Combining Price Range, Large-Order Flow, and Company Traits in Stock Screening

Summary

This note describes a Chinese equity screen that combines a price-range condition, large-order net-flow ranking, and a company characteristic. The accompanying examples use prior-day high changes and unusually high volume, then filter companies by a regional or industry label. The stated aim is to find stocks with active trading and potentially stronger business qualities.

The article cautions that the screen omits broad market conditions and macroeconomic factors, and that company classification can be subjective. It recommends adding valuation, growth, financial health, and industry or size context. The examples do not establish that the criteria predict returns: the formula and Python illustration use different conditions, and no backtest or performance evidence is provided. Treat the screen as a rough selection concept requiring consistent definitions and validation.

Key ideas

• The proposed screen combines price movement, large-order net flow, and company characteristics.
• The examples use volume and company classifications as proxies for activity and business context.
• The article flags exposure to market-wide volatility and macroeconomic conditions.
• It recommends adding financial, valuation, growth, industry, and size measures.
• The examples differ in their specific filters and provide no evidence of strategy performance.
