A-Share Screen for Turnover, Small Capitalization, Profitability, and Daily Declines

Summary

The post proposes a rules-based screen for A-shares combining turnover, market capitalization, profitability, and a sharp intraday decline. It selects stocks with turnover between 3% and 12%, market capitalization below 10 billion yuan, no reported loss, and a day’s maximum decline between 4% and 5%. The stated intuition is that such a decline may occur alongside buying that could support a rebound. The article also provides example screening logic and a sample data workflow, but it does not report a backtest or performance results.

The author warns that price movement alone ignores business quality, earnings capacity, competitive position, liquidity, and other risks. The suggested improvement is to assess financial statements and research alongside the price signal. The proposed conditions leave important implementation details unclear, including how “no loss” is defined across reporting periods, how and when positions are entered or exited, and how transaction costs or survivorship bias would affect results. The rebound rationale should therefore be treated as a hypothesis rather than established evidence.

Key ideas

• The screen combines turnover of 3%–12%, capitalization below 10 billion yuan, non-loss status, and a daily maximum decline of 4%–5%.
• The author interprets the decline range as a possible rebound setup, but supplies no performance test to validate it.
• The article recommends combining price signals with company fundamentals and risk assessment.
• Entry timing, exits, costs, and the precise profitability lookback are not fully specified.
