The 30-stock average has closed at a record high for nine straight days, and it's up 10 in a row overall. Any gain on Tuesday would push the streak of records to 10, something that's only happened four other times since the Dow was established in 1896, according to Bespoke Investment Group.
The record for consecutive records is 12. It was set in January 1987, months before the Black Monday crash, and tied in February, shortly after President Trump took office.
In other words, the market isn't exactly going straight up. CNNMoney's Fear & Greed Index is sitting in "greed" mode, which is actually down from "extreme greed" a year ago.
Nonetheless, the Dow has surged about 3,800 points since Trump's victory in November.
In recent months, Wall Street has managed to shrug off turmoil in the Trump administration and the president's failure to get his economic agenda through Congress. Instead, the market has been carried to new heights by strong corporate profits from the likes of Apple, Boeing and McDonald's.
Wall Street is also feeling good about the economy. The unemployment rate dipped in July to a 16-year low of 4.3%, and employers have added more than 1 million jobs since Trump took office. Economic growth doubled to 2.6% during the second quarter.
The Federal Reserve has promised to raise interest rates at just a gradual pace to avoid disrupting the recovery or the markets.
Evidently, many investors believe the market will do just fine even if Trump fails to deliver on his promise of "massive" tax cuts.
Still, it could be healthy for the market to take a breather after all these records. The S&P 500 hasn't suffered a downturn of 5% or more in 406 days, the longest streak since May 1996.
Challenges may loom for the market in the coming weeks. Congress needs to raise the debt ceiling to avoid a disastrous default. The Treasury Department has estimated it can meet its financial commitments for two more months.
