Screening for Recent Limit-Ups and Clustered Moving Averages

Summary

This Chinese equities screen combines three conditions: daily amplitude above 1, at least one limit-up event within the previous 25 days, and price lying within a stated tolerance of five moving averages based on different lookback periods. The article provides example indicator logic and a Python outline that calculates the rolling limit-up count and moving averages, then retains stocks satisfying the combined conditions.

The proposed interpretation is that recent limit-up activity may reflect positive market attention, while proximity to several averages indicates price consolidation or alignment. These are screening rationales rather than demonstrated effects. The article reports no backtest or return evidence and notes that historical patterns may not predict future results, moving-average clustering does not prevent sudden price moves, and short-term volatility creates adjustment risk. It suggests validating with other indicators and fundamentals, while taking account of transaction costs and risk controls. The supplied code and thresholds may need review for data definitions and implementation details.

Key ideas

• Candidates must have amplitude above 1 and at least one qualifying limit-up event during the prior 25 days.
• The screen also requires price to remain within the stated tolerance of five moving averages.
• The article treats recent limit-up activity as a possible sign of market interest, not proof of future performance.
• It identifies sudden price moves, historical-data limitations, and short-term volatility as risks.
• The example code illustrates a screen and does not report tested trading results.
