Chinese Stock Screen for Large Swings and Strong Capital Flow

Summary

This Chinese stock-selection proposal combines three filters: a stated amplitude threshold, a prior-day 9:15 matching price at the limit-down level, and ranking by capital strength from high to low. The accompanying explanation interprets large swings as a source of potential opportunities, the early matching price as a clue about market sentiment, and strong capital flow as a way to prioritize stocks attracting funds. It also gives platform-specific formula references and a sample implementation outline.

The note warns that price action and capital strength alone can misrepresent a company’s value, and that fund interest may fade. It suggests adding valuation measures and technical indicators such as KDJ or RSI, followed by individual fundamental review. No backtest methodology or performance evidence is provided, and the formula examples depend on platform-specific fields and data definitions. The screen is therefore a proposal for further research, not evidence of a durable trading edge.

Key ideas

• The screen selects stocks using an amplitude condition, a prior-day 9:15 matching price condition, and capital-strength ranking.
• The author treats the price condition as a possible indicator of market sentiment and capital strength as a measure of investor attention.
• The note cautions that price and flow measures omit company fundamentals and can be misleading.
• It recommends combining the screen with valuation, other technical measures, and individual company analysis.
• The document provides no backtest results to establish the screen’s effectiveness.
