Lululemon shares fell 18% in extended trading Thursday and were down 17% in midday Friday after the athletic-apparel company reported disappointing fiscal second-quarter results and reduced its 2026 revenue outlook. Revenue declined 4% year over year to $2.42 billion, comparable store sales fell 9%, and management cited weak North American demand and continuing challenges in China. Lululemon also issued current-quarter guidance below expectations. Michael Burry, whose portfolio was 17.4% allocated to LULU, called the stock a "trickster" and said he would buy more below $100. The broader session featured sharp earnings- and outlook-driven moves, including declines in Guidewire Software, Oxford Industries, UiPath, Tesla and Asana, while semiconductor stocks and several companies that beat estimates advanced.
