Chinese Stock Screening with Amplitude and Auction Net Buying

Summary

The document presents a Chinese equity screening rule combining three conditions: daily amplitude above one percent, a stock code beginning with 60, and positive net buying attributed to major participants during the opening auction. It explains amplitude as a sign of higher volatility and treats positive auction net buying as a possible sign of demand. Formula and Python references illustrate how to apply the filters.

The post cautions that auction buying may produce false signals and that high-amplitude stocks carry greater risk. It suggests combining the screen with technical, financial, or fundamental factors, including a multi-factor model. No backtest, trading results, holding period, or execution rules are provided, so the proposed demand interpretation and investment value are not validated. The screening conditions alone do not establish that selected stocks will outperform.

Key ideas

• The screen requires amplitude above one percent, a code starting with 60, and positive opening-auction net buying.
• The post interprets larger amplitude as higher volatility and positive net buying as possible demand.
• Auction net buying can produce misleading signals, and volatile stocks carry greater risk.
• The author suggests adding technical, financial, or fundamental factors.
• No backtest or evidence of strategy performance is presented.
