A Seven-Day Decline Screen for Potential Stock Rebounds

Summary

This Chinese stock-screening post proposes selecting shares with daily amplitude above 1, more than one year since listing, and seven consecutive down sessions. The author frames large amplitude as a sign of active trading and the extended decline as a possible oversold condition that could precede a rebound. The post also includes sample Python screening logic, though its implemented checks use a recent price window and price comparisons rather than clearly reproducing every stated criterion.

The strategy is a simple contrarian screen, not a demonstrated trading system: it reports no performance or backtest evidence. The author cautions that fundamentals, valuation, and broader market conditions are omitted, and that a selected stock may continue falling on the next session. Suggested safeguards include adding fundamental and valuation filters and applying stop-loss and position controls.

Key ideas

• The stated screen requires amplitude above 1 and more than one year since listing.
• It also seeks stocks that have fallen for seven consecutive trading sessions.
• The author interprets the sustained decline as a possible oversold signal and rebound opportunity.
• The sample implementation does not clearly match every stated selection condition.
• The post advises adding fundamental and valuation analysis alongside risk and position controls.
