The Dow Jones Industrial Average closed just under the 25,000 marker Tuesday after earlier crossing the milestone for the first time since March 10.
The Dow closed at 24,995, up 530 points, or 2.2 percent, after earlier touching a session high of 25,176.
The average first passed 25,000 in December 2017.
Meanwhile, the S&P 500 similarly crossed 3,000 for the first time since March 5, but closed at 2,991, up 1.2 percent. The S&P, often seen as a better gauge of the market as a whole, first crossed 3,000 last July.
Markets were bubbly as cities and states across the country moved to scale back lockdowns and gradually open their economies back up.
But some saw danger in the differing approaches toward opening up.
Scott Gottlieb, President Trump’s former commissioner of the Food and Drug Administration, said Tuesday that the reopenings were leading to some worrying public health data.
“We now see a trend and an uptick in hospitalizations,” Gottlieb told CNBC. “It’s a small uptick, but it is an uptick and it’s unmistakable, and it is probably a result of reopening.”
