Screening Main-Board A-Shares by Turnover and Daily Gains

Summary

This stock-selection rule screens Chinese equities for turnover between 3% and 12%, excludes stocks associated with Beijing, and selects main-board shares whose daily gain exceeds 1%. The article frames the conditions as a technical screen intended to identify actively traded stocks with positive daily price movement. It includes a formula-style expression and a sample Python workflow using stock listings and daily price data.

The author notes that a single day's rise may not indicate a durable trend or a good entry, and that price action can conflict with broader market or company fundamentals. Suggested improvements include adding indicators such as MACD or RSI, reviewing industry trends, and incorporating financial measures such as revenue and profit. The document does not report a backtest, sample results, or evidence that the filters improve returns. Its code example does not clearly implement the stated turnover range, so the implementation should be checked against the intended screening rule.

Key ideas

• The proposed screen limits turnover to 3%–12%, excludes Beijing stocks, and requires a daily gain above 1% on the main board.
• The rule uses market segment and recent price movement as selection criteria.
• The article warns that a single day's return does not establish a lasting trend or a sound entry.
• It suggests adding technical and fundamental measures for broader evaluation.
• No backtest or performance results are provided, and the sample code may not implement every stated condition.
