2 Stocks Down 26% and 68% to Buy Now and Hold for the Next Decade

MercadoLibre shares are ~26% below their all-time high, but Q2 revenue rose 43% YoY in constant currency, supported by 89M unique active buyers (+26% YoY) and 88M monthly active fintech users (+30%). The article argues margin pressure is the key risk, though advertising revenue grew 70%+ and could support margin expansion. Coupang shares are down ~68% from its 2021 peak after a data breach and slowing growth, yet Q2 revenue still rose 10% YoY on a currency-adjusted basis, with growth potentially reaccelerating as customers return.

Analysis

The market is still pricing these as cyclical growth stories, but the real mechanism is platform compounding: both businesses can turn traffic into payments, credit, logistics, and ads, which raises lifetime value and makes share loss harder than headline revenue growth suggests. For MELI, the second-order winner is the merchant ecosystem around it: as fulfillment and payments tighten, smaller regional e-commerce players and legacy banks/PSPs likely lose checkout relevance and underwriting access over the next 6-18 months. For CPNG, the breach looks more like a trust tax than an existential moat break; the risk is less customer attrition than slower conversion of WOW members into higher-frequency baskets if management over-indexes on recovery spending.

Near term, the key catalyst is not growth versus last year but margin trajectory versus expectations. MELI can absorb reinvestment longer because ad monetization and fintech mix can offset logistics drag; if operating leverage shows up in ads or credit loss rates, the multiple can re-rate faster than revenue alone implies. CPNG is a cleaner “prove-it” story: if product commerce active customers and WOW spend per member accelerate for one or two quarters, the market should begin to discount a normalization of post-breach churn; if not, the stock can stay cheap for a reason.

Contrarian view: MELI may be less of a bargain than it looks if the market starts capitalizing it like a payments/logistics platform rather than an e-commerce name, because reinvestment can suppress GAAP margins for longer than bulls expect. CPNG may be the more asymmetric setup at 0.8x sales, but only if the breach is truly behind it; any renewed cybersecurity issue, regulatory scrutiny, or deceleration in Korea/Taiwan would quickly invalidate the discount thesis. The consensus is probably underestimating how much of both stories depends on execution quality, not just top-line growth.

Key Decisions for Investors

• Long MELI on 1-3 month weakness rather than chasing strength; the setup is a quality compounder re-rating only if ad and fintech mix continue to offset logistics spend. Falsify if revenue growth decelerates materially or operating margin fails to stabilize over the next two quarters.
• Use CPNG as a watchlist long, not an immediate conviction buy: wait for evidence of sustained customer re-engagement and WOW spend re-acceleration before adding. Best entry is after the next earnings print if breach-related churn remains contained and guidance does not get conservative.
• Pair trade: long MELI / short CPNG on a 3-6 month horizon if you want to express “best-in-class ecosystem vs recovery story.” Risk/reward favors MELI if the market starts rewarding monetization quality over cheap sales multiples.
• Alert on CPNG if active customer growth stalls below low-single digits or if Korea consumer spending weakens; that would suggest the breach was a catalyst for a longer competitive reset rather than a temporary hit.
