A-Share Momentum Screening with Recent Limit-Up Activity

Summary

This stock screen targets Shanghai-listed shares whose prices hit the daily limit more than twice within ten trading days, then ranks candidates by capital strength. The accompanying discussion interprets a Shanghai listing prefix as a proxy for larger or mid-sized companies and repeated limit-up moves as evidence of strong short-term performance. It warns that this emphasis on recent price action may overlook longer-term business value and cannot reliably forecast future returns.

The article’s proposed refinement changes the selection rules: it calls for large circulating market capitalization, a ten-day gain above 20%, price-to-earnings below 20, and a bullish moving-average arrangement. These are presented as screening criteria, not as a tested strategy. The sample code and rule descriptions do not align consistently with the article’s stated initial screen or refinement, and no backtest results or performance evidence are supplied. The suggested additional filters may broaden the analysis, but their effectiveness is not established.

Key ideas

• The initial screen looks for Shanghai-listed shares with more than two limit-up days in ten trading days.
• The article suggests ranking qualifying shares by capital strength.
• Its proposed refinement adds market-capitalization, return, valuation, and moving-average filters.
• The screen may overemphasize short-term performance and provides no evidence of predictive results.
