Screening Robot-Themed Small Caps by Turnover and Relative Volume

Summary

This Chinese A-share screening idea selects robot-concept stocks with circulating market value below 10 billion yuan, turnover between 3% and 12%, and a volume ratio above 1.5 but below 6. The stated rationale is to focus on robot-related small caps with elevated, but bounded, trading activity. The page also says to rank qualifying stocks by turnover.

The article flags that the screen relies heavily on volume ratio and omits other relevant measures, such as dividends and financial condition. It recommends adding valuation and fundamental criteria and adapting the rules to market conditions. A Python example is included, but it does not cleanly match the headline criteria: it uses different turnover and return filters, and its implementation of volume ratio is questionable. No backtest results or performance evidence are provided, so the screen is a selection recipe rather than a validated trading strategy.

Key ideas

• The screen combines a robot-concept classification with a circulating market value ceiling and turnover and volume-ratio bounds.
• The stated turnover range is 3% to 12%, while the volume ratio must be above 1.5 and below 6.
• The article proposes ranking qualifying stocks by turnover.
• The screen omits financial and valuation checks, which may leave relevant risks unexamined.
• The accompanying Python example diverges from the stated criteria, and the document gives no performance results.
