Could MercadoLibre Stock Be a Once-in-a-Decade Buying Opportunity?

MercadoLibre continues delivering strong 49% YoY revenue growth in Q1 2025, but operating margins have halved from 12.9% to 6.9% due to aggressive investments in logistics, fintech expansion, and intensifying competition from Shopee and Temu. Despite near-term profitability concerns, the company's integrated business model, dominant market position, and reasonable valuation (PS multiple of 2.9) may present a compelling long-term opportunity if management successfully converts current investments into stronger margins and free cash flow.
