Chinese Main Board Screen for High-Range Stocks Rising Over 1%

Summary

This Chinese equity screen filters for main-board stocks outside Beijing, with a daily range above 1% and a daily gain above 1%. The article describes these criteria as a way to focus on volatile stocks with short-term upward movement. It also suggests adding company fundamentals, market capitalization, liquidity, risk-return measures, and capital-flow indicators to broaden the selection process.

The document includes indicator formulas and a Python example, but the exclusion logic is unclear: its prose refers both to excluding Beijing stocks and to excluding non-mainland stocks, while the code’s board and area conditions do not straightforwardly express that description. The code also adds a recent-high filter not present in the stated final rules. No test results or return evidence are given. The article cautions that short-term price conditions can overlook financial health and industry prospects, and that stocks with weak liquidity may carry higher trading risk.

Key ideas

• The stated screen selects main-board stocks outside Beijing with daily amplitude and gain each above 1%.
• The article proposes adding size, liquidity, fundamentals, risk-return, and capital-flow factors.
• The exclusion criteria are ambiguous, and the Python code does not clearly match the written rules.
• The code introduces a recent-high condition absent from the stated final selection logic.
• No performance evidence is reported, and the screen may overlook company and industry fundamentals.
