S&P 500 dips as Fed Chair warns on inflation risks

The S&P 500 fell into the red and never made it back to positive territory after Fed Chair Jay Powell warned of more tariff-induced pressure on inflation to come, causing traders to price in lower odds of interest rate cuts. The benchmark US stock index fell 0.1%, the Nasdaq 100 gained 0.2%, and the Russell 2000 slumped 0.5%.

Materials, energy, and real estate were the worst-performing S&P 500 sector ETFs, while utilities, communications services, and tech were the lone sectors to gain on the day.

Humana rose more than 12% after the health insurance company topped Q2 estimates and raised its full-year outlook. Big decliners included mining giant Freeport-McMoran, which tumbled after the Trump administration announced tariffs on imports of processed copper products, but excluded ore and cathodes.
