TECH Tech’s big five lost nearly $270 billion in value in Thursday’s market plunge

The five most valuable tech companies lost more than $269 billion in value on Thursday, the worst day for U.S. stocks since March.

Microsoft was the biggest loser, shedding more than $80 billion in value as shares dropped more than 5%. Shares of Facebook were also down more than 5%, while Apple dropped 4.8%. Alphabet closed 4.29% lower and Amazon shed 3.38%.

Nearly every other tech stock was down as well, with Cisco (-7.91%) and IBM (-9.1%) seeing particularly steep drops. One exception was Zoom Video, which closed up about 0.5%. The videoconferencing company’s stock has been on a tear this year, rising 226% in 2020, as the coronavirus pandemic forced millions to work remotely.
