MercadoLibre stock is down right now, but it has massive long-term opportunities.

Walmart stock is a defensive play, and it's crushing the market right now.

  • 10 stocks we like better than MercadoLibre ›

The market had one of its inevitable dips when oil prices soared before the recent Iran war ceasefire. It's on its way back up, and the S&P 500 is roughly flat year to date. However, the ceasefire looks fragile, and the markets will be sensitive to continued oil volatility.

While investors might choose to stay out of the markets when there's volatility, that's not necessarily the right path for everyone. It could be a great opportunity to buy top stocks on the dip, and it could also be an opportunity to scoop up shares of great protective stocks if you don't have them, or enough of them, in your portfolio.

If you have $1,000 availble to spend and need either one, I recommend MercadoLibre (NASDAQ: MELI) as a top stock to buy on the dip, and Walmart (NASDAQ: WMT) as an excellent asset to own in periods of volatility.

1. MercadoLibre: Huge opportunities in e-commerce and fintech

MercadoLibre operates an e-commerce platform similar to Amazon and serves 18 countries in Latin America. This is a region that's still underpenetrated in e-commerce, and the company is constantly improving its value proposition to boost the shift to online shopping.

It's working, and the company continues to add active customers at a rapid pace, as well as generate higher gross merchandise volume and everything that comes along with the shift, like increased items per buyer and higher purchase frequency. Even better, the region still lags other countries, giving MercadoLibre a wider opportunity.

It's a similar situation with fintech. Management notes that its region has been "poorly served by the traditional financial system," if at all, and MercadoLibre's digital wallet has become massively popular. Less than 20% of the population in Mexico has a credit card, and less than 40% of the Argentine population has one. MercadoLibre is harnessing the opportunity with an easy-to-use platform that goes around the traditional system.

MercadoLibre took a hit to profits in the fourth quarter with some heavy investments, and the stock was down 12% this year. That presents an opportunity to buy on the dip, although with $1,000, you can only buy fractional shares.

2. Walmart: The discount supermarket model

Walmart stock, on the other hand, is up almost 14% this year, crushing the market. Walmart, as a discount retailer, is a defensive play. When there's a recession, people rely on it even more. However, it's really an all-weather stock. It's the largest physical retailer of its kind, with an unmatched 5,000-plus store base, and it's increasingly reaching more types of shoppers.

For example, it has shifted its merchandise lines to comprise healthier and more upscale options, which attracts a more affluent consumer who may not have shopped at Walmart in the past. The e-commerce business reinforces that by offering a larger selection of products than what's available in the brick-and-mortar stores. E-commerce has been a major growth driver, up 24% year over year in the fiscal 2026 fourth quarter.

Walmart is also a Dividend King, which makes it reliable as an anchor stock that offers value no matter what's happening in the stock market at any moment. Walmart is the kind of stock that provides safety in challenging times and value at all times.

Opening Takes

▬ Neutral

"WMT at ~35x forward P/E is not a traditional defensive stock — it's priced like a growth compounder, and the article's 'safety' framing obscures meaningful downside if that multiple compresses."

The article pairs two structurally different plays — MELI as a growth-on-dip bet and WMT as defensive anchor — but glosses over critical risks for each. MELI's Q4 profit hit wasn't a one-quarter blip; management is in a heavy investment cycle competing against Amazon's Latin America push and local players like Mercado Pago rivals. The 12% YTD decline reflects real margin compression, not just noise. WMT at ~35x forward P/E (earnings multiple relative to projected profits) is priced for perfection — calling it 'defensive' ignores that it's trading at a growth-stock valuation. The article also invents a geopolitical backdrop ('Iran war ceasefire') that I cannot verify as a real recent event — readers should flag that framing.

Devil's Advocate

MELI's investment cycle could compress margins further for 2-3 more quarters, making the 'dip' a falling knife rather than a buying opportunity. WMT's premium valuation means any macro softening that pressures consumer spending could trigger a sharp de-rating despite its defensive reputation.

"The article ignores that MercadoLibre's 'dip' is tied to systemic currency volatility and Walmart's 'safety' comes at a historically high valuation premium."

The article frames MercadoLibre (MELI) as a 'dip' play, but ignores the currency devaluation risks inherent in its primary markets, Argentina and Brazil. While MELI's fintech arm (Mercado Pago) is a juggernaut, the 12% YTD drop reflects margin compression from aggressive logistics spending and high-interest-rate headwinds in Latin America. Conversely, Walmart (WMT) is trading near all-time highs with a forward P/E around 25x—expensive for a grocery-heavy retailer. The 'defensive' label is priced in, leaving little room for error if consumer spending shifts from essentials back to discretionary elsewhere. I am neutral because MELI's growth is offset by FX risk, and WMT's valuation offers limited upside.

Devil's Advocate

If Latin American central banks pivot to aggressive rate cuts faster than the Fed, MELI's credit business could see an explosive margin expansion that justifies its premium valuation.

"MercadoLibre's mix of underpenetrated e-commerce and fintech across 18 Latin American countries makes it the more compelling long-term buy here, but expect high volatility from FX, macro, and regulatory risks."

MercadoLibre (MELI) is the higher-return but higher-risk pick here: it combines underpenetrated Latin American e-commerce (operating in 18 countries) with fast-growing fintech adoption — the article notes <20% credit-card penetration in Mexico and <40% in Argentina — giving a large addressable market for payments, credit and marketplaces. Recent investments pressured Q4 profits and the stock is down ~12% YTD, making accumulation on dips sensible for patient investors. Counterbalance: Latin America brings currency volatility, inflation, political/regulatory risk, and competitive/credit risks that can swamp growth; Walmart (WMT) is a safer, income-generating anchor (5,000+ stores, e-commerce +24% YoY) but offers less upside.

Devil's Advocate

If a regional recession, sharp FX devaluation, or tighter fintech regulation hits, MELI's unit economics and loan book could deteriorate and turn this 'dip' into a multi-year value trap. Meanwhile, Walmart's defensive positioning and dividend could outperform, limiting MELI's near-term gains even if the market opportunity is real.

"WMT's proven resilience and e-comm momentum make it the superior $1,000 pick over risk-laden MELI in volatile oil-tied markets."

The article hypes MELI as a dip buy (down 12% YTD) for LatAm e-commerce/fintech growth in underpenetrated markets like Mexico (<20% credit card ownership) and Argentina (<40%), but omits brutal macro risks: Argentina's economic meltdown with currency controls and inflation eroding profitability, as seen in Q4's investment-driven profit hit. WMT's 14% YTD gain, 24% e-comm surge (FY26 Q4), and Dividend King status make it a true defensive anchor amid fragile oil ceasefire volatility. For $1,000, WMT allocation prioritizes stability over MELI's high-beta gamble.

Devil's Advocate

MELI has consistently grown active customers, GMV, and items/frequency despite LatAm turbulence, positioning it to capture decades of penetration upside that U.S. giants can't touch.

Responding to Grok
Disagrees with: Grok

"WMT's e-commerce growth is margin-dilutive, undermining its 'defensive anchor' framing just as much as MELI's investment cycle undermines its 'dip buy' framing."

Grok cites WMT's '24% e-comm surge (FY26 Q4)' as a bullish signal, but that number needs context: Walmart's e-commerce is still largely unprofitable, subsidized by its physical store margin. A 24% revenue jump that bleeds margin isn't a defensive anchor — it's a growth bet wearing defensive clothing. Nobody's flagged that WMT's e-commerce investment cycle could actually converge with MELI's margin compression problem, making both stocks simultaneously expensive and margin-pressured.

Responding to Claude

"The transition to high-margin retail media networks is the primary catalyst being overlooked by the focus on logistics and macro volatility."

Claude is right to question Walmart’s e-commerce margins, but everyone is ignoring the 'advertising' pivot. WMT’s Connect and MELI’s Mercado Ads are now high-margin software businesses (70-80% margins) hidden inside retail shells. If these ad-tech segments continue growing at 20-30%, they decouple both firms from logistics costs. The real risk isn't just margin compression; it’s whether high interest rates break their consumer credit books before the ad-revenue scale kicks in.

"Ad‑tech revenue for MELI and WMT is materially vulnerable to privacy/regulatory and measurement headwinds that could cut ARPU and margins."

Gemini, the ad pivot thesis understates regulatory and measurement risk: deprecation of third‑party cookies, tightening privacy laws (EU and potential US action), and walled‑garden attribution limits can sharply reduce ad targeting effectiveness and ARPU. High‑margin 'software' narratives assume stable data monetization; if regulators force stricter consent or attribution constraints, both Mercado Ads and Walmart Connect could see higher CAC and lower margins—undermining the decoupling from retail logistics.

"Walmart's substantial Mexico operations expose it to MELI-like LatAm macro risks, diluting its defensive appeal."

ChatGPT rightly highlights ad regulatory headwinds, but everyone's missing Walmart's LatAm tether: Walmart de México y Centroamérica (Walmex) drives ~7% of global sales (FY24 data), facing identical Argentina/Brazil-style FX volatility and inflation as MELI. This correlated risk makes WMT less of a 'defensive anchor' than advertised, especially if regional contagion hits consumer staples demand.
