US Stocks Dip as Chinese CXMT Pressures Chipmakers, Banks Weigh

US indices closed slightly lower on Tuesday, dragged by chipmakers reacting to Chinese memory chip firm CXMT's competitive moves and by bank sector weakness. The decline is modest, suggesting market participants are pricing in sector-specific pressures rather than broad risk-off. Uncertainty remains over the extent of CXMT's impact on global semiconductor pricing and whether bank weakness signals broader credit stress.
