Screening Shanghai-Listed Stocks by Amplitude and 250-Day Trend

Summary

This Chinese equity screen selects stocks whose codes begin with 60, whose daily high-low amplitude exceeds 1%, and whose prior closing price is above the 250-day moving average. The document interprets the amplitude filter as a way to focus on more volatile shares and the long moving-average condition as evidence of an upward price trend. It also warns that a single technical signal can produce false positives and that high-amplitude stocks carry greater risk.

The article provides example indicator and Python selection logic, and recommends combining technical conditions with financial measures, fundamentals, or other indicators. It reports no backtest, returns, or risk statistics, and gives no entry, exit, sizing, or execution rules. The screen is therefore a candidate-selection rule rather than a complete or empirically validated trading strategy.

Key ideas

• The screen requires daily high-low amplitude above 1%.
• It restricts candidates to stocks with codes beginning with 60.
• A prior close above the 250-day moving average is used as a trend filter.
• The article warns of false signals and elevated risk in volatile stocks.
• It presents no performance evidence or full trading rules.
