A Chinese Stock Screen Combining Seven Down Days and Trading Signals

Summary

This stock-selection idea combines three conditions: daily price amplitude above 1, an indication of large-investor control on the previous day, and seven consecutive down days. It adds a daily trading-volume threshold above 3 million shares. The rationale is to find volatile stocks showing signs of institutional activity after a sustained decline, with the possibility of a rebound. The document does not provide backtest results or evidence that the signals predict returns.

The author flags the risk of overemphasizing short-term rebounds while overlooking company fundamentals and longer-term trends. Suggested refinements include adding indicators such as MACD, KDJ, or RSI and reviewing fundamentals. The accompanying code is presented as a reference, but its implementation details and data fields are not fully explained, so the stated screening logic may not be reproducible as written. The idea should be treated as a hypothesis requiring validation, including out-of-sample testing and attention to transaction costs.

Key ideas

• The screen looks for stocks with amplitude above 1 and seven consecutive down days.
• It also requires a signal described as large-investor control on the previous day.
• The final selection adds daily volume above 3 million shares.
• The document suggests combining technical signals with fundamental analysis.
• No performance evidence is supplied, and the code may not fully implement the stated conditions.
