A-Share Screen for Volatility, Smaller Floats, and Three Limit-Up Sessions

Summary

This article describes a Chinese equity screen that selects stocks with a prior-day amplitude above one percent, a circulating share count no greater than 5.5 billion, and three consecutive limit-up sessions ending the previous day. The stated rationale is to combine elevated price movement and a comparatively limited share float with strong recent price momentum. Indicator-formula and Python examples are included, and the formula version also mentions ranking candidates by turnover.

The article does not report backtest results or establish that the screen generates positive returns. It acknowledges that repeated limit-up moves may reflect short-term speculation, and that relying on a recent streak can leave the strategy exposed to reversals or overheating. It suggests adding company and industry context, valuation measures, position controls, and stop-loss rules. The coding examples are implementation sketches rather than a verified research process, so their data definitions and consistency would need checking before any strategy evaluation.

Key ideas

• The screen combines prior-day amplitude, circulating share count, and three consecutive limit-up sessions.
• The article presents the screen as a way to find volatile, smaller-float stocks with recent upward momentum.
• One formula example ranks qualifying names by turnover, though no selection performance is reported.
• Limit-up streaks can signal speculative heat and may reverse abruptly.
• The article recommends broader company analysis and explicit risk controls, including position limits and stops.
