MercadoLibre Rises 47% YTD: Should You Buy, Sell or Hold the Stock?

MercadoLibre's MELI shares have significantly outperformed the market YTD, driven by strong growth in e-commerce and fintech revenues (up 32.3% and 43.3% year-over-year, respectively) and expansion into streaming via the Mercado Play app. However, investors should note headwinds including declining profitability in its credit portfolio, with Net Interest Margin After Losses (NIMAL) falling to 22.7%, and increasing competition from Amazon, Walmart and Alibaba, which could pressure long-term growth and profitability, leading to a hold rating.

Analysis

MercadoLibre (MELI) has demonstrated significant stock outperformance year-to-date, returning 47.4%, substantially exceeding the Zacks Retail-Wholesale sector's 0.5% growth and the S&P 500's 1.9% decline. This robust performance is attributed to its dominant market position in Latin America, a diversified business model spanning e-commerce and fintech, and two consecutive better-than-expected earnings reports. In the first quarter of 2025, total revenues were propelled by a 32.3% year-over-year increase in commerce revenues and a 43.3% year-over-year rise in fintech revenues. Key user metrics also showed strong growth, with Unique Active Buyers up 25% and fintech Monthly Active Users increasing by 31%. Further expanding its ecosystem, MELI launched the Mercado Play app on smart TVs across Latin America, aiming to enhance its advertising inventory by offering over 15,000 hours of free content to a region where fewer than half the population subscribes to paid streaming. Analyst sentiment reflects this positive momentum, with the Zacks Consensus Estimate for second-quarter 2025 earnings revised upward by 12.28% over the past 30 days to $11.70 per share, implying 11.64% year-over-year growth, and revenues projected at $6.37 billion, a 25.52% year-over-year increase. However, significant headwinds temper this outlook. The company's credit portfolio profitability experienced a sharp decline in Q1 2025, with Net Interest Margin After Losses (NIMAL) falling to 22.7% from 31.5% a year prior, primarily due to a structural shift towards lower-return credit cards (now 42% of the portfolio versus 35% YoY) and a move upmarket in lending that erodes yield. This margin compression occurred despite Argentina's higher-margin portfolio share doubling. Valuation also presents a concern, with MELI's forward 12-month Price/Sales ratio at 4.32, notably above the industry average of 2, and a Value Score of D, signaling potential overvaluation. Intensifying competition from global giants like Amazon, Walmart, and Alibaba, which are aggressively expanding in Latin America with substantial resources and advanced logistics, poses a considerable threat to MELI's market share, user retention, and pricing power.

Key Decisions for Investors

• Investors should maintain a hold position on MELI, balancing its strong growth and user expansion against significant headwinds from declining credit margins and intensifying competition.
• Monitor MercadoLibre's Net Interest Margin After Losses (NIMAL) closely in subsequent quarters, as continued deterioration could significantly impact profitability and investor sentiment.
• Evaluate the company's strategies to counter competitive pressures from Amazon, Walmart, and Alibaba, particularly focusing on market share retention and pricing power in key Latin American markets.
• Given the premium valuation indicated by a P/S ratio of 4.32 and a Value Score of D, consider waiting for more clarity on margin stabilization and competitive positioning before initiating or adding to positions.
