MercadoLibre's Margins Are Falling - And That's Bullish

MercadoLibre is rated BUY, as I see short-term margin compression as a strategic investment for long-term ecosystem dominance. MELI's Q1'26 revenue surged 49% YoY, driven by robust growth in both Commerce (39%) and Fintech (54%) segments, despite operating margin dropping to 6.9%. Margin pressure stems from aggressive credit expansion, lower free shipping thresholds, targeted take rate cuts, and heavy 1P inventory investment.
