A Turnover and Ownership Screen for Chinese A-Shares

Summary

This proposed Chinese A-share screen selects stocks with turnover between 3% and 12%, excludes Beijing-listed or Beijing-based names, and uses enterprise ownership or company classification as an additional selection dimension. The accompanying discussion suggests combining that classification with fundamental and technical measures because ownership type alone cannot capture a company’s prospects or risks, and classification rules may not fit every firm. The document gives no backtest, return series, or evidence that the turnover band or geographic exclusion improves performance. Its illustrative code also appears to implement a revenue-ratio condition and geographic filter rather than the stated turnover range and enterprise-type logic, so it does not fully specify a reproducible strategy. Treat the screen as a rough idea requiring precise data definitions, validation, and risk analysis.

Key ideas

• The proposed screen combines a turnover band with a Beijing exclusion and an enterprise-classification criterion.
• The text recommends adding fundamental and technical measures to avoid relying on company classification alone.
• Classification accuracy depends on the chosen definitions and may not suit unusual firms.
• No performance evidence is supplied, and the code example does not match the full stated selection logic.
