A Chinese Stock Screen Using Turnover, Rising Lows, and Valuation Filters

Summary

This Chinese-language article proposes screening mainland-listed stocks for a turnover rate between 3% and 12%, excluding Beijing-listed shares, and requiring a rising-bottom pattern. Its accompanying Python example adds further filters, including excluding names containing a special-treatment marker, requiring available price-to-earnings and price-to-book data, applying a price-to-earnings ceiling, and selecting stocks whose calculated price change meets a threshold. The example then returns up to twenty candidates.

The article warns that a screen based on a few conditions can miss market sentiment, industry prospects, and company fundamentals, and that the rising-bottom rule needs a clear definition. It recommends adding financial and market measures, adjusting criteria to conditions, and applying risk controls and position sizing. The code and prose do not align cleanly: the example starts from a reverse-pattern list and computes a price-change measure, while the headline strategy emphasizes rising lows. It also uses a dated data snapshot and does not present a backtest or evidence of returns, so the screen should be treated as an illustrative selection idea rather than a validated strategy.

Key ideas

• The stated screen uses a turnover range of 3% to 12%, excludes Beijing shares, and seeks rising price lows.
• The code example adds special-treatment, valuation-data, price-to-earnings, and price-change filters.
• The article recommends incorporating fundamentals, market conditions, and risk controls.
• The prose and code describe somewhat different screening logic, and the example offers no performance validation.
