Screening Robot-Themed Stocks by Volatility, Size, and Limit-Ups

Summary

This Chinese equity screen selects stocks associated with the robotics concept, with daily price amplitude above 1%, circulating market value below 10 billion, and more than two limit-up days within the past 10 days. The article describes these conditions as a way to focus on stocks with recent strong price action and provides example formula and Python approaches for combining the filters.

The source offers no backtest, selection history, or evidence that the criteria predict future returns. It warns that relying on recent limit-ups can neglect longer-term performance, that restrictive conditions may leave few candidates, and that trading can involve chasing prices or selling during declines. It suggests adding fundamental analysis and risk controls or loosening the screen. The examples are illustrative and depend on platform data and implementation details; the document itself advises adapting them to the intended strategy.

Key ideas

• The screen combines a robotics theme, daily amplitude, circulating market value, and recent limit-up frequency.
• It requires more than two limit-up days over a 10-day lookback.
• Recent limit-up activity may emphasize short-term strength while missing longer-term conditions.
• The article provides implementation examples but no evidence of strategy performance.
• It recommends supplementing the screen with fundamentals and risk controls.
