A-Share Screen Using Positive MACD, Positive P/E, and Limit-Down Auction Price

Summary

This A-share screening rule combines three conditions: MACD above zero, a positive price-to-earnings ratio, and a prior-day 9:15 matching price at or below the referenced limit price. The document interprets positive MACD as an upward trend cue, positive P/E as a basic valuation filter, and the auction-price condition as a possible sign of accumulation. It also describes ranking qualifying stocks by turnover rate and gives formula and Python examples.

The article cautions that the selected stocks may lack growth or earnings quality and that screening errors are possible. It provides no backtest results, evidence for the accumulation interpretation, or detailed trading and risk-management rules. The code examples depend on accurate, consistently defined historical auction and limit-price data, and the written and coded conditions should be checked for timing alignment before testing. This is best treated as an exploratory screen requiring validation, not as a complete strategy.

Key ideas

• The screen requires positive MACD, positive trailing P/E, and a prior-day auction-price condition relative to the limit price.
• The article interprets the conditions as trend, valuation, and possible accumulation signals.
• Qualifying stocks are proposed to be ranked by turnover rate.
• No performance evidence is presented, and data timing and metric definitions require verification.
