A-Share Screen for High-Amplitude Stocks Outside Beijing

Summary

The document describes a simple Chinese A-share screening rule: select stocks whose high-to-low range exceeds 1%, restrict the data to 2021, and exclude stocks associated with Beijing. It gives example implementations for a charting platform and Python, and characterizes the amplitude filter as a way to find more volatile stocks. The screening conditions are descriptive; the document does not explain how selected stocks would be ranked, entered, or exited.

It offers no performance results or backtest evidence. Its rationale that a historical year identifies stocks that perform well under current market conditions is not supported, and the regional exclusion is also asserted without evidence. The document acknowledges that the screen may perform poorly in weak markets and could omit worthwhile stocks. It suggests adding fundamental or technical filters, setting risk controls, and reviewing the strategy through backtesting, but supplies no detailed validation method.

Key ideas

• The screen selects stocks with a high-to-low price range above 1% in 2021.
• It excludes stocks identified as belonging to Beijing.
• The document gives example implementations in a charting formula and Python.
• It provides no evidence that the screen predicts returns or improves performance.
• It recommends additional analysis, risk controls, and periodic backtesting.
