Screening Chinese Stocks by Range, Large-Order Flow, Market Cap, and Profitability

Summary

This note describes a Chinese equity screen combining daily price range, large-order net flow ranking, a market-cap ceiling, and positive earnings. Its stated aim is to identify smaller companies with market activity while retaining a basic profitability filter. The accompanying indicator formula also checks trading amount and limits the decline in the low price over a lookback period. A Python example adds turnover, return-on-equity, earnings, listing-age, and price-history checks.

The document gives no backtest, portfolio construction rules, or performance evidence. Its explanations are qualitative: it argues that combining technical and fundamental filters may help find medium- to long-term opportunities, while warning that falling or sideways markets may challenge the screen and that a market-cap cap excludes larger firms. The formula, prose, and sample code do not align perfectly on their thresholds or definitions, so the screen would need careful data-field validation and testing before use. The article itself recommends adapting conditions to market changes and checking feasibility through backtesting.

Key ideas

• The proposed screen combines price amplitude, large-order net flow ranking, a market-cap limit, and positive earnings.
• The indicator formula also filters on trading amount and a bounded decline in lows over a lookback window.
• The Python example adds turnover and profitability checks, but its criteria differ from parts of the prose.
• The article identifies weak adaptation in falling or sideways markets and missed opportunities from a size cap as risks.
• It provides no measured returns or backtest evidence, so the method's effectiveness is unestablished.
