NEW YORK, NY - MAY 21: Traders and financial professionals work ahead of the closing bell on the floor of the New York Stock Exchange (NYSE), May 21, 2018 in New York City.

As investors tried to evaluate the implications for the stock price of FB, many investors sold the other FANG members, as well as a number of the other big-cap tech stocks.
