Screening Chinese Stocks by Daily Range and Positive Price Movement

Summary

This post describes a simple stock-selection screen based on daily price movement. It keeps shares whose high-to-low range exceeds one percent, excludes names containing a reference to Beijing, and requires the close to be above the open. The post supplies equivalent indicator-style logic and a Python example that ranks qualifying shares by market capitalization up to a chosen holding count.

The accompanying discussion treats the range as a way to find volatile candidates and the positive session as evidence of recent strength. It also acknowledges that relying on these limited historical measures may miss future trend changes, other relevant factors, and risks unrelated to Beijing. The post provides no backtest results or rationale for the geographic exclusion. Its prose refers to returns above zero, while the implementation uses close above open, so the exact meaning of “return” is narrower in the example. The screen is a basic rule set rather than a validated forecasting method.

Key ideas

• The screen requires a daily high-to-low range above one percent.
• It excludes stocks whose names contain a Beijing reference.
• It defines a positive session as a close above the open.
• The example ranks qualifying stocks by market capitalization.
• No backtest supports the filters, and the geographic exclusion is not justified.
