US Stocks: Nasdaq, S&P end lower as tech megacap declines outweigh upbeat chip outlook

US stock indices closed mixed to lower on Thursday, with the Nasdaq and S&P 500 declining as sell-offs in Big Tech over AI spending concerns outweighed strong earnings from chipmaker Micron. The Dow edged higher. Fresh data showing rising inflation alongside robust GDP growth fueled uncertainty about the Federal Reserve's next policy move, keeping investors cautious. Indian markets also closed mixed, reflecting the global risk-off sentiment.
