Investors can find success in the stock market by sticking with companies that consistently report strong growth in revenues. This is a simple strategy that, when applied across a diversified portfolio of growth stocks, can lead to outstanding returns over a decade or more.
The important thing is to follow the growth of the business, not the short-term volatility in the share price. There's a high correlation between a company's growth and stock performance over many years.
With that in mind, let's look at two stocks that could be easy wealth builders for a long-term investor.

1. MercadoLibre
The Latin American e-commerce market is booming. It is a large population surpassing 650 million people, which is fueling strong growth for MercadoLibre (MELI +0.43%). The company offers an online marketplace where merchants can sell goods to millions of buyers, but it also generates revenue from mobile payments, advertising, and other fintech services.
Over the last 10 years, the company's revenue has grown at a compound annual rate of more than 40%, sending the stock up 2,000%. MercadoLibre continues to report high rates of growth as it continues to invest in improving the customer experience, such as lowering prices, increasing shipping speeds, and rolling out new products like credit cards. Revenue reached nearly $6.8 billion in its second quarter 2025, representing a year-over-year increase of 34%.

Key Data Points
MercadoLibre has multiple levers to pull to sustain high rates of growth. It recently reduced shipping and seller fees, incentivizing sellers to also reduce their selling prices. This move shows how it is leveraging its massive scale as the dominant e-commerce company in Latin America to gain share and grow its customer base.
Lower fees for sellers are expected to increase the selection of goods offered on the marketplace, which, in turn, will drive higher customer satisfaction and more frequent shopping.
Additionally, the Mercado Pago credit business has been a fast-growing source of revenue in recent years and an attractive long-term opportunity to win more customers. The company's credit portfolio roughly doubled in Q2 over the year-ago quarter, indicating strong adoption of its credit card product.
The integration of financial services like credit cards, paired with its commerce business, helps create a tighter ecosystem of services that drives customer loyalty. With just 68 million monthly active users, MercadoLibre has an enormous runway to grow its fintech business.
MercadoLibre is tapping into a huge opportunity, helping millions of people in the region get access to basic financial services. The compounding growth of this business makes it an excellent buy-and-hold stock to build wealth for retirement.
2. Coupang
Coupang (CPNG +2.83%) has a lot of similarities to Amazon. It is revolutionizing e-commerce in South Korea and Taiwan, where it's showing strong growth potential outside its home market in Korea. It might seem challenging for another e-commerce juggernaut to rise under Amazon's shadow, but Coupang has advantages.
Coupang's trailing-12-month revenue has increased 62% over the three years to $32 billion. Quarterly revenue increased by 19% year over year in Q2 on a constant-currency basis. The company's profitability also continues to trend in a positive direction, with gross profit, operating income, and earnings per share increasing over the year-ago quarter. Strong financial results pushed the stock up 30% year to date.
NYSE: CPNG
Key Data Points
This growth reflects execution at expanding product selection, and investing in automation to improve delivery speed. It offers same-day delivery across a massive selection of products to millions of customers living in densely populated cities, which is the basis of its competitive advantage.
One area of the business that indicates a lot of growth potential is its Developing Offerings. This includes grocery delivery and streaming entertainment. Revenue from these items grew 33% year over year -- significantly faster than its product commerce. This reflects more customers continuing to spend more with Coupang after initially purchasing products through its e-commerce business.
Moreover, management indicated in the last earnings report that its Developing Offerings in Taiwan are growing faster than anticipated. This is a great sign that its business model could find more markets outside of South Korea, where it can be successful and deliver returns for shareholders.
Coupang is essentially becoming the default app that 24 million active customers rely on for buying goods, food, and digital entertainment. Its record of consistently reporting high-double-digit growth, with promising international expansion potential, could make this a huge winner for investors over the long term.
