Chinese Stock Screening with Moving Average Alignment and Trend Filters

Summary

The document describes a Chinese A-share screening rule combining three moving-average conditions: at least five averages converge, the 20-day average is above the 120-day average, and the 30-day average is rising. It interprets convergence as agreement between shorter and longer trends, while the other conditions seek positive short- and medium-term direction. The suggested workflow adds fundamental analysis after the technical screen.

No backtest, performance figures, or empirical support are provided for the proposed signals. The accompanying code is incomplete, so it does not fully define how to measure average convergence or establish a usable strategy. The document cautions that technical conditions cannot guarantee price gains, and that relying on them alone may overlook company fundamentals. It also identifies frequent trading as a source of higher costs and risk, recommending attention to trading frequency, trade size, and fundamental factors.

Key ideas

• The screen requires at least five moving averages to converge.
• It also requires the 20-day average to exceed the 120-day average and the 30-day average to rise.
• The author presents the conditions as a way to find stocks with positive short-term direction, not as a guarantee of gains.
• The code example is incomplete and does not specify a complete convergence test.
• The document recommends combining the technical screen with fundamental analysis and managing trading frequency and size.
