US Stocks Reverse Early Gains as Chipmaker Declines and Mixed Earnings Weigh
Major US stock benchmarks pulled back from their session highs on Tuesday, with the S&P 500 (SP:SPX) sliding 0.22% to end at 7,790. Equity markets surrendered early strength as Treasury bonds reversed gains, creating pressure on AI infrastructure stocks while investors evaluated a series of major corporate earnings reports.
Technology shares declined heavily after reports surfaced that Chinese memory maker CXMT developed a new memory architecture threatening US and South Korean competitors. Market sentiment in the sector took a further hit when Broadcom (AVGO) CEO Hock Tan cautioned that high capital outlays by AI labs are returning disappointing results. The warning triggered drops of 4% to 6% across Micron Technology (MU), Marvell Technology (MRVL), and SanDisk. Outside of tech, earnings results were mixed. Johnson & Johnson (JNJ) dropped 5.5% following soft sales numbers, while UnitedHealth Group (UNH) picked up 2% on an upgraded profit forecast. Financial giants also diverged, as Goldman Sachs (GS) rose 1% and JPMorgan Chase (JPM) gained 1.5%, offsetting losses in Citigroup (C), which fell 2%, and Wells Fargo (WFC), down 1.4%.
Investors will watch upcoming corporate earnings announcements and bond market yields to see if market volatility persists. Participants will also monitor capital expenditure trends in artificial intelligence to assess whether technology valuation pressures will continue in subsequent trading sessions.
