Chinese Stock Screening by Volatility, Recent 龙虎榜 Activity, and Float Size

Summary

The document describes a Chinese stock screening rule combining three conditions: prior-day price amplitude above 1, appearance on the previous day’s 龙虎榜 (a public list of notable trading activity), and a circulating share count no greater than 5.5 billion shares. Its rationale is that larger price swings and recent notable trading may signal short-term interest, while a smaller float may make a stock more responsive to trading flows. It also gives example implementations in two trading environments.

The article warns that small-float stocks may be vulnerable to manipulation and that pursuing short-term gains can involve high risk. It suggests adding technical indicators, company and industry fundamentals, adjusting the float threshold to market conditions, or using machine learning. These are proposals rather than tested improvements: the document supplies no backtest, performance figures, or evidence that the screening rule predicts returns. The interpretation of 龙虎榜 activity as positive sentiment is also an assumption, and the examples do not establish a complete trading or risk-management process.

Key ideas

• The screen combines prior-day amplitude, prior-day 龙虎榜 appearance, and a circulating-share threshold.
• The stated rationale is to seek volatile stocks with recent notable trading and relatively small floats.
• The article flags manipulation exposure and elevated risk in short-term trading of small-float stocks.
• It proposes adding technical, fundamental, industry, or machine-learning inputs, but provides no validation of those additions.
