High-flying tech stocks stumbled sharply on Thursday, causing the S&P 500 to close with its worst drop since June.
The S&P 500 dropped 3.5 percent, wiping out more than a week of gains, while the tech-heavy Nasdaq composite was down nearly 5 percent. The Dow Jones industrial average briefly lost 1,000 points and ended the day down more than 800 points. Apple was down 8 percent. Amazon was down more than 4.5 percent, and Microsoft was down more than 6 percent.
