A Mainland China Stock Screen Using RSI, Daily Gain, and Opening Auction Change

Summary

This stock-selection recipe screens mainland China main-board shares using three conditions: RSI below 65, a daily gain above 1%, and a 9:25 change below 6%. The author presents the RSI threshold as a way to find shares with room to rebound, the positive daily move as a momentum filter, and the opening-auction cap as a way to avoid shares that have already risen sharply. The article also describes ranking candidates by circulating market value and gives sample query and Python implementations.

The rationale is qualitative; the document reports no backtest, benchmark, or realized returns. Its explanation calls RSI below the threshold oversold, although that interpretation is not established by evidence in the article. It also acknowledges that fixed conditions can miss changing market regimes, that fundamentals vary in relevance across industries, and that technical signals can be false. The implementation details and data fields may require adaptation to the chosen platform and available data.

Key ideas

• The screen selects main-board shares with RSI below 65, daily gains above 1%, and a 9:25 change below 6%.
• The author combines an RSI condition, positive daily momentum, and an opening-auction cap.
• The article suggests ranking candidates by circulating market value and supplies example implementations.
• The stated rationale is not supported by reported backtests or performance results.
• Fixed thresholds may fail as market conditions and industry characteristics change.
