Everyone Is Talking About SpaceX. Here Are 2 Growth Stocks I Like Much Better.

MercadoLibre posted 49% year-over-year revenue growth in Q1 2026, with unique active buyers up 26%, fintech monthly active users up 29%, and total payment volume up 50%. On Holding reported 26% currency-neutral sales growth in Q1 2026, with gross margin expanding to 64.2% from 59.9% and profit margin widening to 12.4% from 7.8%. The article is a bullish comparison piece favoring MELI and ONON over SpaceX, citing stronger fundamentals and more attractive valuations.

Analysis

The important read-through is not simply that both names are “good growth stocks,” but that capital is rotating toward profitability with visible operating leverage. MELI’s underpenetrated ecosystem means each point of take-rate or wallet-share gain compounds across commerce, payments, and credit, so the market is effectively paying for a multi-year monetization runway rather than current earnings. ONON is the cleaner near-term margin story: sustaining full-price sell-through in a soft consumer backdrop signals brand elasticity, which usually precedes broader distribution wins and higher shelf space, not just better quarterly EPS.

Second-order effects matter. MELI’s push into credit is the main hidden option value, but it also creates the most fragile part of the story: delinquency and funding costs can lag growth by several quarters, so the stock can look cheap right before loss provisioning inflects. ONON’s premium positioning is a moat only if it avoids over-distribution; the next leg higher depends on preserving scarcity while expanding, otherwise the margin expansion can revert quickly if discounting creeps in.

The contrarian angle is that both names may be benefitting from a quality-growth rerating, while the market is still treating them like isolated consumer winners. That rerating can persist for months if rates stay stable and earnings revisions continue upward, but it becomes vulnerable if the market rotates back toward cyclicals or if the consumer weakens and forces promotion. In that sense, the best setup is not chasing momentum outright, but owning these as relative-strength beneficiaries versus lower-quality retail and fintech peers.

For MELI, the biggest catalyst is continued operating leverage in payments and credit with no visible deterioration in asset quality; for ONON, it is evidence that U.S. penetration can rise without margin compression. If either company shows even modest slippage in gross margin or credit metrics, the de-rating could be sharp because both are priced on durability, not just growth.

Key Decisions for Investors

• Go long MELI on 3-6 month time horizon; add on any post-earnings pullback that is driven by margin noise rather than buyer/payment growth. Risk/reward favors holding through near-term earnings volatility for the next 12-18 months if credit quality remains stable.
• Go long ONON as a quality-growth compounder for 6-12 months; best entry is on broad retail weakness, with a tight thesis that premium sell-through preserves gross margin expansion. Stop if promotional intensity starts to rise materially.
• Pair trade: long MELI / short a lower-quality LatAm e-commerce or fintech proxy. The thesis is that MELI’s ecosystem monetization is more durable and should capture multiple expansion if sector sentiment improves.
• Pair trade: long ONON / short a large-cap athleticwear incumbent. ONON’s premium pricing and younger-customer gains offer better margin expansion potential, while incumbents are more exposed to discounting and slower share gains.
• Avoid shorting either name outright; the upside is driven by operating leverage and rerating, and short interest is vulnerable to upward estimate revisions over the next 1-2 quarters.
