A Large-Cap Chinese Stock Screen with Intraday Limit-Up Filtering

Summary

This note outlines a screen for Chinese stocks that combines a minimum daily price range with a large circulating market capitalization and a non-ST status filter. It also aims to avoid stocks that have reached the daily upper price limit during a specified part of the trading day. The article frames these conditions as a way to find active, larger companies with room to rise, and suggests supplementing them with trading volume, price, valuation, and company performance measures.

The post includes indicator formulas and a Python example, but the code does not clearly implement the stated timing condition, so the intended intraday filter should be treated cautiously. It offers no backtest results or evidence that the rules predict returns. The screen also omits other market and company characteristics, and the article itself acknowledges that the selected conditions may miss stocks with strong gains or produce biased selections.

Key ideas

• The proposed screen combines price range, circulating market capitalization, and non-ST status.
• It seeks to exclude stocks that hit the upper price limit during part of the session.
• The article suggests adding volume, valuation, and fundamental measures for further filtering.
• The example code may not match the stated intraday rule, and no performance evidence is reported.
