Tech megacaps lose $770 billion in value as Nasdaq suffers steepest drop since April

- Nvidia, Amazon and Tesla all fell by about 5% on Friday, pushing the Nasdaq down 3.6%, its worst day since April.

- The slide came after President Trump threatened to slap a “massive increase of Tariffs” on Chinese products imported into the U.S.

- Trump later declared that the U.S. would impose a 100% tariff on China and, on Nov. 1, would apply export controls “on any and all critical software,” pushing the technology stocks lower after hours.
