Screening Chinese Stocks by Turnover and Recent Limit-Up Days

Summary

This proposed Chinese A-share screen selects stocks with turnover between 3% and 12%, excludes Beijing-listed shares, and requires more than two limit-up days within a recent ten-day window. The document frames repeated limit-ups as a possible sign of favorable market sentiment and buying interest, while the turnover band is intended to constrain the candidate set. It also suggests considering valuation, dividends, market capitalization, and industry characteristics.

A Python example illustrates a screening workflow, but its implementation does not clearly match the stated rule: it counts limit-up events across the available daily history rather than explicitly restricting the count to ten days, and the shown exchange and code-prefix filters may not fully implement the stated universe. No backtest or return evidence is supplied. The document warns that repeated limit-ups can precede sharp reversals and that relying on this signal alone gives an incomplete assessment.

Key ideas

• The stated screen uses 3%–12% turnover, excludes Beijing-listed stocks, and requires more than two limit-up days in ten days.
• The document treats frequent limit-ups as a possible sentiment and buying-interest signal.
• It recommends considering valuation, dividends, market capitalization, and industry alongside the price action.
• The Python example does not clearly implement the ten-day counting window or the full stated universe.
• No performance evidence is provided, and post-limit-up reversals are a stated risk.
