Screening Chinese Robot-Concept Stocks by Age, Amplitude, and Float Value

Summary

This stock-selection outline screens Chinese equities for a daily price amplitude above 1, a listing history longer than one year, membership in a robotics concept group, and circulating market value below 10 billion yuan. It describes joining listed-company and concept data, then applying a market-value threshold. The article frames the result as a focused small-float robotics watchlist, rather than providing a complete ranking or trading system.

The evidence is descriptive: the document supplies selection criteria and a code sketch, but no historical returns, benchmark comparison, or validation of the screen. It notes that concept classifications and the market-value cutoff require periodic review. Smaller-cap stocks can carry greater risk, and robotics exposure or a low float value does not establish future performance. The example also leaves subsequent stock selection unfinished, so practical implementation requires checking data definitions and completing the decision rules.

Key ideas

• The screen requires more than one year of listing history and daily amplitude above 1.
• It narrows the universe to stocks tagged with a robotics concept classification.
• It sets a circulating market-value ceiling of 10 billion yuan.
• The document warns that concept labels and thresholds may need revision and that smaller stocks can be riskier.
• The code example does not complete a final selection or provide backtest results.
