The Dow Jones industrial average closed at a record high on Monday as Wall Street cheered on what's been a strong earnings season.
The 30-stock index rose 60.81 points to close at 21,891.12 with Goldman Sachs and Home Depot contributing the most gains. Boeing also contributed gains, with shares rising half a percent after announcing it expects a record number of aircraft orders from India. The announcement came about a week after posted better-than-expected quarterly results.
The S&P 500 closed 0.07 percent lower at 2,470.30 as materials and information technology lagged. The Nasdaq composite underperformed, falling 0.42 percent to end at 6,348.12 as large-cap tech stocks like Facebook and Alphabet pulled back.
"What's driving this market in the short term is earnings," said Atul Lele, chief investment officer at Deltec International Group. "Earnings are being driven by the recent economic expansion, which we think still has room to run."
This earnings season has largely provided positive surprises for investors. Seventy-three percent of the S&P 500 companies that had reported as of Friday had topped estimates on both the top and bottom lines, according to data from FactSet.
These results, along with stabilizing oil prices and persistently subdued sovereign bond yields, have allowed the stock market to keep notching record highs, said Peter Cardillo, chief market economist at First Standard Financial.
"We keep seeing political and geopolitical tension creeping up and the market seems to be taking that in stride," Cardillo said.
North Korea tested an intercontinental ballistic missile last week which landed in the Sea of Japan, raising concerns that more parts of the U.S. could be at risk of an attack. Meanwhile in Washington, the White House saw a major shake-up after John Kelly replaced Reince Priebus as President Trump's chief of staff.
Equities reached record highs last week, but some strategists say the technical backdrop for stocks shows investors should be cautious.
"The markets are entering a historically weak seasonal period accompanied by rising investor optimism. Historically, the period from August through October has seen stocks struggle and a period when corrections have tended to occur most often," Bruce Bittles, chief investment strategist at Baird, said in a note.
Up on the earnings docket for this week are Apple, Mondelez, Yum Brands and Tesla, among others.
