U.S. Markets Mixed as Earnings, Tariffs Drive Swings

U.S. stock markets closed the week with mixed outcomes, driven by key earnings reports, trade issues, and the introduction of new tariffs. The Nasdaq gained slightly, while the S&P 500 and Dow Jones slipped, reflecting volatility across sectors. The Trade Desk's stock plummeted nearly 29% in after-hours trading, despite beating revenue expectations, as its CEO pointed to volatility among major clients. Eli Lilly's shares suffered their worst single-day drop in 25 years, falling over 14% after its obesity pill failed to meet weight loss targets, despite otherwise strong quarterly earnings. Other companies like DoorDash, Duolingo, and Paycom Software posted robust results, while Fortinet and Snap saw sharp declines following weak performances and analyst downgrades. Grocery Outlet and Costco benefited from strong sales and positive outlooks, underscoring divergent trends across the market.
