A-Share Screening with Turnover and Auction Order Flow

Summary

This strategy screens Chinese A-shares by requiring turnover between 3% and 12%, excluding Beijing-listed stocks, and selecting stocks where large and extra-large buy orders during the opening auction exceed the stated volume threshold. The accompanying explanation interprets the turnover range as a way to avoid unusually volatile or illiquid stocks and treats large-order buying as evidence of demand that may support prices.

The article cautions that the screen omits fundamental analysis and that auction order flow may be distorted by market expectations, policy changes, or manipulation. It suggests combining the signal with indicators such as RSI or KDJ and company financial and business information. No performance results or empirical validation are provided, and the included code sketch appears to query money-flow data for only the first selected ticker, so it does not demonstrate a complete implementation of the stated screen.

Key ideas

• The screen uses a 3% to 12% turnover band and excludes Beijing-listed A-shares.
• It selects for large and extra-large buying during the opening auction above a stated volume threshold.
• The article presents turnover as a liquidity and volatility filter, but offers no performance evidence.
• Auction order flow can be misleading, so the author recommends adding technical and fundamental checks.
