Screening Shenzhen Robot Stocks by Range, Size, and Valuation

Summary

The document outlines a China A-share stock screen combining a daily amplitude threshold, membership in a robotics concept group, a circulating market-cap ceiling, and positive valuation ratios below specified upper bounds. It describes the screen as targeting Shenzhen main-board stocks and gives example formula and Python-style implementation steps for combining price, concept, capitalization, and financial data conditions.

The text recommends adding company and industry fundamentals, combining other selection signals, and relaxing overly strict filters where appropriate. It warns that valuation screens can exclude fast-growing firms or capture weak companies that appear cheap. The page offers no historical universe definition, point-in-time data treatment, transaction costs, portfolio rules, or backtest results. There is also a mismatch between the title's stated P/E range and the body and examples, which specify a wider upper limit; the intended threshold should be verified before implementation.

Key ideas

• The screen combines price amplitude, robotics classification, market capitalization, and valuation filters.
• The examples use price and financial data to implement the combined conditions.
• The document cautions that strict valuation filters may miss growth companies or select risky low-valued firms.
• The title and the detailed criteria state different P/E upper bounds, so the intended value needs checking.
