A-Share Reversal Screening with Turnover, Float Size, and an Engulfing Pattern

Summary

This A-share screen combines turnover between 3% and 12%, a circulating market capitalization range stated as 1 to 55 billion yuan, and a bullish reversal pattern: the previous session closes below its open, while the current session closes above its open. The article describes this as a short-term price-pattern filter and provides formula and code examples. The title refers to a float-size limit of 5.5 billion shares, but the final rule and examples instead use circulating market capitalization, so the units and criterion are inconsistent.

The document characterizes the strategy as simple and primarily reliant on trading and price data. It offers no backtest or performance evidence. It notes that the screen omits valuation and growth measures and suggests adding indicators such as PE, PB, or PEG, along with moving averages or MACD. Those are possible extensions rather than tested improvements. A stop-loss example appears in the code reference, but the article does not establish a full trading or position-sizing plan.

Key ideas

• The screen combines a 3% to 12% turnover range with a bullish reversal candlestick condition.
• The final rule specifies circulating market capitalization from 1 to 55 billion yuan.
• The title gives a float-share limit, which conflicts with the market-cap criterion in the rule and examples.
• The article offers no performance results and warns that the screen omits valuation and growth factors.
• Valuation measures and additional technical indicators are suggested as possible extensions.
