US Premarket: Tesla Falls ~5%; Chips and Optical Networking Weaken

Tesla fell about 5% in U.S. premarket trading after the company missed third-quarter revenue estimates and lowered its capital-expenditure targets, putting capex repricing at the center of the session. Semiconductor and optical-networking shares also weakened: IBM and Intel each fell about 5%, Micron Technology declined about 3%, NVIDIA lost about 2%, and Marvell Technology fell about 5%. Cloud-infrastructure names were lower as well, with Nebius down about 6% and CoreWeave down about 5%. Meta edged higher after its Q3 revenue and Q4 guidance both exceeded expectations; the company raised the lower end of its AI capital-expenditure range and plans to issue new non-voting shares.
