Screening Robotics Stocks by Amplitude, Control, and Float Value

Summary

This note describes a Chinese A-share screen for robotics concept stocks. It requires daily amplitude above 1, a signal labeled as main-force control on the prior day, and circulating market capitalization below 10 billion yuan. Its indicator references approximate amplitude with a market-data field and main-force control with the close relative to a five-day moving average; the accompanying example also applies a positive price-to-earnings filter.

The rationale is to combine volatility, perceived capital interest, sector membership, and a smaller float value. The document does not provide backtest results or evidence that these conditions predict returns, and its explanatory claims about upside potential are not substantiated. It flags subjectivity in defining the robotics concept and the possibility that a single capitalization threshold excludes suitable stocks. It suggests refining industry classification and adding measures such as volume, RSI, valuation, or alternative capitalization limits, but does not test those changes.

Key ideas

• The screen combines robotics concept membership with amplitude above 1 and prior-day main-force control.
• Circulating market capitalization must be below 10 billion yuan.
• The code references approximate control with price relative to a five-day moving average and also filters for positive earnings multiples.
• Concept classification and a single size cutoff may make the selection incomplete or inconsistent.
• The note offers no performance evidence for the screen.
