A Chinese Stock Screen Using Turnover, Recent Limit-Ups, and Concentration

Summary

This document describes a Chinese equity screening idea that combines turnover between 3% and 12%, at least one limit-up event in the prior 25 days, a concentration condition, and a minimum market-cap filter. Its stated rationale is to find stocks with moderate trading activity and recent price strength, while using concentration as an additional selection criterion. It also offers indicator and Python examples, though their calculations and the written screening description do not map cleanly to one another.

The author cautions that a short-term, price-focused screen can overlook company fundamentals and carry volatility and trading risk. Suggested refinements include adding valuation and profitability measures such as price-to-earnings, price-to-book, and return on equity, as well as reviewing industry outlook and balance-sheet factors. The document supplies no backtest results or evidence that the rules produce stable returns; its claims about potential benefits should therefore be treated as hypotheses for further testing.

Key ideas

• The screen combines a 3%–12% turnover range with a recent limit-up condition and a concentration filter.
• The written rule calls for at least one limit-up event in the previous 25 days.
• The accompanying code examples use filters whose definitions may differ from the prose description.
• The author recommends adding valuation, profitability, and other fundamental measures.
• The document reports no performance test, so the screen’s return and risk characteristics remain unverified.
