Screening Shanghai-Listed Stocks by Turnover and Capital Strength

Summary

This document proposes screening stocks whose codes begin with 60, keeping those with turnover between 3% and 12%, then ranking them by a measure described as capital strength. The commentary presents the ranking as a way to identify actively financed market themes, while warning that the approach gives little attention to industry fundamentals and may suit short-term traders more than long-term investors.

The examples are inconsistent about the ranking variable: the SQL orders by market value, and the Python example retrieves total market value, despite describing the sort as capital strength. The SQL also includes an industry exclusion absent from the stated screen. The document provides no backtest, performance results, or evidence that either turnover or the ranking measure predicts returns. Its main practical lesson is that the criteria and proxy must be defined consistently, and that fundamental and market context may be needed before using such a screen.

Key ideas

• The stated screen selects stocks beginning with 60 and turnover between 3% and 12%.
• It ranks qualifying stocks by a quantity labeled capital strength.
• The sample implementations substitute market value for capital strength, creating a mismatch with the stated logic.
• The commentary warns that the screen may omit industry fundamentals and may fit short-term approaches better than long-term investing.
