Robot-Concept Stocks Screened by Volatility, Size, and Profit Growth

Summary

This Chinese equity screen combines a daily price-range condition with a robot-concept classification, a circulating market value below 10 billion yuan, and parent-company net profit growth above 20% and at most 100% year over year. The write-up presents the conditions as a mix of technical activity, company size, and financial growth. Its illustrative implementation further filters on price-to-earnings ratio and return on equity, then sorts candidates by market value, although those filters are not part of the central stated rule.

The article offers formula and code examples but no backtest or evidence of returns. It notes that one year of profit growth may not show a company’s longer-term prospects, concept stocks may be influenced by market enthusiasm, reported financial data require scrutiny, and a sector-focused screen can concentrate risk. It recommends broader company and industry analysis and risk controls. Some implementation details are inconsistent or unclear, including the market-value units and whether the additional valuation filters are intended as required conditions, so the examples would need validation before use.

Key ideas

• The stated screen requires a price amplitude above 1%, robot-concept membership, and circulating market value below 10 billion yuan.
• It restricts parent-company net profit year-over-year growth to above 20% and no more than 100%.
• The example implementation adds price-to-earnings and return-on-equity filters beyond the core rule.
• The article flags concept-stock sentiment, data quality, and sector concentration as risks.
• No backtest or return evidence is provided, and some implementation units and conditions are ambiguous.
