The Nasdaq 100 has seen better days.
The index, which is composed of the 100 largest nonfinancial companies in the broader Nasdaq composite, fell more than 1.5 percent Thursday, erasing its post-U.S. election gains, as shares of Apple and the so-called FANG stocks (Facebook, Amazon, Netflix and Google parent Alphabet) all fell.
The Nasdaq 100's decline began Wednesday, when it dropped 1.3 percent. Entering Wednesday's session, the index had gained 2.4 percent. As of 3 p.m. ET Thursday, the Nasdaq 100 was down about half a percent since Nov. 8.
