U.S. stocks opened lower Tuesday as investors took a breather after the Dow Jones Industrial Average and the S&P 500 repeatedly refreshing record highs.
Both the broader S&P 500 and the blue-chip Dow set new all-time highs on Monday, as investors calmly greeted a batch of economic data that came out mixed.
The S&P 500 hit a new record intraday high of 1,925.88 points Monday before finishing at a record close of 1,924.97 points. Meanwhile, the Dow also logged an all-time intraday high of 16,756.64 points and a record close of 16,743.63 points.
