Buy These 3 Stocks Now, Hold 20 Years, Retire a Millionaire

You don’t have to make flashy moves in the stock market to generate long-term wealth. Buying and holding companies with solid fundamentals is a successful long-term strategy that lets you build wealth over time without having to monitor your portfolio throughout the day. While you can invest in ETFs for extra portfolio diversification, these three stocks have a shot at generating outsized returns.

Micron

Micron (NASDAQ:MU | MU Price Prediction) is an AI enabler that specializes in memory storage solutions. AI chips need Micron’s technology to process intense workloads, which makes it a critical piece of the AI buildout. As AI infrastructure expands, Micron is poised to deliver exceptional long-term gains.

Investors have already noticed, with the stock more than quadrupling over the past year. While Micron delivered blowout earnings in Q1 FY26, its recently released Q2 FY26 shows substantial momentum. Revenue almost tripled year-over-year, and total sales were up by 75% sequentially. 

Micron also closed the quarter with a net profit margin above 50%. Its $13.79 billion in net income marks a 771% year-over-year improvement. Profits also more than doubled sequentially, highlighting the substantial demand Micron is receiving for its memory storage solutions. That traction sets Micron on a path to becoming a $1 trillion company within the next three years.

Amazon

Amazon (NASDAQ:AMZN) has been a sluggish stock in recent years, underperforming the S&P 500 over the past five years. However, the e-commerce giant’s business has continued to expand in multiple industries. Amazon’s online marketplace has opened multiple revenue streams, including streaming and high-margin online advertising.

However, the big growth engine for Amazon’s future quarters is Amazon Web Services. This cloud platform has benefited from rising AI demand to the point that revenue growth rates are reaccelerating. AWS sales reached $35.6 billion in Q4 2025, marking a 24% year-over-year improvement. 

Amazon is well-diversified and has multiple business segments that are profitable and growing. The company’s immense cash position and ability to generate substantial quarterly profits make it easier for the firm to capitalize on emerging AI opportunities, like its multi-billion-dollar Trainium AI chips. Those investments can translate into elevated returns for long-term shareholders.

Nvidia

Nvidia (NASDAQ:NVDA) is the backbone of the AI boom with its GPU chips second to none. Each quarterly earnings report has been better than the last, and CEO Jensen Huang recently went on record saying that the company expects more than $1 trillion in sales through 2027. 

Not only are Nvidia’s sales figures impressive, but they also come with lofty profit margins. The AI chipmaker’s net profit margins topped 60% in the most recent quarter. If Nvidia earns $1 trillion in 2027 revenue, it will clear more than $600 billion. That’s a lot of cash for reinvestments, buybacks, and dividends.

Now might be the perfect opportunity to buy. Nvidia has been flat for several months despite delivering exceptional results and offering optimistic guidance. Zooming out slightly shows that the stock has gained more than 50% over the past year. It has also surged by over 1,000% over the past five years.
