Screening Low-Priced Robotics Stocks by Amplitude and Market Capitalization

Summary

This document describes a Chinese equity screening rule that selects stocks classified under a robotics concept, with daily amplitude above 1%, circulating market capitalization below 10 billion, and closing price below 12. It explains that the price ceiling is intended to focus the screen on lower-priced shares and gives example logic for combining the criteria. The examples are implementation references rather than a complete trading system.

The author cautions that low-priced, volatile stocks may have weak businesses, financial problems, sharp price moves, or limited liquidity. Suggested refinements include screening for stronger fundamentals, adding technical conditions such as moving averages or volume, limiting position weights, and setting exit levels. The document reports no backtest, performance data, or evidence that the screen predicts returns. Its market-capitalization code example appears to use a threshold that may not match the stated 10-billion limit, so the implementation should be checked against the intended units and data fields.

Key ideas

• The screen combines a robotics concept classification with amplitude, market-capitalization, and price thresholds.
• The stated amplitude condition is greater than 1%, while the price condition is below 12.
• The document identifies liquidity, volatility, and financial quality as risks of low-priced stocks.
• It suggests adding fundamental and technical filters and controlling position sizes.
• No performance test is presented, and the example capitalization threshold should be verified.
