Micron Technology is trading 7.5% down at $199.50, as sector-wide concerns about Chinese chipmaker CXMT’s denser DRAM design and server-memory plans pressure memory stocks. - These concerns could intensify competition for established suppliers. - The Nasdaq is down 0.91% and the S&P 500 is down 0.61% amid hotter-than-expected headline inflation and renewed rate concerns. The sharper move in memory stocks points chiefly to sector pressure rather than a new Micron-specific announcement.
