A-Share Screen for Turnover, Market Cap, Profitability, and Limit-Ups

Summary

The article outlines an A-share stock selection screen combining turnover, company size, profitability, and past price-limit events. It selects shares with turnover between 3% and 12%, market capitalization below 10 billion yuan, no reported loss, and at least two limit-up events within 500 days. It provides an example screening formula and a Python-style workflow that retrieves stock, income, daily basic, and price-limit data before adding qualifying symbols to a list.

The author notes that the screen emphasizes trading activity and price behavior while giving limited attention to company fundamentals. Suggested refinements include examining financial statements, cash flow, earnings stability, competitiveness, and valuation. No backtest, benchmark, or performance results are presented, and the sample data queries use fixed date ranges that may not match the stated rolling horizon. Limit-up history and coarse profitability checks alone do not establish future returns or capture company-specific risk.
