A-Share Screen for Recent Limit-Ups, Seven Down Days, and Buying Activity

Summary

This A-share screening idea combines investor-position growth above 5%, seven consecutive declining sessions, and at least two limit-up events within the prior 500 days. The rationale is to look for buying interest in stocks that have a history of sharp upward moves but have recently weakened. The article then proposes an adjusted screen: retain the buying-activity threshold, require at least three prior limit-ups, and allow a decline streak of up to seven days.

The discussion describes possible interpretations and risks, including that rising investor positions can accompany overvaluation and that a sustained losing streak may signal continued weakness. It offers no backtest, performance evidence, or precise operational definitions for investor-position growth and limit-up counting. Its code sample is incomplete and does not clearly implement the stated screening logic, so the screen should be treated as an informal concept rather than a validated strategy.

Key ideas

• The initial screen combines investor-position growth above 5%, seven consecutive down sessions, and at least two limit-ups in 500 days.
• The proposed revision raises the historical limit-up requirement to three and caps the decline streak at seven days.
• Rising investor positions may reflect buying interest, but the article also flags possible overvaluation.
• The screen gives no performance evidence and leaves key signal definitions unclear.
