A-Share Screening with Turnover, Market Cap, Profitability, and Control Signals
Summary
The document outlines an A-share stock screen combining a 3%–12% turnover range, a market capitalization below 10 billion yuan, a profitability filter, and a signal described as main-fund control on the previous day. It also provides a sample indicator formula and Python workflow, though the sample’s market-data checks and moving-average conditions do not clearly implement every stated criterion in a consistent way.
The accompanying discussion says that capital-flow signals may help indicate where large investors are active, but warns that they can respond slowly to short-term market changes and do not establish that a stock will rise. It recommends adding financial statement measures, earnings stability, competitiveness, and valuation analysis. No backtest results or performance evidence are presented, so the screen should be treated as a proposed selection approach rather than a validated strategy. Its reliance on an ambiguous control signal and the mismatch between the description and example code are important limits.
Key ideas
- The screen combines turnover between 3% and 12% with a market capitalization below 10 billion yuan.
- It also filters for non-loss-making A-share companies and a previous-day main-fund control signal.
- The document suggests adding financial strength, earnings, competitiveness, and valuation checks.
- Capital-flow signals alone do not guarantee price appreciation and may react slowly to market changes.
