The US stock market's storage sector pulls back as Samsung and SK Hynix's new capacity plans raise concerns about oversupply.

The US stock storage sector opened under pressure, with Micron Technology and SanDisk stock prices falling. Samsung and SK Hynix announced an 800 trillion KRW investment plan to build a new chip manufacturing hub, together accounting for two-thirds of the global memory chip production capacity. The planned expansion of capacity is expected to put pressure on the supply curve for FY27–FY28, causing direct DRAM/NAND stocks to come under strain, while companies mainly engaged in memory structure or hard disk business performed relatively resiliently.
