NEW YORK (Reuters) - The Dow Jones Industrial Average briefly broke above the 23,000-point mark for the first time on Tuesday, driven by strong earnings from UnitedHealth and Johnson & Johnson, but finished the session just below that milestone.
The blue-chip index, which surpassed similar 1,000-point marks three times previously this year, has been steadily inching higher and is up 2.6 percent so far this month, putting it on track for a seventh straight monthly advance.
The Dow may in the near term have a difficult time sustaining a move above 23,000, said Robert Pavlik, chief market strategist at Boston Private Wealth in New York.
"My view is it may pull back before staying above" that level. "It may take several days or a couple of weeks," he said.
"Right now, you're contending with earnings season and the fact that the market has run up leading up into the earnings season," Pavlik said.
Recent strong economic data and renewed hope that President Donald Trump may be able to make progress on tax reform also have helped lift stocks in recent weeks.
Shares of the largest U.S. health insurer UnitedHealth <UNH.N> touched a life intraday high and closed up 5.5 percent after the company reported a stronger-than-expected profit and raised its full-year earnings forecast.
