The escalating threat from North Korea and President Donald Trump's increasingly aggressive response kept global markets in fear this week. Here's what you need to know.
Where Markets Ended
Geopolitical uncertainty reigned for the bulk of the week as President Trump and North Korea traded escalating threats, though no concrete steps were made toward conflict.
For the week, the Dow Jones Industrial Average declined 1.1%, and the S&P 500 fell 1.4%. Those are the indexes' worst weekly losses since the week ended March 24. Markets had sold off then after House leaders pulled their health care bill before a crucial vote. Republicans were later able to push through a bill to the Senate, where it collapsed in late July.
The Nasdaq sank 1.5% this week, its worst loss since June 30. The index has suffered more frequent selloffs over the past two months as the tech sector snapped back from a significant run-up at the start of the year.
The Dow and S&P 500 clinched record closes on Monday, Aug. 7, marking the 35th all-time high for the Dow this year, a streak not seen since the 38 record closes in 2014.
