A Chinese Stock Screen for Turnover and Seven-Day Declines

Summary

This Chinese-language strategy note proposes screening stocks with turnover between 3% and 12% after seven consecutive declining sessions, while excluding selected board classifications. It frames the screen as a possible way to find established companies undergoing extended pullbacks that might rebound. The article also supplies example formula and Python implementations, although the formula's conditions do not transparently match every element of the stated screening logic.

The document offers no backtest results, entry or exit rules, holding period, or portfolio construction details, so it does not establish that the proposed rebound premise is profitable. It cautions that technical filters can overlook fundamentals and that excluding a market segment may remove exposure to emerging industries. It recommends combining technical signals with company fundamentals and other measures such as industry conditions and valuation, but provides no evidence for those proposed additions.

Key ideas

• The screen selects for turnover from 3% to 12% and seven consecutive down sessions.

• The author suggests that a prolonged decline could precede a rebound, but supplies no performance evidence.
• The article warns that technical filters can miss fundamental risks and recommends adding broader company analysis.
• The example implementations may not fully align with the described screening conditions.
