Screening Chinese Stocks by Range, Market Cap, Profitability, and Trading Activity

Summary

The screen combines daily price range above 1%, market capitalization below 10 billion yuan, positive profits, and appearance on the previous day’s top-trading list. The document presents these conditions as a blend of technical, fundamental, and flow or attention signals. It recommends strengthening the screen with additional technical and financial measures, broader analysis of capital flows, and market sentiment indicators. Its proposed revision also calls for positive net profits in each of the latest four quarters, position limits, and stop-loss controls.

The document gives a stock-selection formula and illustrative Python-like code, but it does not provide backtest results or evidence that the conditions predict returns. It notes that prior-day trading-list data may be limited and that reliance on market attention and capital flows can expose the strategy to sentiment swings. The code examples are references rather than a complete, validated implementation: some added flow and indicator conditions are left unspecified. The screen is therefore a set of candidate filters, not demonstrated investment guidance.

Key ideas

• The initial screen combines a daily range above 1%, market capitalization below 10 billion yuan, profitability, and prior-day trading-list inclusion.
• The proposed revision requires positive net income in each of the latest four quarters.
• The document recommends combining multiple technical, fundamental, capital-flow, and sentiment measures.
• It identifies unreliable trading-list data and sentiment-driven signals as potential risks.
• Position limits and stop-loss controls are suggested, but no performance evidence is supplied.
