Chinese Stock Screen Using Auction Net Buying and Recent Position Growth

Summary

This proposed Chinese stock screen combines three signals: today’s position-growth share above 5%, positive net buying attributed to major participants during the auction, and a reference to performance in 2021. The article interprets position growth and auction buying as signs of favorable investor expectations. Its discussion of the historical-year condition is unclear: it describes strong performance in 2021 as desirable, but the final selection logic does not specify a measurable performance threshold.

The post also suggests adding valuation filters, moving-average alignment, and a MACD signal. Its Python example sketches calculations for price-to-earnings and price-to-book ratios and trend indicators, but contains inconsistent or incomplete field references, so it does not establish a reproducible implementation. No backtest or performance evidence is supplied. The author warns that crowded expectations or heavy buying could precede sharp short-term moves, and that past performance may not persist. The screen is therefore best understood as an informal set of proposed filters rather than a validated trading method.

Key ideas

• The proposed screen uses position growth above 5% and positive net buying during the auction.
• The reference to 2021 performance is not defined as a precise, testable condition.
• Suggested additions include valuation ratios, moving averages, and MACD.
• The example implementation has unclear data fields and does not demonstrate a working strategy.
• The post provides no performance testing and warns that strong expectations may bring short-term risk.
