The Dow Jones industrial average rose on Tuesday, and broke above 23,000 for the first time on an intraday basis.
The index faded and closed three points shy of 23,000 as bank shares rolled over.
The Dow first crossed 22,000 for the first time just 76 days ago.
"Those big, round numbers are getting easier to reach on the Dow on a percentage basis," said Art Hogan, chief market strategist at Wunderlich Securities. "That's great because every time we get a milestone like that, it seems like Mainstream America pays more attention to financial markets."
Boeing and Caterpillar were the biggest points contributors on the Dow since Aug. 2, when the index first broke above 22,000. They added 142 points and 121 points, respectively. The two stocks have had a stellar year, rising 65.9 percent and 41.2 percent, respectively.
Home Depot and Goldman Sachs, meanwhile, contributed 97 points and 87 points to the Dow's latest 1,000-point run.
