Chinese Stock Screen by Turnover, Exchange, and Opening Gap

Summary

This screening proposal selects Chinese A-shares with turnover between 3% and 12%, excludes Beijing-listed shares, and requires the 9:25 indicated gain to be below 6%. It presents turnover as a way to target trading activity and liquidity while avoiding a large opening move. The accompanying discussion suggests that the filters may help identify candidates, but says that screening only on market activity and price movement omits other drivers of returns.

The post recommends adding fundamental and technical measures, such as valuation ratios and moving-average or MACD signals, and cautions that the chosen observation time and thresholds can affect results. It includes sample indicator and Python snippets, but they do not establish a tested strategy, and parts of the implementation appear inconsistent with the stated rules. No backtest or outcome data are reported, so the screen's predictive value remains unverified.

Key ideas

• The screen uses a 3%–12% turnover band and excludes Beijing-listed shares.
• It limits the indicated 9:25 gain to less than 6%.
• The author identifies omitted fundamental and technical factors as a limitation.
• No backtest results are provided, and the sample implementation does not fully validate the stated screen.
