Screening Shenzhen Main Board Stocks with Turnover, Order Flow, and Valuation

Summary

This document describes an equity screening rule for Shenzhen main-board stocks. It combines a turnover range, a condition that displayed first-level bid volume exceeds ask volume, and positive price-to-earnings and price-to-book ratios below stated ceilings. Candidates are ranked by price-to-earnings ratio, with the stated selection rule taking the first 50. The page also includes sample query and Python snippets as implementation references.

Key ideas

• The screen combines trading activity, displayed order-book imbalance, and valuation filters.
• Candidates are restricted to Shenzhen main-board stocks with positive price-to-earnings and price-to-book ratios under the stated limits.
• The proposed ranking selects stocks with lower price-to-earnings ratios first.
• The document warns that valuation multiples alone omit factors such as growth, cash flow, and industry conditions.
• The sample code and described rule are not fully consistent, so implementation details require checking.
