Amazon closed down 7.82 percent on Friday, a day after a disappointing third-quarter earnings report.

While the e-commerce giant beat predictions on earnings per share, it missed on revenue, reporting $56.6 billion versus $57.10 billion analysts anticipated in a survey by Refinitiv. The drop represents a $70 billion loss in market cap, allowing Microsoft to pass Amazon in market cap.
