A-Share Screen Using Turnover, Profitability, Market Cap, and Opening Gain

Summary

The document describes a short-term A-share stock screen combining turnover, market capitalization, profitability, and the price move observed at the market open. It selects shares with turnover between 3% and 12%, market value below 10 billion yuan, no reported losses, and an opening gain below 6%. The proposed selection is then ordered by opening gain. The article also provides example implementation references, though the sample code uses historical date ranges and data fields that may not represent a live, point-in-time process.

The rationale is that liquidity, smaller capitalization, positive earnings, and a modest opening move may identify candidates for short-term trading. The author cautions that the screen omits deeper fundamentals and that intraday conditions can change after the opening. Suggested extensions include financial ratios, technical indicators, and market or sector context. No backtest results or evidence of profitability are presented, so the screen should be treated as a hypothesis rather than a validated strategy.

Key ideas

• The screen combines turnover of 3% to 12%, market value below 10 billion yuan, and nonnegative profitability.
• It selects stocks whose observed 9:25 opening gain is below 6% and ranks candidates by that gain.
• The article frames the method as suitable for short-term stock selection but provides no performance evidence.
• Intraday changes, market flows, and limited fundamental analysis are identified as risks.
• Possible additions include valuation, earnings measures, technical indicators, and sector context.
