Screening Chinese Robotics Stocks by Turnover and Float Market Value

Summary

The document proposes a Chinese A-share screening rule combining a robotics concept classification, turnover between 3% and 12%, float market value below 10 billion yuan, and exclusion of Beijing-listed shares. It says the exclusion is intended to reduce exposure to policy factors, while warning that it may remove strong companies and leave a smaller set of stocks with less diversification. It suggests relaxing or weighting conditions as possible refinements.

The article includes sample query logic and Python-style implementation guidance, but the examples do not consistently match the stated rule: the code uses different turnover bounds in places, adds a positive-profit screen, and applies exchange filters whose effect is unclear. No backtest, portfolio construction, or performance evidence is provided. The screen is therefore a starting point for research, and its classifications, units, filters, and data joins would need checking before use.

Key ideas

• The proposed screen combines robotics classification, turnover bounds, float market value, and an exchange exclusion.
• The article warns that excluding Beijing-listed shares may shrink the candidate pool and limit diversification.
• It suggests relaxing or weighting filters to avoid overly narrow selection.
• The sample implementation contains conditions that differ from the stated screen.
• No evidence is provided that the selection rules improve returns or control risk.
