Screening Chinese Stocks by Price Range, Control Activity, and Popularity

Summary

This post describes a short-term Chinese stock screen that first selects shares with an amplitude above 1 and reported main-force control activity on the prior day, then ranks qualifying names by individual stock popularity. It frames the method as a way to combine price movement with market attention and capital activity. The accompanying Python example applies additional filters, including trading activity, turnover, valuation, market-capitalization relationships, shareholder data, and exclusion of special-treatment stocks, before joining a popularity ranking and returning the top result.

The article does not provide a backtest, define the popularity or control metrics in reproducible terms, or show evidence that the ranking predicts returns. It cautions that attention-based selection may encourage trend chasing and does not establish intrinsic value. The example's filters and data sources differ from the brief headline logic, so implementation would require checking field meanings, data quality, and whether the example matches the intended screen. The post recommends adding technical and fundamental information and adjusting conditions to market circumstances.

Key ideas

• The headline screen filters for amplitude above 1 and prior-day main-force control, then ranks stocks by popularity.
• The sample implementation adds turnover, valuation, market capitalization, shareholder, and listing-status filters.
• The post does not define its popularity and control measures or report backtested performance.
• Popularity-based selection can concentrate exposure in current market themes and may promote trend chasing.
