Stock market today: Dow, S&P 500, Nasdaq sink as bond yields jump to cap volatile week ahead of Nvidia earnings

U.S. equities slid Friday as rising Treasury yields and renewed inflation worries undercut markets ahead of key corporate results, notably Nvidia’s upcoming earnings. The Nasdaq fell about 1.5%—Nvidia (NVDA.OQ) shares were down roughly 3–4%—while the S&P 500 retreated ~1.2% and the Dow lost ~1% (about 530 points), slipping below 50,000. A global bond rout pushed the 10-year yield near 4.57–4.59% and the 30-year above 5.1%, tightening financial conditions and hitting precious metals; gold and silver dropped sharply. Energy prices rose (Brent ~ $109/bbl), supporting the energy sector even as tech and semiconductors came under pressure. Markets enter a volatile week centered on NVDA’s earnings and inflation- and geopolitics-driven rate concerns.
