A Chinese Stock Screen Combining Turnover, Profit Growth, and Consecutive Limit-Ups

Summary

This post presents a China-focused stock selection rule combining turnover, parent-company net profit growth, and recent price-limit behavior. The stated screen seeks stocks with turnover between 3% and 12%, year-over-year profit growth above 20% and no more than 100%, and a three-session limit-up sequence as of the prior day. It also includes example implementations for a Chinese market screening platform and a Python workflow using market and financial data.

The accompanying commentary frames the rule as a mix of fundamental growth and market activity, while warning that the criteria are subjective and that consecutive limit-ups can reflect short-term speculation. It suggests adding valuation or company-size filters and technical indicators. The post does not report a backtest, transaction costs, out-of-sample performance, or risk-adjusted results. Its code examples may not match the prose exactly, so the stated screening logic should be checked against the actual data fields and implementation before use.

Key ideas

• The proposed screen combines a turnover band, a bounded profit-growth range, and a recent three-session limit-up condition.
• The post provides example screening logic and a Python-based data workflow.
• The author notes that strong recent price action may reflect short-term speculation rather than durable fundamentals.
• Additional valuation, size, or technical filters are suggested, but their effect is not evaluated.
• No performance evidence is supplied, and implementation details should be checked against the stated rule.
