Shenzhen Stock Screening with Turnover, Valuation, and Profitability Filters
Summary
This Chinese A-share screening strategy combines liquidity, size, profitability, and valuation conditions. It selects Shenzhen main-board stocks with turnover between 3% and 12%, market capitalization below 10 billion yuan, no reported losses, price-to-earnings ratios from 0 to 29.01, and price-to-book ratios from 0 to 3.11. The document also provides example implementations for a stock-screening platform and a Python data workflow.
The rationale is to narrow the universe using trading activity and basic financial measures. The document offers no backtest results or evidence that the filters produce superior returns. It warns that financial data can lag price movements and that relying on a small set of valuation measures may omit other important company and industry factors. It suggests adding broader fundamental, industry, and policy considerations, but does not specify how to combine them or test their contribution. The screening conditions therefore describe a candidate-selection method, not a demonstrated investment strategy.
Key ideas
- The screen limits candidates by turnover, market capitalization, reported profitability, and valuation ratios.
- It focuses on stocks listed on the Shenzhen main board.
- The document provides example code but no performance evidence for the selection rules.
- It cautions that lagging financial data and limited fundamental inputs can weaken screening decisions.
- Broader company, industry, and policy factors are suggested as additional considerations.
