The world's five largest technology companies - Amazon, Apple, Alphabet (Google's parent company), Facebook and Microsoft - have lost $ 416.63 billion in combined costs as markets continue to decline due to fears of the Coronavirus epidemic and economic uncertainty.

Apple shares decreased by 9.88%, Facebook shares by 9.30%, Alphabet by 8.2%, Amazon by 7.98%, Microsoft declined by 9.48%, with investors still concerned about the spread of the Corona virus and its potential impact on the economy.

And this decrease, according to the day before yesterday, Thursday, is greater than it was last Monday when the five largest companies together lost $ 320 billion, before recovering some of those losses during the week.

Investors seem to be more concerned about the size of consumers and businesses who will cut spending if the economy enters a recession, and there are additional concerns about supply chain restrictions on manufacturing products. For example, Apple warned in February that it did not expect to meet its second-quarter revenue forecast.

It is not only the weekly figures in the market value that have decreased. Since the beginning of the year, the five companies have witnessed a decrease in their market value as well.

The CNBC news agency report indicates that Facebook's market value decreased by 24.7%, while Google's value decreased by 17%, and Apple witnessed a decrease in its market value by 15.5%, while Microsoft decreased its market value by 11.8% and Amazon increased by 9.3%.
