Screening Robot-Theme Equities by Amplitude, Market Value, and Daily Return

Summary

The document describes a Chinese equity screen for robot-themed stocks with daily price amplitude above 1%, circulating market value below 10 billion, and daily return between -5% and 2.6%. It outlines formula-style and Python examples for applying the concept filter, calculating amplitude and return, and combining the conditions into a candidate list.

The author warns that the screen uses few variables, can select volatile stocks, and may perform poorly during broad or industry downturns. Suggested refinements include adding financial measures, industry context, market trends, and weights across several indicators. No backtest, benchmark, or performance results are supplied, and the code examples may require adaptation to the data provider and units used. The screen is therefore a preliminary selection rule, not evidence of investment value or a complete trading system.

Key ideas

• The screen selects robot-concept equities using amplitude, market value, and daily-return thresholds.
• The examples combine price calculations with a concept-membership filter.
• A small set of technical and size conditions can leave important company and market risks unmeasured.
• The document recommends adding financial, industry, and trend information, but reports no tested results.
