Chinese Stock Screening with Fund Flows and Moderate 10-Day Gains

Summary

This stock-screening idea combines three conditions: today’s position-increase ratio must exceed 5%, the product of price change and net large-order flow must be positive, and the stock’s 10-day gain must be above zero but below 35%. The intended signal is a recent upward trend accompanied by supportive capital-flow measures. The document also proposes adding checks on recent financial health and industry prospects.

It provides no backtest, portfolio construction details, or evidence that the screen predicts returns. Its discussion warns that capital flows respond to broader influences and that a positive-trend filter may miss stocks with sharp short-term moves. The sample code is only a rough illustration and does not clearly implement every stated condition, so the screen’s definitions and data handling would need validation before use.

Key ideas

• The screen requires a positive 10-day return below 35%.
• Today’s position-increase ratio must exceed 5%.
• The product of price change and net large-order flow must be positive.
• The document suggests adding financial-health and industry checks.
• No performance evidence is provided, and market-wide influences can undermine the signal.
