Amazon shares on Thursday soared past the $800 mark for the first time, closing at an all-time high of $804.70 per share.
That gives Amazon a market cap of over $380 billion — more than twice as much as it was in April 2015, when its shares surpassed $400 for the first time.
Amazon's market cap is now the fourth largest in the world, trailing only Apple, Alphabet, and Microsoft.
Amazon's stock has been on an absolute tear lately. In February, its shares were trading at around $550 when the broader tech market collapsed, and it went across $600 for the first time in October 2015.
Part of Amazon's rise has to do with the company's consistent growth and dominance in both the e-commerce market and cloud computing business. The company last year passed $100 billion in annual revenue for the first time, while keeping up a robust growth rate of about 30% even as the company scales.
Its cloud computing business, Amazon Web Services, is now generating $10 billion in annual revenue with a solid 25% margin. Amazon has also posted record profits for three straight quarters, an anomaly for a company known for investing in growth at the expense of losses.
On top of that, Amazon Prime, its massively loyal paid-membership program continues to expand, while new initiatives in original programming and hardware, like the Echo, keep turning out to be huge successes.
Wall Street seems to expect even more growth. RBC Capital upgraded Amazon's price target to $1,000 in a note published last week, noting strong growth across almost all platforms.
"Amazon's fundamentals have NEVER been stronger in our view," RBC Capital analyst Mark Mahaney wrote.
