A-Share Screen Using Turnover, Market Capitalization, Profitability, and Ranking-List Activity

Summary

This community post proposes screening A-shares by turnover, market capitalization, profitability, and whether a stock appeared on the previous day’s securities ranking list. The stated criteria are turnover between 3% and 12%, market capitalization below 10 billion yuan, no losses, and prior-day ranking-list appearance. The rationale is to focus on active, smaller companies with positive earnings and notable market attention.

The post warns that ranking-list stocks may experience short-lived popularity and that smaller, high-turnover stocks can be volatile. It suggests supplementing the screen with technical indicators and company fundamentals, but gives no backtest, return evidence, or clear portfolio construction and execution rules. The accompanying formula and Python example do not consistently implement the written logic: the code excludes ranking-list names, and parts of its market capitalization and date checks appear inconsistent with the stated criteria. Treat the proposal as a rough screening idea that requires verification before use.

Key ideas

• The proposed screen combines turnover, market capitalization, profitability, and prior-day ranking-list activity.
• The stated turnover range is 3% to 12%, and the market capitalization cap is 10 billion yuan.
• The post identifies short-term popularity and volatility among smaller, active stocks as risks.
• It recommends combining the screen with technical and fundamental analysis.
• The example code conflicts with the prose about ranking-list inclusion and other screen details.
