Chinese Stock Screen for Volatility and Seven Consecutive Declines

Summary

This Chinese-language post outlines a short-term stock-selection screen. It looks for shares with a daily high-low range above 1%, that were not limit-up stocks the previous day, and that have fallen for seven consecutive sessions. The proposed rationale is that active, volatile stocks after a prolonged decline may rebound. The screen is presented as a potential buy signal, with the holding period left to the user.

The post describes technical conditions and includes formula and Python examples intended to implement them, but reports no backtest, returns, or other evidence that the proposed rebound pattern works. It also cautions that the screen ignores company fundamentals and may select weak businesses, while overlooking liquidity and trading risks. Suggested refinements include adding volume, MACD, support levels, moving-average direction, and fundamental data. The examples should be treated as implementation references rather than proof of a reliable edge.

Key ideas

• The screen selects stocks with a daily range above 1%, no limit-up close the prior day, and seven consecutive declining sessions.
• The post interprets the setup as a possible short-term rebound opportunity.
• It leaves the holding period to the user's risk and return preferences.
• The screen omits fundamentals, liquidity, and other sources of trading risk.
• The author suggests adding volume, MACD, support, moving-average trends, and fundamental data for further assessment.
