Chinese Stock Screen Using Auction Returns and Daily Position Inflows

Summary

This note presents a Chinese stock screen using two short-term conditions: a daily increase in the share of positions held above 5% and an opening-auction return between -2% and 5%. It also limits the stated sample period to 2021. The document interprets the inflow measure as possible buying interest and the auction range as a sign of near-term price strength, then suggests adding profitability, financial stability, technical trend, industry, and policy filters.

No backtest or evidence is provided to support the signal interpretations. The note itself flags that the screen focuses on short-term trading data and may miss longer-term trends, fundamentals, and unusual situations. Its sample code and written conditions may not map cleanly to the stated auction and position-inflow measures, so the data definitions and implementation would need verification before research or use.

Key ideas

• The screen combines a daily position-increase share above 5% with an auction return from -2% to 5%.
• The stated historical period is 2021.
• The note proposes adding profitability, financial stability, trend, industry, and policy filters.
• No performance evidence is supplied, and the code may not implement the written conditions faithfully.
