U.S. stocks accelerated losses at the end of the day Wednesday, with the Dow dropping 600 points and the Nasdaq on pace for its biggest monthly drop in a decade.
The Dow Jones Industrial Average closed the day down 608 points, the S&P lost more than 3 percent, and the tech-heavy Nasdaq lost nearly 4.5 percent.
The sell-off was driven in part by a Commerce Department report that home sales plunged 5.5 percent in September, which rattled investors who expected only a slight decline.
Tech stocks especially weighed on markets. Netflix ($NFLX) and chipmaker Nvidia ($NVDA) were both down nearly 10 percent, Facebook ($FB), down nearly 6 percent, and Google parent Alphabet ($GOOGL), down more than 5 percent.
