Here's how Amazon just passed Exxon to become the fourth-most valuable company

Amazon passed Exxon this morning to become the fourth-most valuable company (and tech company) in the U.S., behind Apple, Alphabet (Google), and Microsoft. As of this writing, Amazon is worth about $362 billion, versus $357 billion for Exxon, according to Yahoo Finance.
