Traders pulled back from risk assets, with a torrid run in US equities hitting a wall as April inflation data came in hotter than economists' estimates and worsening tensions between Washington and Iran sent oil prices higher.
The S&P 500 Index fell 0.2% on Tuesday in New York, while the Nasdaq 100 Index slid 0.9%.

For a third consecutive day, the share of S&P 500 companies making new 52-week lows eclipsed those notching 52-week highs despite the proximity of the benchmark to its last record, according to data from Thomas Thornton, president and founder of Hedge Fund Telemetry LLC. Even with stocks setting a string of highs, the poor market underpinnings reflect the fragility of the gains, with equity benchmarks being driven by a small share of stocks related to the artificial intelligence theme.
US inflation accelerated in April, driven by the climb in gasoline prices since the start of the Iran war. The consumer price index rose 3.8% from a year earlier, according to Bureau of Labor Statistics data out Tuesday, marking the fastest pace since 2023. Prices were up 0.6% from a month earlier.
The core CPI, which excludes food and energy, increased by a stronger-than-expected 0.4% from March and 2.8% from a year earlier, boosted in part by a statistical quirk in the report's measure of rents resulting from the 2025 government shutdown.

Global profit growth is at a four-year high, driven by technology companies, per Deutsche Bank AG's Binky Chadha. Corporate America has outstripped expectations by the widest margin outside the Covid-19 era since at least 2013, according to Bloomberg Intelligence data.
"Inflation is likely to take a back seat over the coming months as investors remain focused on earnings, economic growth, and the AI-driven capex cycle," said Tim Urbanowicz, chief investment strategist, Innovator ETFs from Goldman Sachs Asset Management, in an email. "The Fed has been clear that it is willing to look through any temporary inflation spike tied to the Iran conflict, and that remains the key consideration for investors in the near term."
A multitude of Wall Street firms in recent weeks - including RBC Capital Markets, HSBC Holdings Plc, and Barclays Plc - have upgraded their year-end S&P 500 forecasts on that strength.
