Chinese Stock Screen Using Intraday Inflows and Auction Returns

Summary

The screen selects Chinese stocks using three conditions: daily price amplitude above 1%, afternoon large-order net inflow, and an opening auction return between -2% and 5%. It then describes choosing the stock with the highest gain among qualifying candidates. The article presents these criteria as a short-term activity and trading signal, and includes reference formulas and sample code for implementing the screen.

The article warns that the method omits longer-term fundamentals and that auction returns may be affected by outside factors. It suggests adding indicators such as moving averages or MACD, but provides no backtest results or evidence that the proposed filters predict returns. The included code also does not clearly operationalize the ranking described in the text, so the implementation should be checked before use. The rules are specific to stock data and need careful validation before being treated as a strategy.

Key ideas

• The screen filters stocks by price amplitude, afternoon large-order net inflow, and opening auction return.
• The stated auction-return range is -2% to 5%.
• The article proposes selecting the strongest gainer among stocks that pass the filters.
• It cautions that the rules omit long-term fundamentals and that auction data can be affected by external factors.
• No backtest evidence is provided, and the sample implementation should be checked against the stated ranking logic.
