Screening Robot-Themed Stocks by Volatility, Size, and Revenue Growth

Summary

This Chinese stock-screening post proposes selecting A-share companies with daily amplitude above 1%, a robotics concept classification, and circulating market capitalization below 10 billion yuan. It also requires revenue in 2021 to exceed revenue in 2018 by more than 10%. The post describes the screen as combining a price movement measure, thematic exposure, company size, and a basic growth test.

It outlines the risks of relying on financial data and revenue growth alone, including data reliability and uncertainty about whether rapid growth can continue. Suggested improvements include reviewing profitability and equity measures, accounting for industry differences, and applying additional technical and financial analysis after the initial screen. The post includes sample formula and Python implementations, but no backtest, performance statistics, or evidence that the criteria predict returns. It should therefore be read as a screening example, with no reported validation and with implementation details requiring careful checking.

Key ideas

• The screen combines daily price amplitude above 1% with a robotics concept classification and a circulating market value below 10 billion yuan.
• It requires 2021 revenue to be more than 1.1 times 2018 revenue.
• The author cautions that revenue growth alone does not establish durable business quality.
• Suggested refinements include profitability and equity measures, industry-aware criteria, and further analysis.
• The post provides example implementations but reports no backtest or return evidence.
