A-Share Screen Using Price Range and Capital Flows

Summary

This Chinese stock-selection proposal screens for daily price ranges above 1%, excludes Beijing-listed shares and certain boards, and ranks remaining stocks by capital-flow strength. The article’s later version describes selecting stocks in the upper half of net-flow rankings and adding profitability and valuation filters. It provides formula-style conditions and Python reference logic for applying the screen.

The proposed rationale is that price movement and capital flows can help identify stocks attracting investor activity. The author cautions that the approach neglects company fundamentals and industry conditions, can be vulnerable to manipulated or noisy flow measures, and may miss sector rotation or changing market trends. Suggested improvements include broader financial and industry analysis, trend measures, and risk controls. The sample logic is not fully consistent across sections, and the article supplies no backtest or performance evidence, so the selection criteria should be treated as an illustrative screen rather than a validated strategy.

Key ideas

• The initial screen uses a price-range threshold, regional and board exclusions, and capital-flow strength.
• A later formulation selects stocks ranked in the top half by net capital flow and adds financial filters.
• Capital-flow measures may be noisy or exposed to manipulation.
• The author recommends considering fundamentals, industry trends, and risk controls.
• The document provides no backtest or performance evidence.
