Mainland Stock Screen Combining RSI, Daily Gains, and Auction Net Buying
Summary
This article outlines a screen for mainland Chinese equities that selects main-board stocks with a 14-period RSI below 65, a daily gain above 1%, and positive net buying attributed to major traders during the opening auction. It frames the conditions as a combination of momentum, market sentiment, and buying pressure, and includes example implementations for stock filtering and ranking candidates by the net-buy measure.
No backtest, return series, or other performance evidence is provided. The article notes that the screen excludes company fundamentals and may become ineffective as market conditions shift; it also flags the risk of overlooking sector and policy factors. It recommends combining technical and fundamental measures, examining broader capital-flow information, and using diversification and risk controls. The sample code’s data and calculation details do not clearly establish that the described auction flow and daily return are measured consistently across all candidates, so implementation assumptions should be checked before evaluation.
Key ideas
- The screen combines RSI below 65, a daily gain greater than 1%, main-board eligibility, and positive opening-auction net buying.
- The proposed rationale combines recent price behavior with a measure of buying pressure.
- The article provides no evidence from backtesting or live results.
- It identifies missing fundamental, sector, and policy information as limitations.
- It recommends broader inputs, diversification, and risk controls.
