Super Micro Computer, which sells AI optimised servers built with Nvidia chips, climbed nearly 5%. Nvidia CEO Jensen Huang this week was the subject of wall-to-wall coverage on Taiwanese television and was mobbed by attendees when he visited the Computex tech trade fair in Taipei, where he was born before moving to the US. While Nvidia rides a wave of AI enthusiasm on Wall Street, Apple is struggling with weak demand for iPhones and tough competition in China, the world's biggest smartphone market. Some investors also view Apple as lagging behind other technology heavyweights as they rush to build AI features into their products and services. Reuters
