Screening Chinese Stocks by Range, Limit-Ups, and Position Growth

Summary

This stock screen selects names with a daily high-low range above 1%, at least two limit-up events over the prior 500 days, and a current position-growth measure above 5%. The document presents these conditions as a way to find volatile stocks with prior strong price moves and rising capital interest. It includes indicator and Python examples of the filters.

The material offers no backtest results or evidence that the screen predicts returns. It cautions that the criteria rely heavily on technical and flow-related signals, can capture speculative buying, and omit fundamentals. It suggests combining the screen with company growth, valuation, and broader market sentiment, while treating the resulting candidates as requiring further judgment and adjustment for market conditions.

Key ideas

• The screen requires daily amplitude above 1%, two or more limit-up events within 500 days, and position growth above 5%.
• The author interprets prior limit-ups and rising position growth as signs of volatility and active capital interest.
• The document provides example indicator logic and a Python implementation of the screening conditions.
• It warns that technical and capital-flow filters can expose investors to speculative activity.
• The screen does not establish predictive performance and should be considered alongside fundamentals and market conditions.
