A-Share Screen for Recent Limit-Ups, Intraday Drawdown, and Position Growth
Summary
This short-term A-share screen selects stocks with position growth above 5%, a maximum intraday decline between 4% and 5%, and more than two limit-up sessions during the preceding ten days. The proposed interpretation is that rising position share may indicate capital inflow, the sharp but bounded decline could create a rebound opportunity, and repeated limit-ups signal recent activity and attention. Sample code describes combining data for these conditions and ranking candidates, though it does not provide a reproducible data source or a complete, consistent implementation.
The document supplies a screening hypothesis rather than evidence of effectiveness: it reports no backtest, returns, or risk statistics. It acknowledges that the rules emphasize recent price action and technical factors while leaving long-term trend and company fundamentals underexamined. It suggests adding valuation and financial quality measures, as well as a check that short-term trend remains positive. The rebound premise is especially uncertain because a large decline may reflect continuing adverse information rather than temporary weakness.
Key ideas
- The screen combines position growth above 5%, a 4% to 5% maximum intraday decline, and more than two recent limit-ups.
- The article interprets position growth and repeated limit-ups as signs of capital interest and activity.
- A sharp intraday fall is treated as a possible rebound setup, but the document provides no empirical validation.
- The author recommends adding fundamental and trend filters to address the strategy's short-term focus.
