After reaching a $1 trillion market value Jan. 31, Amazon's shares closed with a total value of $999.96 billion, according to The Wall Street Journal.
Amazon's shares dipped due to negative sentiment that caused a late-day market selloff. The last time Amazon reached the $1 trillion valuation was in September 2018. The company, for a moment, joined Alphabet, Apple and Microsoft in the $1 trillion club.
The company's value topped the $1 trillion mark after an impressive fourth quarter financial report, which was led by huge growth in revenues from the Amazon Web Services cloud platform. AWS saw a 34 percent year-over-year increase for the quarter, and a 37 percent increase for the year.
