Stocks struggled on Monday as investors worried about a deluge of corporate earnings reports coming this week as well as rising geopolitical tensions.
The Dow Jones Industrials trashed 143.25 points to 25,301.09, led by declines in United Technologies and DowDuPont.
The S&P 500 docked 10.07 points to 2,757.71, as energy and financials lagged.

The Shanghai Composite rose more than 4% to notch its best day since March 2, 2016.

Chinese stocks are still down sharply this year despite Monday's jump. The Shanghai Composite has plummeted about 20% in 2018 and is down 21.4% over the past year.
