China’s A-share benchmarks fell on the morning of July 8, with the Shanghai Composite Index down as much as 0.30% intraday, while coal, oil and petrochemicals, and computer-related stocks led gains and electronics and machinery lagged, according to Jiemian News. As of 10:00 a.m., ChinaAMC’s Consumer Electronics ETF (159732.SZ) was down 3.50%; component stocks included Lens Technology down 11.48%, JCET down 7.95%, and *ST Wingtech down 7.37%. Some names bucked the trend, with CVTE hitting the 10% daily limit and Huaqin Technology up 7.49%. On the news front, Samsung Electronics said it has begun mass production of its most advanced data-center storage device, which will be used in Nvidia’s upcoming Vera Rubin platform. Samsung said the device’s read/write speed is more than double that of the previous generation and it uses liquid cooling to sustain high-speed operation during AI training and inference. TrendForce data showed Samsung’s enterprise SSD market share reached 35% in Q1 2026, ranking first globally. Guosheng Securities said AI workloads are driving higher technical requirements for SSDs, including performance, endurance, heat dissipation and data consistency, and that NAND value could be reassessed in the AI era.
