Stock Screening by Volatility, Smaller Float, and Recent Limit-Up Moves

Summary

This note describes a Chinese equity screen requiring daily amplitude above 1, a circulating share count at or below 5.5 billion shares, and a limit-up move within the past month. It frames these conditions as a way to find volatile, relatively smaller-float stocks that have recently attracted attention. The code examples intersect the conditions and then rank qualifying shares by turnover rate.

The note cautions that recent price action may obscure long-term performance and that a limit-up move can reflect speculation or volatility rather than favorable news. It suggests combining price and volume signals with financial analysis and market context. The document supplies implementation examples but no backtest results or evidence that recent limit-up activity predicts future returns, so the proposed screen remains an unvalidated selection rule.

Key ideas

• The screen combines amplitude above 1 with a circulating share count no greater than 5.5 billion shares.
• It requires a limit-up move during the preceding month and ranks candidates by turnover rate.
• The note treats recent limit-up activity as a possible sign of market attention, not proof of sound fundamentals.
• Recent price moves may distract from long-term performance and may be driven by speculation.
• The document offers no performance results for the screening rule.
