Amazon.com, Inc. (AMZN) perpetual market

Amazon is a global technology and retail giant founded by Jeff Bezos in 1994, which began as an online bookstore and grew into the largest Western e-commerce marketplace, selling and shipping a vast range of goods and operating a huge logistics network. Its most profitable business, however, is Amazon Web Services, the pioneer and market leader in cloud computing, which rents computing power and services to companies worldwide and generates the bulk of the company's operating profit. Amazon also runs a large advertising business, the Prime subscription program, streaming through Prime Video, devices such as Alexa and Kindle, and the Whole Foods grocery chain. Known for its relentless focus on customer experience, low prices and long-term investment over short-term profit, Amazon reshaped retail, cloud infrastructure and logistics. Now led by Andy Jassy, it remains one of the most valuable companies in the world and a major index constituent.
