Screening A-Shares by Turnover, Market Value, Profitability, and Listing Age

Summary

This proposed A-share screen filters for stocks with turnover between 3% and 12%, market value below 10 billion yuan, no reported losses, and a listing history beyond a stated minimum such as three years. The stated rationale is that an established trading and listing history may help identify relatively stable firms. The article presents sample selection logic and a Python illustration that queries stock, income, and daily market data.

No historical backtest or return evidence is provided. The author acknowledges that turnover, size, profitability status, and listing age do not capture a company’s overall operations, earnings quality, competitive position, or future prospects, and recommends combining these filters with broader financial and industry analysis. The example code uses specific historical date ranges and data conditions, so it would need adaptation before use; the screen is an initial candidate filter, not evidence of investment quality or low risk.

Key ideas

• The proposed universe is A-shares meeting turnover, market value, profitability, and minimum listing-age criteria.
• The article presents a rationale based on selecting firms with an established history but supplies no performance evaluation.
• The author recommends adding analysis of operations, earnings, competitiveness, and industry prospects.
• The sample code relies on particular data dates and requires adjustment for current screening use.
