Screening Shenzhen Main Board Stocks by Turnover, Limit-Ups, and Valuation

Summary

This post describes a Chinese A-share stock screen combining turnover, recent limit-up activity, exchange segment, and valuation. It seeks Shenzhen Main Board stocks with turnover between 3% and 12%, at least one limit-up in the prior 25 days, PE from 0 to 29.01, and PB from 0 to 3.11. The article also shows a formula and a Python-style example for assembling the filter.

The author frames the criteria as a way to find potentially undervalued stocks, but provides no backtest, performance data, or evidence that the screen predicts returns. It cautions that valuation multiples omit other drivers such as industry conditions and company fundamentals, and that combining strict thresholds may leave few candidates. Suggested extensions include dividend yield, technical signals, and sector trends. The Python example’s data handling and proxy conditions may not exactly match the stated screening logic, so the article is best read as a screening concept rather than a validated strategy.

Key ideas

• The screen combines a 3%–12% turnover range with at least one limit-up in the previous 25 days.
• It restricts candidates to Shenzhen Main Board stocks with PE from 0 to 29.01 and PB from 0 to 3.11.
• The article presents valuation and limit-up activity as candidate filters, without performance evidence.
• Industry, fundamentals, and market conditions may materially affect results.
