Screening Stocks by Morning Gap, Large-Order Flow, and Turnover
Summary
The document proposes a Chinese stock screen using three signals: rank by turnover as a proxy for capital activity, rank by net large-order volume as a measure of aggressive buying versus selling, and retain stocks whose indicated pre-open gain at 9:25 is below 6%. The rationale is that active turnover and positive large-order flow may indicate buying interest, while a limited opening gain avoids selecting stocks with the largest pre-open jumps.
The article warns that the combined screen may favor stocks with sharp short-term moves influenced by sentiment or policy. It recommends adding technical and fundamental review, including profitability, financial condition, and industry outlook. The provided code reference is incomplete, and the page gives no complete ranking implementation, portfolio rules, backtest, or evidence that the proposed signals predict returns. Turnover and order-flow measures also require precise data definitions and timing to be reproducible.
Key ideas
- Rank candidates by turnover and net large-order buying activity.
- Filter for a 9:25 pre-open price gain below the stated threshold.
- The rationale treats turnover and net order flow as proxies for active buying interest.
- Short-term moves may reflect sentiment or policy and can carry additional risk.
- The document lacks a complete implementation and performance evidence.
