Screening Chinese A-Shares for Multiple Limit-Up Days

Summary

This proposed Chinese A-share screen selects stocks with at least two limit-up sessions over a 500-day lookback and excludes Beijing-listed shares. The post interprets repeated limit-ups as a sign of strong price action, but provides no backtest results or evidence that this pattern predicts future returns.

The accompanying discussion acknowledges that the rule uses price performance alone and can overlook company finances, industry prospects, valuation, and longer-term behavior. It suggests adding fundamental and quality filters, though it does not specify or test them. The Python example is incomplete: it does not finish the limit-up calculation, and the surrounding text includes a generic selection template. Treat the screen as an unvalidated momentum-style idea rather than a complete, reproducible strategy.

Key ideas

• The screen looks for at least two limit-up sessions within a 500-day period.
• It excludes Beijing-listed A-shares.
• The post presents past price strength as its rationale but supplies no performance evidence.
• Fundamental, industry, valuation, and longer-term factors are identified as potential gaps.
• The code example is incomplete and does not fully implement the stated selection rule.
