Technology stocks fell under intense pressure on Monday after Bloomberg and The Wall Street Journal reported plans of federal regulatory probes into Facebook and Google's parent company, Alphabet, slamming the sector.

Meanwhile, The Wall Street Journal reported late Friday, citing people familiar with the matter, that the Department of Justice was preparing an investigation of Alphabet's Google unit over antitrust concerns.
