Screening Chinese A-Shares by Turnover and Institutional Buying

Summary

The proposed stock screen selects shares with turnover between 3% and 12%, excludes Beijing-listed A-shares, and seeks evidence of institutional buying at lower prices. The article frames institutional accumulation as a signal of focused research, while its sample Python implementation adds filters for valuation, revenue, and gross margin. It does not provide a technical indicator formula because the central idea depends on fundamental and institutional information.

The article cautions that institutional buying may not reflect strong or lasting conviction and that the screen omits broader sentiment and volatility conditions. It recommends combining institutional activity with company fundamentals and updating the selection timing and institutional-flow information. There are no backtest results or return data. The code example does not itself identify institutional buying; it filters by turnover and several financial fields, so it only partially represents the stated strategy.

Key ideas

• The stated screen combines a turnover range, a Beijing A-share exclusion, and institutional buying activity.
• The sample code also filters by P/E, revenue, and gross margin.
• Institutional buying can fail to signal durable conviction.
• The article recommends adding fundamental and market-context checks and updating the data over time.
• No evidence of historical performance is provided, and the code does not implement the institutional-buying condition.
