Screening A-Shares for Three Consecutive Down Days

Summary

This A-share screening idea looks for companies with positive earnings, market capitalization below 10 billion yuan, and turnover between 3% and 12%, then selects stocks that have closed below their five-day moving average for three consecutive sessions. The candidates are ranked by market capitalization. The accompanying rationale treats the three-day decline as a possible sign of weak sentiment, while the turnover, size, and earnings filters are intended to narrow the universe.

The article warns that three down days alone can miss important company and industry context and make results unstable. It suggests adding trend or relative-strength indicators and fundamental measures. The example code has material implementation caveats: its turnover thresholds differ from the stated percentage range, its price conditions do not clearly implement three consecutive down closes, and its data requests and earnings calculations may not reliably match the written rules. No backtest, performance evidence, or transaction-cost analysis is provided, so the screen should be treated as a proposed filter rather than a validated strategy.

Key ideas

• The screen combines turnover, market-capitalization, and positive-earnings filters with a three-session price weakness condition.
• Candidates are sorted by market capitalization after screening.
• The article suggests combining price signals with technical and fundamental information.
• The document gives no performance test, and its code does not clearly match all stated screening rules.
