The Dow Jones Industrial Average crossed 40,000 for the first time in history on Thursday.
This is a significant and symbolic milestone for the index that tracks 30 of the most valuable publicly traded companies in the U.S.
The Dow is now up about 6% so far this year.
The recent rally in the Dow, S&P 500 and Nasdaq has been fueled by data showing inflation is cooling, which would allow the Federal Reserve to begin its long-awaited interest rate cuts.
