Screening Chinese Stocks for Turnover and Recent Limit-Up Activity

Summary

This Chinese equity screen selects stocks with turnover between 3% and 12%, codes beginning with 60, and more than two limit-up sessions during a recent ten-day window. The stated rationale is to find actively traded stocks that have shown frequent sharp gains. It also suggests adding company profitability and industry prospects to make the screen less dependent on short-term price action.

The post includes a Python example that filters the stock universe and checks turnover and price-change data. However, the example does not faithfully implement the written rule: its date range spans substantially more than ten days, and its limit-up test accepts two or more qualifying sessions rather than requiring more than two within ten days. It also uses a fixed percentage-change cutoff, which may not capture different listing or price-limit rules. No backtest or outcome data is provided, and the post warns that short-term gains can reflect temporary market themes and randomness. The screen should therefore be treated as a candidate-generation rule, not evidence of a durable edge.

Key ideas

• The stated screen requires turnover from 3% to 12%, a stock code beginning with 60, and more than two limit-up sessions in ten days.
• The rationale is to target active stocks with repeated sharp gains.
• The example code checks a much longer date range and uses a threshold of at least two qualifying sessions.
• The post recommends adding fundamental and industry filters and provides no performance evidence.
