A-Share Screen Combining Recent Limit-Ups, Price Range, and Company Type

Summary

This proposed A-share stock screen combines a price-range condition, three consecutive daily limit-up moves ending the previous day, and a company-type filter. Its rationale is that larger price movement may indicate active trading and repeated limit-ups may reflect strong buying interest. The article suggests that company characteristics could help identify firms with favorable prospects, then proposes adding financial data and broader industry and market conditions to improve the selection process.

The article describes risks including reliance on short-term sentiment, company type being difficult to quantify, and omission of sector-wide or market-wide adjusted price behavior. Its example code is only a sketch: the company-data condition is left as a placeholder, and the cited price-change thresholds may not fit all securities or market rules. No backtest, portfolio results, or evidence of predictive value is provided, so the screen should be treated as an incomplete hypothesis rather than a validated strategy.

Key ideas

• The screen combines price amplitude, three prior consecutive limit-up sessions, and company characteristics.
• The article interprets repeated limit-ups as a possible sign of strong buying interest.
• It recommends adding financial data and industry or market context to the selection process.
• The code leaves the company-data filter unfinished and provides no performance evidence.
