NEW YORK (AP) Stocks dove again on Friday, extending recent declines, as traders worry about a U.S.-China trade war and slower economic growth.
Major U.S. indexes ended a tumultuous week down more than 4 percent Friday, marking the worst weekly decline since March.
The Dow Jones Industrial Average plunged more than 500 points Friday, bringing its weekly drop to more than 1,000.
Traders have been worried about worsening trade relations between the U.S. and China, the world's two biggest economies.
Those worries took a turn for the worse this week with the U.S.-ordered arrest of a senior Chinese technology executive.
The Dow fell 558 points, or 2.2 percent, to 24,388.
The S&P 500 lost 62 points, or 2.3 percent, to 2,633.
The tech-heavy Nasdaq fell 219 points, or 3 percent, to 6,969.
