A-Share Rebound Screen Combining Seven Losing Sessions and Recent Limit-Ups

Summary

The proposed A-share screen combines a reported increase in institutional position share above 5%, seven consecutive declining sessions, and more than two limit-up days within the past ten trading days. The author frames the long decline as a possible oversold rebound setup, while recent limit-ups and position increases are treated as signs of attention or potential inflows. The final suggested logic also adds price-to-earnings below 20 and price-to-book below 1 as valuation filters.

The post gives a short Python-style selection example, but its code checks that the seven-day decline condition is false, which conflicts with the stated strategy. It also provides no backtest, data definition, or evidence that the indicators predict a rebound. The text acknowledges that prolonged losses can continue and that stocks with recent limit-ups can see money exit. The thresholds and position-share measure would need precise definitions before evaluating the idea.

Key ideas

• The stated setup combines recent position increases, seven declining sessions, and multiple recent limit-up days.
• The final version adds price-to-earnings and price-to-book thresholds.
• The code example contradicts the stated seven-day decline requirement.
• The document offers no backtest and notes that prices can keep falling or inflows can reverse.
