Screening Chinese Stocks by Price Range, Fund Flows, and Auction Turnover

Summary

The document describes a short-term Chinese equity screen combining prior-day price amplitude, appearance on the market’s unusual-trading list, net buying on that list, and auction turnover. Its stated selection logic looks for amplitude above 1, net buying by listed participants, and auction turnover above 0.26. A Python example intersects the qualifying stock sets and ranks candidates by turnover, while an indicator-formula example illustrates the same general screening idea.

The article frames volatility, unusual buying activity, and active opening-auction trading as signs of short-term market interest. It provides no backtest, performance statistics, or evidence that these signals predict returns. The implementation examples also contain inconsistencies: the indicator formula uses a different auction-turnover threshold, and the code’s ranking and data details may not align fully with the prose. The article itself notes that short-term enthusiasm can produce unstable returns and suggests combining the screen with fundamental and technical analysis.

Key ideas

• The screen combines price amplitude, prior-day unusual-trading-list activity, net buying, and auction turnover.
• The Python example intersects signal lists and ranks qualifying shares by turnover.
• The article presents short-term trading interest as a possible signal, without providing performance evidence.
• The formula example and written selection rule use inconsistent auction-turnover thresholds.
• The article warns that short-term signals can be unstable and suggests adding fundamental context.
