The megacap tech shares that drove stocks to record after record plunged Thursday as bearish investors reclaimed the upper hand on U.S. equity markets, at least for a day.
The Nasdaq 100 sank 5.2% and posted its biggest rout since March. Apple Inc., Tesla Inc. and Amazon.com Inc., among the biggest contributors to the historic five-month rally, lost at least 4.6%. The index had gained in 11 of 13 sessions to notch records almost daily, defying strategists who warned that valuations had become too stretched.
