Tech stocks live: SK Hynix begins trading on Nasdaq, SpaceX stock tumbles

Tech stocks were mixed as investors balanced strong AI-related demand against growing signs of strain in the PC market. SK Hynix began its Nasdaq debut, while SpaceX fell below its IPO opening price after entering the Nasdaq-100. The broader AI trade remained volatile: Meta rallied on comments that it may sell excess computing capacity, but semiconductor and memory names were under pressure amid concerns that elevated chip prices and a global memory shortage will slow PC shipments later in 2026. IDC said PC shipments fell 4.9% in Q2, the first decline in two years, and warned the shortage may not ease until early 2028. The article suggests continued dispersion within tech, with hardware and memory winners benefiting from AI capex while consumer PC demand weakens.
