Screening Chinese Stocks by Market Value, Volatility, and Profitability

Summary

This article proposes screening Chinese equities for market value below 10 billion yuan, a volatility condition, and positive profitability over recent years. It describes combining a price range measure with a subjective assessment of company quality and recent net profit, then applying a ranking cutoff. The discussion frames larger price swings as a source of potential opportunity and sustained profitability as a way to exclude loss-making firms.

The article acknowledges that this screen uses limited indicators, can miss promising companies, and may be distorted by volatile market conditions or fluctuating earnings. It suggests adding valuation and growth measures, industry context, and multiple observation periods. Formula and Python examples are supplied, but they do not align perfectly with the prose: the code uses asset and valuation fields in places, while the stated screen emphasizes market capitalization and price amplitude. No backtest results or evidence of profitability are presented, so the criteria are a screening proposal rather than a validated strategy.

Key ideas

• The proposed screen combines a small to mid-sized market capitalization range with a price amplitude filter.
• It seeks companies with positive profits over recent years and a qualitative assessment of business quality.
• The article suggests adding valuation, growth, industry, and broader market measures.
• It warns that earnings fluctuate and that price amplitude may be misleading in unstable markets.
• The examples and prose use some different filters, and no performance evidence is provided.
