Chinese A-Share Screen for Recent Limit-Ups and Intraday Declines

Summary

This stock-selection rule screens companies in the metaverse sector for a limit-up day within the previous 25 days and a current-day decline between 4% and 5%. It proposes running the screen before 10 a.m. The accompanying Python example filters a daily data frame using the current day’s percentage change and whether a recent limit-up date is recorded. The stated criteria describe a screening idea; the example does not show how to execute trades or manage selected positions.

The article argues that combining sector membership, a recent sharp rise, and a notable decline may identify stocks with market attention. It also acknowledges that the criteria are technically simple, the earlier surge may leave an expensive entry price, and early screening can miss later news. It suggests adding price-volume or candlestick analysis and stronger risk and position controls. No historical test, performance data, or evidence supports the claimed rationale, so the screen should be treated as an unvalidated hypothesis.

Key ideas

• The screen targets metaverse-sector stocks with a limit-up day in the prior 25 days.
• It selects stocks whose current decline is between 4% and 5%, with screening before 10 a.m.
• The example filters by daily percentage change and the presence of a recent limit-up date.
• The article notes risks from simple criteria, elevated entry prices, and news arriving after the screen runs.
• It offers added price-volume analysis and risk controls as possible improvements but reports no test results.
