Main Board Stock Screen Using Turnover, Reversal, and Daily Return

Summary

This Chinese-language post describes a main board stock screen combining turnover between 3% and 12%, a reversal or engulfing-style condition, and a daily return above -5% but below 2.6%. The stated rationale is to find actively traded stocks showing a possible rebound while excluding more extreme daily moves. The post provides sample screening expressions and Python-style calculations, including a range-based measure for the reversal condition, but reports no tested results.

The author notes that the screen relies on technical and trading data without assessing company fundamentals, so candidate quality is uncertain. The simple return bounds may also admit stocks whose short-term moves are unsuitable for longer holding periods. Suggested extensions include valuation, profitability, and moving-average measures. The code should be reviewed before use: its data joins and the operational definition of reversal may not implement the prose description consistently, and no evidence establishes that the setup predicts subsequent gains.

Key ideas

• The screen combines a turnover range, a reversal condition, and bounded daily returns.
• It is intended to focus on actively traded main board stocks with moderate daily moves.
• The post acknowledges that it omits fundamental analysis and may select unsuitable candidates.
• Valuation, profitability, and moving averages are suggested as additional filters.
• No backtest or evidence of predictive performance is provided.
