FACTBOX-Dow breaches 23,000 intraday mark: facts & figures

NEW YORK, Oct 17 (Reuters) - The Dow Jones Industrial

Average briefly ticked above 23,000 on an intraday basis

on Tuesday, putting it on track for its fourth-shortest gallop between thousand-point milestones in its more than 100-year history. It took the index 107 trading sessions from its first close above 21,000 on March 21 to 22,000 but only 24 sessions to move from 20,000 to 21,000 earlier this year, tied for the shortest such span in its history. The 30-stock index is on track for a third session of gains, and on Friday the Dow posted a fifth straight week of gains.

If the Dow closes above 23,000, it would be the index's fourth thousand-point milestone so far this year. The Dow was last up 0.1 percent at 22,974.15. Below is a list of facts about the index and its climb to 23,000:

** The longest stretch between such milestones has been the 3,630 days needed for the index to close above the 2,000 barrier, reached on Jan. 8, 1987.

** The Dow closed above 22,000 for the first time on Aug. 2.

Since then, Caterpillar Inc has been the largest

percentage gainer within the index, with a more than 15 percent

increase, while Boeing Co has contributed the most to the

index's gain with close to 140 points.

** Nike Inc has been the largest percentage decliner

since Aug. 2, with a drop of over 13 percent. Walt Disney Co has weighed the most on the index with a more than 71-point drag on the Dow since Aug. 2.

** There was one constituent change in the index since the

last 1,000-point milestone as DuPont was replaced by DowDuPont Inc on Sept. 1.

** U.S. President Donald Trump opened a news conference with Greek Prime Minister Alexis Tsipras by noting the index's achievement: "It broke for the first time ever 23,000. So, we're very happy about that," he told reporters.
