On October 23, SK hynix rose 3.04% Overnight, trading at $134.99/share, with turnover of $27.12 million.

The move followed reports that the company has begun coordinating with materials, components and equipment suppliers to prepare commercialization and mass production of next-generation iHBM technology, while investors also looked ahead to its October 27 earnings release.

Recent coverage said SK hynix is discussing product introduction plans and volume production timing for iHBM, a technology the company unveiled in May. Separately, consensus expects quarterly revenue of about $70.07 billion, up 293.53% year over year, while one brokerage projected third-quarter sales of KRW 101.2 trillion and operating profit of KRW 81.3 trillion, citing strong AI-driven demand for HBM, DRAM and NAND pricing. On the same day, reports also said Solidigm discontinued its review of pre-IPO and IPO options, but the overnight rise was more directly aligned with the later iHBM and earnings-related developments.
