Selecting Chinese Stocks by Turnover, Trading-Volume Imbalance, and Market Capitalization

Summary

The article describes a Chinese stock-selection screen using three conditions: turnover between 3% and 12%, external trading volume more than 1.3 times internal trading volume, and market capitalization of at least 200 million. It provides an SQL-style screening example and a Python reference implementation that evaluate the latest observations for each stock. The screen is presented as a way to combine activity, trading-volume balance, and company size when selecting candidates.

The article does not report backtest results or establish that the filters predict returns. It cautions that market conditions and policy changes may affect selection outcomes, and suggests adding measures of company potential to broaden the screen. There is also a small inconsistency: the title refers to a volume ratio greater than one, while the article’s stated selection logic and examples use a threshold greater than 1.3. The described rules should therefore be checked carefully before implementation.

Key ideas

• The proposed screen selects stocks with turnover from 3% to 12% and market capitalization of at least 200 million.
• It requires external trading volume to exceed internal trading volume by a ratio greater than 1.3 in the detailed rules and examples.
• The article includes SQL-style and Python examples based on each stock’s latest observations.
• Market and policy changes may affect the screen’s results, and no performance evidence is supplied.
• The title’s volume-ratio threshold differs from the threshold in the detailed rules.
