However, Amazon's long-term future looks bright. Some investors have been put off by management's decision to invest heavily, particularly in areas like data centers, to meet growing demand for generative artificial intelligence. However, given the vast growth potential and Amazon's No. 1 market position in cloud computing via its Amazon Web Services (AWS) business, it looks like an astute investment.

AWS is already growing quickly, with a 36.8% year-over-year gain in second-quarter sales to $42.2 billion. It's also the company's largest profit generator, accounting for 60.5% of operating income.

Looking at the entire company, Amazon's second-quarter sales grew 20% year over year to $200.6 billion. Operating income increased by more than 43% to $27.5 billion.

You shouldn't invest solely based on someone's holdings, even someone as astute as Bezos. However, given management's commitment to long-term growth and patient investing, Amazon belongs in your portfolio . It may not make you a billionaire, but it should allow you to grow your wealth over time.
