Tuesday's market saw mixed futures as investors awaited tech earnings and the Fed meeting. Top gainers included OPKO Health (+9%), Celestica (+4%), and Applied Digital (+4%), all driven by strong Q2 results and raised guidance, particularly in AI infrastructure. Conversely, Aehr Test Systems (-5%) fell due to a shelf registration filing, and Universal Health Services (-4%) declined after cutting FY2026 EPS guidance and reporting lower-than-expected earnings.
