a way to focus on relatively larger eligible stocks within the screen.

It offers no backtest, return series, benchmark comparison, or evidence that the criteria predict future performance. The accompanying discussion warns that the size restrictions may exclude high-growth firms, strict filters may remove otherwise suitable companies, and high amplitude brings greater volatility. It suggests adding industry or fundamental measures, relaxing thresholds, and diversifying holdings as possible refinements. The article is therefore a basic screening recipe with generic risk commentary; it does not specify portfolio weights, trade timing, execution, or a tested risk-control process.

Key ideas

• The screen combines robotics-concept membership with an amplitude threshold and market-size limits.
• The article provides examples of implementing the filters with a formula and a Python data workflow.
• The rules may exclude growing companies that do not meet the size requirements.
• The document gives no performance testing and notes that high-amplitude stocks can be volatile.
