Luckin Coffee is trading at $33.85, up 4.03%, with no clear company-specific catalyst identified. - On September 28, 2026, the company announced its 100th Singapore store, describing its local expansion and customer reach; it did not attribute the share-price move to the milestone. - Broader U.S. markets were lower amid rising oil prices and Treasury yields, a market backdrop that does not explain Luckin Coffee’s gain.
