The five biggest tech companies - Amazon, Apple, Alphabet, Facebook, and Microsoft - have lost $ 416.63 billion in a day, CNBC reported

Apple shares fell 9.88%, Facebook - 9.30%, Alphabet - 8.2%, Amazon - 7.98%, and Microsoft - 9.48% as investors continue to worry about the spread of coronavirus and its potential impact on the economy.

By the way, on Monday the five biggest tech companies lost $ 320 billion and then recovered some of these losses during the week.
