Weekly Trend Screen Using a 30-Week Moving Average

Summary

This article describes a stock screen that requires price amplitude above 1, a listing history longer than one year, and a weekly indicator crossing above its 30-week moving average. It argues that weekly data can reduce the influence of short-term fluctuations and treats an upward cross as a favorable trend signal. The article includes an indicator formula and a Python example focused on listed Chinese shares.

The screen uses volatility, listing age, and a moving-average trend condition; it does not specify how to enter, size, or exit positions. The article cautions that it omits fundamentals, broader market conditions, and sector rotation, and notes that volatile stocks can carry substantial price risk. It suggests adding other technical measures and risk controls. No historical results are reported, and the accompanying Python example checks whether the latest close is above the moving average rather than explicitly verifying that a crossover occurred on that date.

Key ideas

• The proposed screen combines amplitude above 1, more than one year since listing, and a weekly crossing above the 30-week average.
• Weekly observations are intended to reduce the influence of shorter-term price moves.
• The article describes the crossing as a trend signal but provides no performance evidence.
• Fundamentals, market conditions, sector rotation, and risk controls are outside the basic screen.
• The Python illustration tests the latest close against the moving average rather than confirming a fresh crossover.
