Screening Chinese A-Shares by Turnover and the 250-Day Moving Average

Summary

This stock screen selects Chinese A-shares with turnover between 3% and 12%, excludes Beijing-listed shares, and requires the prior day's price to be above its 250-day moving average. The rule combines a liquidity or activity range with a long-term trend filter, aiming to find shares showing positive price behavior. The document also gives a formula reference and a Python example for retrieving stock data and checking the moving-average condition.

The page provides no backtest, performance statistics, benchmark comparison, or evidence that the selected stocks continue to rise. It cautions that the screen relies on technical criteria and omits company fundamentals and industry conditions; it may also select shares near highs or amid unclear trends. Suggested refinements include adding fundamental measures and combining turnover with market capitalization. The code example should be treated as illustrative: the text does not explain data availability or validate that its fields and comparisons are correct.

Key ideas

• The screen requires turnover within a 3% to 12% range and excludes Beijing A-shares.
• It selects shares whose prior-day close is above the 250-day moving average.
• The rule uses activity and trend conditions but does not incorporate company fundamentals or industry context.
• The document suggests adding fundamental measures and market capitalization as possible refinements.
• It reports no backtest or performance evidence for the screening rule.
