Screening Shanghai-Listed Stocks with Turnover and a Weekly Moving Average Cross

Summary

This Chinese-language post describes a stock screen that filters for shares whose codes begin with 60, have turnover between 3% and 12%, and whose weekly closing price crosses above its 30-week moving average. The author presents the cross as a possible trend-change signal and provides a Python example that obtains stock data, calculates the moving average, and checks whether the latest close moved above it from at or below the average in the prior week.

The article characterizes the approach as a short-term, high-risk technical screen and warns that it does not assess company fundamentals and may produce volatile results, especially around market reversals. It suggests combining technical signals with company reports, industry information, and other indicators, but supplies no historical test, return figures, or rules for entries, exits, or position sizing. The example therefore illustrates candidate selection rather than a complete or validated trading system; the stated turnover range is part of the screen’s logic, though the sample code does not implement that filter.

Key ideas

• The screen selects stocks with codes beginning with 60 and turnover within a specified range.
• A signal occurs when the weekly close crosses above its 30-week moving average.
• The sample code checks the moving-average cross but does not implement the turnover condition.
• The author warns that the technical screen omits fundamentals and may expose traders to volatile outcomes.
• The post recommends combining technical signals with fundamental analysis but provides no backtest evidence.
