Screening Chinese Stocks by Volatility, Limit-Order-Book Rankings, and Price

Summary

The document proposes a Chinese equity screen that combines prior-session price amplitude above one percent, an appearance on the previous day’s Longhu ranking list, and a current share price below 12 yuan. It shows how to express the three filters using example indicator and Python-style logic, then intersects the qualifying stock sets. The stated rationale is to find volatile stocks receiving notable market attention while applying a low nominal-price cutoff.

The author acknowledges that the screen is simple and can select firms with weak fundamentals; low-priced stocks may remain volatile, attract limited attention, and fail to rise. Suggested refinements include valuation measures, technical indicators, and dividend yield. The document supplies no backtest, risk-adjusted performance, or evidence that the selection criteria predict returns. Its examples also rely on specific data sources and a stated historical lookup date, so implementation requires careful date alignment and validation.

Key ideas

• The screen selects stocks using prior-day amplitude, prior-day Longhu list presence, and a current price ceiling.
• Its rationale combines short-term volatility and market attention with a low nominal share price.
• The author notes risks from weak fundamentals, continued volatility, and limited investor attention.
• Valuation, technical, and dividend measures are suggested as possible additions.
• No performance results are provided to establish that the filters predict gains.
