Screening Chinese Stocks for Recent Limit-Ups and Trading Volume

Summary

This note describes a Chinese equity screening rule that combines price movement, trading activity, opening behavior, and recent limit-up frequency. It selects stocks with amplitude above 1, current volume above 10,000 lots, a higher open, and more than two limit-up days in the prior ten days. The accompanying explanation treats these conditions as signs of activity, liquidity, and strong market interest. It also offers a sample implementation using historical stock data, although the code’s precise definitions do not fully mirror every stated screening condition.

The note cautions that the screen omits company fundamentals and capital flows, and may follow speculative market noise. It suggests adding financial and industry measures and applying risk controls. No backtest results, performance evidence, or transaction-cost analysis are provided, so the proposed rule should be understood as a screening idea rather than a validated strategy.

Key ideas

• The screen combines amplitude, current trading volume, opening behavior, and recent limit-up frequency.
• It treats repeated limit-up moves as a sign of strong market attention.
• The sample code uses historical data, but its implementation may not match every stated condition.
• The author warns that the screen excludes fundamental and capital-flow information.
• No performance results or backtest evidence are presented.
