A-Share Screening with Limit-Up Frequency, Volume Strength, and Bollinger Bands

Summary

This A-share screening idea combines a recent surge in limit-up activity with relative trading volume and Bollinger Band position. It selects stocks that ranked among the top 100 by volume ratio, had more than two limit-up days in the prior ten days, and closed between the Bollinger middle and upper bands. The stated rationale is to find names attracting attention while showing short-term price strength without closing above the upper band.

The article proposes refining the screen with upward short- and long-term trend filters, including moving averages and MACD. It gives indicator formulas and illustrative code, but reports no backtest, portfolio returns, or comparison against a benchmark. The source also contains a mismatch: its opening strategy heading refers to price at the upper band, while the detailed conditions place price between the middle and upper bands. It warns that a short-term focus can overlook fundamentals and may not predict future performance; valuation and longer-term trend filters are suggested as possible additions.

Key ideas

• The screen ranks stocks by volume ratio and keeps the top 100.
• It requires more than two limit-up sessions during the previous ten days.
• It places the close between the Bollinger middle and upper bands.
• The article suggests adding upward moving-average and MACD conditions to assess trend.
• It provides no performance evidence and cautions that short-term signals may miss fundamental risks.
