Screening Chinese Stocks by Turnover, Market Capitalization, and Profitability

Summary

This note describes an A-share screening rule that combines a turnover range, a market-cap ceiling, and a profitability filter. It then applies a second turnover band and, in a sample formula, limits the universe to mainland exchange main boards and stocks with positive price change. The stated aim is to identify actively traded stocks for short- to medium-term speculation.

The article gives selection logic and code references, but no backtest, performance record, or evidence that the filters improve returns. It also flags that turnover alone does not capture company quality or sustainable prospects, and recommends considering financial measures, technical signals, market heat, capital flows, and valuation. The rule is therefore a preliminary screen, not a complete strategy. The code examples should also be checked carefully against the written criteria, since some conditions and data windows do not align cleanly with the prose.

Key ideas

• The screen combines turnover constraints with a market-cap limit and a filter excluding loss-making companies.
• A sample formula also selects main-board stocks with positive price changes.
• The article presents the screen as a way to find short- to medium-term speculative candidates.
• It provides no performance evidence, and turnover does not replace fundamental or broader risk analysis.
