For years, the technology sector has been on a tear. But this year, it's fallen on hard times.
The popular FANG basket of tech stocks—Facebook, Amazon, Netflix and Google (now Alphabet)—has cooled after leading the market in gains last year, and the tech-dominated Nasdaq 100 index has tumbled into correction territory.
