Chinese Stock Screening with Trading Range, Listing Age, and Five-Day Average

Summary

This Chinese stock screen combines three filters: daily amplitude above one, more than a year since listing, and a closing price above its five-day moving average. The article presents the moving-average condition as a way to identify a short-term upward trend, while the amplitude threshold seeks stocks with some price activity. Its sample Python logic further narrows the universe to Shanghai-listed shares and compares the latest close with a five-day average; the code expresses the amplitude cutoff as a one-percent return threshold, which may not match every interpretation of amplitude.

The article cautions that the screen omits company fundamentals, industry conditions, and macroeconomic factors, and that a short moving average can lag price changes. It suggests combining additional moving averages or MACD with fundamental filters. No backtest, performance figures, or evidence of profitability is provided, so the screen should be understood as a basic candidate-selection rule rather than a validated strategy.

Key ideas

• The screen requires amplitude above one and a listing history longer than one year.
• It selects stocks whose closing price is above the five-day moving average.
• The sample code additionally limits candidates to Shanghai-listed shares and uses a one-percent amplitude threshold.
• The article notes that the screen omits fundamentals and that moving averages can lag.
• It proposes combining other technical indicators with fundamental filters.
