US Stock Market Move | Storage sector opens collectively strong, SK Hynix (SKHY.US) up over 10%

On Tuesday, the storage sector opened collectively strong, with SK Hynix (SKHY.US) up over 10%, SanDisk (SNDK.US) up over 6%, Western Digital Corporation (WDC.US), Seagate Technology Holdings PLC (STX.US) up over 4%, and Micron Technology, Inc. (MU.US) up over 3%. In terms of news, it was reported that SK Hynix has officially started mass production and delivery of 12-layer HBM4 for NVIDIA Corporation, with the product entering the capacity ramp-up phase. Unlike the previously supplied products classified as samples, this is the first time HBM4 has been completed in all quality certifications for NVIDIA Corporation's next-generation AI platform "Vera Rubin". It is reported that starting in September this year, SK Hynix will officially expand the scale of HBM4 deliveries to fully meet NVIDIA Corporation's high-end computing chip supply demands. In addition, the US June CPI year-on-year fell to 3.5%, with the largest monthly decline since 2020, while the core CPI remained flat at 2.6%. As overall inflation in the US fell as expected in June, traders significantly cut their bets on a Fed rate hike, which also contributed to the strong performance of the storage sector.
