It took literally all of Friday's trading session, but the Dow Jones Industrial Average hit its first close above 40,000.
The blue-chip average finished at 40,000.59, up 132 points, or 0.34% right at the 4 p.m. ET close. The index had hit an intraday high of 40,51.05 on Thursday before dropping back to 39,865.
The Dow's performance was the day's best among the major averages. The S&P 500 was up 6 points, or 0.1%, to 5,303. The Nasdaq Composite was down 12 points, or 0.1%, to 16,685.97.

The S&P 500 and Nasdaq (as well as the Dow) had hit record closes on Wednesday.
The index was up 1.2% for the week. It has climbed 5.8% so far in May and has risen 6.1% for the year.
The Dow on Friday was pushed higher primarily by gains in Caterpillar (CAT) , UnitedHealth Group (UNH) , Goldman Sachs (GS) , JPMorgan Chase (JPM) , and Boeing (BA) .
The Dow's big move this past week is part of a massive stock-market rally that erupted in late October.
Since the market bottomed in October, the blue-chips have risen more than 23%. The S&P 500 is up 28.8%, and the Nasdaq has jumped 32.5%.
Why stocks have risen since October
The initial catalyst for the big rally was the Federal Reserve's signal it had basically finished raising rates to beat down inflation.
An additional fuel was investors' realizing a recession in 2024 was probably not going to happen.
Then, investors became enamored with the potential of artificial intelligence, pushing shares of Nvidia (NVDA) up 87% this year after a 239% gain in 2023.
