Screening Chinese Stocks by Range, Turnover, and Recent Limit-Up Events

Summary

This screening idea selects stocks with a large price range, prior-day actual turnover between 3% and 28%, and at least one limit-up event in the preceding 25 days. The article presents these filters as a way to identify active shares that have recently shown strong price movement. It includes illustrative formula and data-processing examples, but supplies no backtest or evidence that the conditions predict future returns.

The stated risks are that past limit-up behavior may not persist, current price action is not considered directly, and the screen may miss financial or business factors. The article recommends adding financial measures and monitoring current market conditions. Its examples leave potential implementation ambiguities, including how the range threshold is scaled and how the prior-day turnover filter aligns with the data fields, so the specification would need checking before use.

Key ideas

• The screen requires a large price range and prior-day turnover between 3% and 28%.
• It also requires at least one limit-up event during the prior 25 trading days.
• The rationale relies on activity and recent strong price action, without reported performance evidence.
• Past limit-up events may not reflect current conditions, and the examples need implementation checks.
