The S&P 500 finished at a fresh record on Thursday as markets took in stride data showing another spike in annual inflation last month to the highest rate in 13 years.
The most broad-based of the major equity indices gained 0.5 percent to finish at 4,239.18 to overtake the prior record set May 7.
The Dow Jones Industrial Average edged up 0.1 percent to 34,466.24, while the tech-rich Nasdaq Composite Index jumped 0.8 percent to close at 14,020.33.
The hotly-anticipated consumer price index report showed the US inflation rate accelerated to five percent for the 12 months ending May.
The increase was driven largely by spikes in energy and used car prices, which analysts attributed to separate but temporary factors.
"It's another case where we had another blockbuster inflation report and nobody cared," Karl Haeling of LBBW told AFP. "The market looked the other way."
Art Hogan, chief market strategist at National Securities, noted that while the annual CPI topped expectations, but the monthly gain slowed to 0.6 percent in May from 0.8 percent in April, which largely validates the Federal Reserve's stance that higher inflation will be transitory.
"We may be getting close to a peak and it will start to decelerate in the June-July timeframe," Hogan said.
