Ranking A-Shares by Auction Turnover After Turnover and Exchange Filters

Summary

This note proposes screening Chinese A-shares for a turnover rate between 3% and 12%, excluding Beijing-listed shares, then selecting the five stocks with the largest amount traded in the day’s auction. Its rationale is that high auction activity may identify stocks attracting attention. It suggests improving the screen with fundamental and technical measures, or adjusting the ranking rule to reflect market conditions.

The document offers no performance results or evidence that high auction turnover forecasts gains. It warns that unusually active stocks may be subject to manipulation and that volume-based ranking alone can select companies with weak fundamentals or technical profiles. The sample Python excerpt ranks daily amount and takes five names, but it does not implement the stated turnover band, Beijing exclusion, or auction-specific measurement. As presented, it is therefore an incomplete illustration rather than a reproducible test of the full selection rule.

Key ideas

• The proposed screen applies a 3% to 12% turnover band and excludes Beijing-listed shares.
• It ranks the remaining stocks by auction trading amount and selects the top five.
• The article flags manipulation and the omission of fundamentals or technical context as risks.
• The code excerpt does not implement all of the stated filters or the auction-specific ranking.
