Screening Chinese Robot Stocks by Volatility, Size, and Recent Limit Ups

Summary

This stock screen combines three conditions: daily amplitude above 1%, membership in the robotics concept group, and circulating market capitalization below 10 billion yuan. It also looks for a limit-up event within the previous 25 days, using recent price action as a signal that the stock may have short-term momentum. The article presents the rules as a selection strategy and includes illustrative indicator and Python snippets, along with heat-based ranking.

The document offers no historical returns, benchmark comparison, or out-of-sample evidence, so it does not establish that the screen is profitable. It cautions that technical filters can miss company financial and operating risks, and suggests adding fundamental measures or other indicators such as MACD or RSI. The example implementations also leave details of signal timing and the exact lookback calculation unclear, which would need to be resolved before reliable testing or live use.

Key ideas

• The screen selects stocks with amplitude above 1% and circulating market capitalization below 10 billion yuan.
• Candidates must belong to the robotics concept group and have had a limit-up event within the prior 25 days.
• The article treats recent limit-up activity as a possible short-term opportunity signal but provides no performance evidence.
• It recommends considering company fundamentals and additional technical indicators to broaden the screening process.
• Signal timing and some implementation details require clarification before backtesting.
