A-Share Screen for High Amplitude and Positive Auction Net Buying

Summary

This short-term stock screen selects shares with amplitude above 1, ranks them by the day’s auction amount, keeps the top five, and requires positive net buying attributed to major participants. The article’s rationale is that large price movement and active auction trading may signal market attention, while net buying may indicate investor interest. It also mentions trading volume as part of the strategy’s rationale and gives example indicator conditions and sample screening code.

The document offers no backtest results or evidence that the screen predicts returns. It warns that the approach relies heavily on technical and auction-flow data, overlooks company fundamentals, and may be affected by noisy or inaccurate net-buying figures. It suggests checking business quality and investor activity, and monitoring the auction data before using the screen. The article frames the conditions as a candidate-selection method, not a validated trading system.

Key ideas

• The screen requires amplitude above 1, top-five ranking by the day’s auction amount, and positive auction net buying.
• The article associates high activity and positive net buying with possible short-term market interest.
• The document provides example indicator conditions but reports no performance test.
• Auction net-buying data may be volatile or inaccurate, and the screen omits fundamental analysis.
