Screening for Seven Consecutive Declines and 3%–12% Turnover

Summary

This Chinese A-share screen looks for stocks with turnover between 3% and 12% and closing prices lower on each of the previous seven sessions, while excluding companies registered in Beijing. The accompanying formula also applies a registered-capital ceiling and limits the records to the current calendar year. The article includes sample formula and Python logic, though the stated headline conditions and code contain additional universe constraints.

The document describes the screen as a starting point and suggests adding financial measures such as valuation or earnings growth, or technical indicators such as MACD. It gives no backtest, return statistics, or evidence that seven consecutive down sessions predict a rebound or continuation. The rule may sharply narrow the candidate set, and the author flags data reliability as a concern. Implementers should reconcile the prose with the code, especially the added registered-capital and date filters, and verify how the data source defines turnover and consecutive declines.

Key ideas

• The principal filters are 3%–12% turnover, seven consecutive declining closes, and exclusion of Beijing-registered companies.
• The formula adds a registered-capital ceiling and a current-year date condition.
• The document offers no performance evidence for the screen or for the seven-day decline pattern.
• It recommends considering financial and technical measures as additional filters.
• Data definitions and the discrepancy between headline conditions and implementation details require review.
