Chinese Stock Screen for Seven Consecutive Daily Declines

Summary

The document describes a Chinese equities screen that combines an amplitude threshold, a limit on the stock’s 9:25 price increase, and seven consecutive sessions of falling closing prices. It presents this as a way to identify stocks undergoing a pullback for possible further review. The article also gives a sample indicator expression and sketches a Python workflow that retrieves market data and filters listed stocks.

The rationale is that a sustained decline may reveal candidates for a rebound or longer-term investment, especially when broad sentiment is weak. However, the document provides no backtest, return figures, or evidence that the conditions predict reversals. It acknowledges that the screen is basic, can miss market and company fundamentals, and may lose effectiveness as conditions change. Its sample implementation also contains apparent inconsistencies with the stated criteria, so the code should not be treated as a verified implementation. The screen is best understood as an initial filter requiring independent validation and risk analysis.

Key ideas

• The screen requires amplitude above one and a 9:25 price gain below six percent.
• It selects stocks whose closing prices have fallen for seven consecutive trading sessions.
• The article frames the decline pattern as a possible pullback signal, but supplies no performance test.
• Company fundamentals, market conditions, and sector themes are suggested as additional screening inputs.
• The sample code may not consistently implement the stated rules and needs validation.
