While the Dow rose to 35,725.11 points, crossing its intraday high of 35,679.13 points hit in August, all three main indexes were on course for their strongest November since 2020.
The S&P 500 (.SPX) and the tech-heavy Nasdaq (.IXIC) were also poised for their biggest monthly percentage gain since July 2022, on signs of cooling price pressures.
The personal consumption expenditure (PCE) index - the Fed's preferred inflation gauge - showed inflation remained unchanged in October on a monthly basis, against economists' projections of a 0.1% increase.
Core inflation, which excludes volatile food and energy prices, rose 0.2% on a monthly basis, in line with estimates.
But most megacap stocks edged lower, with Tesla (TSLA.O) down 1.4% and leading declines, keeping the S&P 500 (.SPX) and Nasdaq (.SPX) under pressure.
