A vaccine might be good news for the world, but it isn't good news for Zoom. When Pfizer announced its COVID-19 vaccine was more than 90% effective, Zoom's stock instantly plummeted.
And Zoom, which was down more than 11% in premarket trading as of 7:30 a.m. ET Monday, wasn't the only "stay at home" stock to drop. Peloton dropped more than 9%, while Etsy and Netflix were down more than 5%. Even Amazon was hit, with a 1.4% fall. The market movements were a reminder that as the world goes back to normal, tech may face an uphill battle.
