Best Stock to Buy Right Now: Amazon vs. MercadoLibre

The article compares Amazon and MercadoLibre, noting Amazon's $2.5 trillion market cap dwarfs MercadoLibre's $127 billion. In H1 2025, Amazon reported 11% revenue growth to $323 billion and a 48% net income increase to $35 billion, driven by AWS and asset-light e-commerce, with a P/E of 35. Conversely, MercadoLibre achieved faster revenue growth of 35% to $13 billion but saw net income decline 2% to $523 million due to rising expenses and FX losses, yet its stock rose 50% YTD with a P/E of 62. While Amazon shows stronger profit growth and a lower valuation, MercadoLibre's rapid revenue expansion and smaller scale are presented as factors that could enable higher long-term percentage growth, potentially giving it an edge despite its current valuation and profit dip.

Analysis

The comparative analysis of Amazon (AMZN) and MercadoLibre (MELI) reveals a classic growth versus profitability scenario. Amazon, with its nearly $2.5 trillion market capitalization, demonstrated robust bottom-line performance in the first half of 2025, recording an 11% revenue increase to $323 billion but a substantial 48% surge in net income to $35 billion, driven by the profitability of Amazon Web Services (AWS) and operational efficiencies from AI. This performance supports its P/E ratio of 35, which is close to the S&P 500 average. In stark contrast, MercadoLibre, at a much smaller $127 billion market cap, exhibited superior top-line growth, with revenues rising 35% to $13 billion over the same period. However, this growth came at the cost of profitability, as a 38% increase in operating expenses, provisions for doubtful accounts, and foreign currency impacts led to a 2% decline in net income to $523 million. Despite this profit contraction, MELI's stock has appreciated 50% year-to-date, and it trades at a significantly higher P/E multiple of 62, indicating the market is pricing in its long-term growth potential in the Latin American e-commerce and fintech sectors.

Key Decisions for Investors

• Investors must weigh MercadoLibre's superior 35% revenue growth and smaller size, which suggests a longer runway for expansion, against its high 62 P/E valuation and a recent 2% decline in net income.
• Consider Amazon for its demonstrated ability to generate significant profit growth, with net income up 48%, and a more reasonable valuation at a 35 P/E ratio, representing a play on stability and AI-driven efficiencies in a mature market.
• For MercadoLibre, it is crucial to monitor upcoming quarterly results to determine if the surge in operating expenses and pressure on net income are temporary, as the stock's 50% year-to-date rally has been disconnected from its recent bottom-line performance.
• A potential strategy could involve a barbell approach, holding Amazon for its profitable scale and cash flow generation while allocating to MercadoLibre for high-growth exposure to the emerging Latin American digital economy, thereby balancing risk and growth profiles.
