China's CXMT DRAM breakthrough triggers global memory‑stock sell‑off
China’s ChangXin Memory Technologies (CXMT) announced progress on a next‑generation 4F² DRAM cell design, promising a server‑memory product by the end of 2026. The news sparked a sharp decline in memory stocks, with Micron Technology falling to around $990‑$1,000, SK Hynix and SanDisk losing over 4% each, and the Roundhill Memory ETF dropping more than 4%. Analysts linked the sell‑off to fears of heightened competition and potential pressure on DRAM pricing and margins.
Why it matters
The sell‑off erased roughly $108 billion of market value from Micron, SK Hynix and SanDisk (), widening the gap between current prices and analysts’ price targets and increasing downside risk for investors holding these stocks. The heightened competition risk may compress future DRAM pricing, affecting earnings forecasts for the sector.
