Chinese Stock Screen Using Daily Range, Limit-Ups, and the Ten-Day Average

Summary

This stock-selection idea combines three daily-chart conditions: a price range above a stated threshold, at least two limit-up events during the prior 500 days, and an opening price near the ten-day moving average. The article frames range and limit-up history as signs of market activity or sentiment, while proximity to the moving average is intended to retain stocks aligned with a short-term trend. It includes formula examples and sample Python-like filtering logic, but does not report a backtest, returns, or a defined portfolio construction process.

The author cautions that range and limit-up counts are short-term features that may behave differently across market conditions and time periods. The opening-price proximity rule may also fit stocks unevenly, and the screen omits company fundamentals. Suggested extensions include adding valuation measures and adapting rules to sectors or market themes. Implementation details in the examples may require adjustment to the data source and market conventions before use.

Key ideas

• The screen requires a sufficiently large daily range, repeated limit-up events, and an opening price near the ten-day average.
• The article interprets range and limit-up history as activity or sentiment signals and the moving average as a trend filter.
• It gives formula and sample filtering references but no performance evaluation.
• The approach omits fundamentals and may be sensitive to market regime and stock-specific behavior.
• The author suggests combining short-term conditions with longer-term measures or sector-specific rules.
