Movement Alert｜SK hynix Falls 5.42% in Regular Trading, New Memory Launch Overshadowed by Broader Storage Selloff

Market Focus

Yesterday

On October 13, SK hynix fell 5.42% in Regular Trading, trading at $153.305/share, with turnover of $641 million.

The move came even after the company unveiled two new AI memory technologies at the OCP Global Summit: the MARS memory acceleration architecture and HBF high-bandwidth flash.

According to publicly available reports released the same day, MARS is designed to address AI inference memory bottlenecks and could improve time to first token by 3 to 5 times through memory disaggregation. SK hynix also introduced HBF, which offers about half the bandwidth of HBM but up to 14 times the capacity, with samples planned for early 2028. However, the stock remained under pressure alongside a broader decline in storage names, with Micron also down more than 5% as investors weighed competitive DRAM expansion risks and sector valuation concerns.
