Screening Chinese Stocks by Turnover, Rising DEA, and Recent Limit-Up-List Appearance

Summary

This Chinese equity screening idea selects stocks with turnover between 3% and 12%, a rising DEA condition, and an appearance on the prior day’s Longhu list, a market activity list. The article frames the Longhu condition as a way to identify stocks attracting speculative attention, combining trading activity and a technical indicator with a recent market event. It provides formula and Python references for implementing the screen, though the displayed implementations do not fully align: the Python excerpt filters turnover and list membership without visibly applying a rising-DEA test.

The author cautions that the screen can be sensitive to market swings and speculation, and that Longhu appearances may reflect trading hype rather than company fundamentals. Suggested improvements include adding other indicators and evaluating candidates from multiple angles. No backtest results, return data, or evidence that the screen predicts future performance are provided, so it should be understood as a candidate-generation rule rather than a validated trading strategy.

Key ideas

• The screen combines turnover in a specified range with a rising DEA condition and prior-day Longhu-list membership.
• The Longhu filter is intended to highlight stocks receiving unusual market attention.
• The Python reference does not visibly implement every condition described in the written rule.
• The author warns that speculative attention and market volatility can dominate fundamentals, and provides no performance validation.
