MercadoLibre Stock Is Down 31%. Should You Buy It Before It Reports Earnings on May 7?

MercadoLibre posted 47% year-over-year revenue growth in its 2025 fourth quarter, with ad revenue up 67% and Mercado Pago interactions increasingly automated by AI. Growth in Brazil accelerated after a lower free-shipping threshold, with gross merchandise volume up 35% and items sold up 45%, but operating and net margins fell, pressuring the stock. Shares are down about 30% from highs and trade at a P/E of 47, near a 10-year low.

Analysis

The market is treating MELI like a margin story, but the more important read-through is that management is intentionally converting near-term earnings into a larger attach-rate ecosystem. In underpenetrated Latin America, that is usually the right trade: once logistics, payments, and merchant tooling are integrated, the winner tends to compound share faster than the market model assumes. The AI-driven efficiency gains matter less as a cost line item and more as a force multiplier that widens the moat in ads, payments, and merchant conversion simultaneously.

The first-order selloff likely reflects investors extrapolating a single quarter of margin compression into a structural reset. That’s probably wrong if unit economics are still improving in the underlying cohorts, because higher shipping thresholds and broader assortment usually create a temporary margin drag before they generate higher basket sizes, repeat frequency, and ad monetization. The second-order winner here is not just MELI equity holders; it is also local SMBs and merchants that become more dependent on MercadoLibre’s traffic and financing rails, making competitive displacement harder for regional e-commerce and digital wallet challengers.

The setup into earnings is asymmetric: downside is constrained if management merely confirms that investment spend is being sequenced and cohort quality remains intact, while upside can be sharp if the market sees evidence that the margin dip is transitory rather than permanent. The true risk is not next quarter’s EPS; it is a broader LATAM consumer slowdown or FX shock that forces the company to spend even more to defend share. Consensus appears to be overreacting to the profit dip and underpricing the durability of the operating leverage that should emerge once recent investments mature.

For trade structure, this looks better as a long volatility/event-driven setup than a naked directional hold into the print. If the company can show stabilization in contribution margins or clearer monetization of AI-led traffic, the re-rating could happen quickly because positioning is likely lighter after the drawdown. If not, the stock may stay range-bound, but the long-term bull case remains intact as long as share gains continue.

Key Decisions for Investors

• Buy MELI into earnings on weakness, sized for a 3-6 month hold; the risk/reward favors owning the high-quality compounder while expectations are depressed, with upside if margin stabilization is even modestly better than feared.
• Use a call spread on MELI for the next earnings cycle (e.g., 1-2 month tenor) to express a post-print rebound; this limits downside to premium while keeping exposure to a sharp rerating if bottom-line guidance improves.
• If already long MELI, hedge with a tight short-dated put spread rather than selling stock; the market is pricing in margin disappointment, so defined-risk downside protection is preferable to exiting a long-duration winner.
• Consider a relative-value long MELI / short a basket of higher-multiple regional e-commerce or fintech peers over 1-2 quarters; MELI’s ecosystem depth and monetization optionality should outperform if LATAM consumer demand remains resilient.
• Do not short MELI purely on the headline margin compression; the better risk/reward short would require evidence of cohort deterioration or FX-driven demand weakness over the next 1-2 quarters, not just one investment-heavy print.
