Screening Chinese A-Shares by Turnover, Recent Limit-Ups, and Fundamentals

Summary

This stock-selection article describes a screen for shares whose codes begin with 60, whose turnover falls within a specified 3%–12% band, and that recorded at least one limit-up move within the prior 25 days. The initial logic is intended to identify relatively active, attention-grabbing stocks, emphasizing trading activity and market enthusiasm rather than company fundamentals. The post also includes indicator and Python examples for applying related filters to stock data.

It acknowledges that this approach can omit important business and balance-sheet information and can narrow the eligible universe. It proposes adding valuation, profit growth, and asset-quality measures, and broadening the stock universe. However, the final selection logic and code mix the original screen with added filters and contain inconsistent or difficult-to-interpret turnover calculations. No backtest results or validation are supplied, so the screen should be treated as an illustrative selection recipe rather than evidence of a profitable strategy.

Key ideas

• The core screen combines a 3%–12% turnover band, a recent limit-up event, and a stock-code prefix.
• The selection emphasizes trading activity and investor attention rather than fundamentals.
• The article suggests adding valuation, profit-growth, and asset-quality filters.
• The narrower code-based universe can exclude other potentially suitable shares.
• The examples contain inconsistent turnover logic and provide no performance validation.
