With Memory chips (DRAM) down 4.1%, this looks like a sector-led move rather than a company-specific surprise.
Memory chip stocks are selling off sharply after Chinese competitor ChangXin Memory Technologies (CXMT) announced a significant advancement in DRAM architecture. This has sparked fears of increased competition and future pricing pressure for major producers like Samsung, SK Hynix, and Micron. This development threatens to disrupt the current supply-demand balance that has recently favored producers. Investors are concerned it could accelerate a peak in profitability for the sector, with Goldman Sachs warning of a potential supply-demand shift by 2028.
