Top 3 Long-Term Stocks to Hold for 20 Years

MercadoLibre reported 45% y/y revenue growth in Q4, serves 121M unique buyers and 78M MAU on Mercado Pago, with a $90B market cap and current price of $1,764.30, highlighting strong fintech and e-commerce expansion in Latin America. Lululemon has delivered a 19% CAGR over the last decade but slowed to 7% y/y in the latest quarter; market cap $446B, price $1,004.16, gross margin 13.6% and a 0.52% dividend yield, with international (China) representing 18% of fiscal Q3 revenue. Costco reached 81M paid members in fiscal 2025 (membership growth 6.2%), operates 633 U.S./PR warehouses and 923 worldwide, signaling durable, membership-driven retail growth with international expansion runway.

Analysis

MercadoLibre’s payments + marketplace coupling creates a multi-layered moat, but the real optionality is in financial intermediation becoming a quasi-bank for underbanked consumers. That path generates high ROIC long-term, yet it also converts business-model risk into regulatory and liquidity risk: if regulators treat deposits or credit products more like banking liabilities, capital intensity and funding costs can rise materially over a 12–36 month horizon. FX volatility in LatAm is a live tail-risk that can amplify P&L swings even as local-currency volumes grow.

Lululemon’s brand-driven premium positioning gives it pricing optionality, but the marginal growth lever is geographic penetration and category expansion—both expensive and margin-sensitive. Inventory fashion cycles and a higher-end consumer spending beta mean a macro swing (growth slowdown or RMB weakness) could compress multiple points of margin inside a single year. Competitors in technical apparel and fast-fashion incumbents will increasingly weaponize price/promotions to slow share gain outside core markets, pressuring near-term comps.

Costco is the defensive structural play: the membership flywheel reduces churn risk and supports cash flow in soft consumption regimes, but international rollouts and real-estate lead times cap growth elasticity. The second-order effect is on suppliers—Costco’s scale forces suppliers to rationalize packaging/logistics, advantaging large CPGs and squeezing niche suppliers. If inflation normalizes, Costco’s margin mix could tilt back toward discretionary, creating a modest upside to earnings power over 12–36 months.

Across the three, the consensus underprices funding/regulatory risk in fintech and overprices near-term international expansion for retail names. Positioning should favor asymmetric optionality in MELI’s fintech upside with defined downside protections, rotate duration away from pure growth multiple risk in LULU, and use COST as a ballast that monetizes membership durability while harvesting income via covered calls.

Key Decisions for Investors

• Long MELI convexity via options: Buy MELI Jan-19-2028 LEAP calls (2-year) and finance with short-dated calls (sell 3–6m calls) to reduce premium. Add a 6–12m USD/BRL hedged position (sell BRL forward or buy USD/BRL call) to cap FX-driven drawdowns. Risk/reward: limited to premium paid (plus short-call assignment risk) vs. 2–4x upside if fintech monetization and credit expansion scale over 24+ months.
• Pair trade: Short LULU / Long COST (equal notional) for 6–18 months to capture rotation from premium apparel into defensive membership retail. Use a 10–15% stop on the short leg and trim at +20% P&L on the pair. Expected payoff: 15–25% relative gain if consumer tone softens or LULU multiple compresses while COST holds membership resilience.
• Income overlay on COST: Buy shares of COST and sell 1-year covered calls (out-of-the-money) to enhance yield while keeping upside. Target net yield pickup of 2–3% annualized; downside protected modestly by option premium but set mental stop at -12% absolute for capital preservation over 12–24 months.
• Defensive hedge: Buy broad consumer-cyclical puts (e.g., long-dated SPX or XLY put spread) for 9–12 months sized to cover 20–25% of gross exposure to LULU and other premium retail names. Cost of hedge should be viewed as insurance against a macro drawdown that would disproportionately hurt high-beta consumer discretionary names.
