Screening Chinese A-Shares by Turnover, Size, Profitability, and Exchange
Summary
The document proposes screening Chinese A-shares for a turnover rate between 3% and 12%, market capitalization below 10 billion yuan, positive net income, and exclusion of Beijing-listed shares. It includes references to a stock selection formula and a Python example using financial statements, listing-market information, and daily valuation data. The stated rationale is to focus on smaller companies that are profitable while filtering out one exchange segment.
The post acknowledges that the screen can miss strong Beijing-listed stocks and does not account for industry differences. It suggests combining the filters with sector, technical, or additional fundamental measures, but provides no backtest, portfolio rules, rebalancing schedule, or performance evidence. The sample code's date windows and market capitalization condition may not cleanly implement every stated criterion, and its selection logic does not clearly apply the turnover range. Treat it as a rough screening example rather than a validated strategy.
Key ideas
- The proposed screen combines a 3%–12% turnover range, a market capitalization ceiling, and positive earnings.
- It excludes Beijing-listed A-shares.
- The document provides formula and Python examples, but the implementation may not match all stated filters.
- It notes that excluding an exchange segment and ignoring industry factors can omit promising stocks.
- No backtest or investment performance evidence is presented.
