Screening Chinese Stocks for Three-Day Limit-Up Momentum

Summary

This proposed stock screen combines a daily price-range threshold, three consecutive prior limit-up sessions, and an indication of large-player control. The article frames these conditions as ways to find active stocks with strong buying interest. Its sample Python logic approximates the conditions using price range, prior percentage changes, and changes in open interest, although the supplied contract example and proxy measures do not clearly match the stated stock-screening criteria.

The article recommends checking industry and fundamental characteristics alongside the signal and warns that chasing repeated limit-ups can neglect long-term value, that the control measure is difficult to assess, and that high valuations may encourage excessive buying. It presents no backtest or performance evidence. The screen is therefore an illustrative momentum idea with ambiguous definitions and substantial implementation and concentration risks, rather than a validated strategy.

Key ideas

• The proposed screen looks for a price range above one, three consecutive prior limit-up days, and a measure of large-player control.
• The sample code uses price changes and open-interest changes as proxies, but their relationship to the described stock conditions is unclear.
• The article suggests supplementing the signal with industry and fundamental analysis.
• It cautions that repeated limit-ups and uncertain control data can lead to poor or concentrated decisions.
• No performance test is reported.
