Investing in Latin America: Brazil, Mexico, Chile, Colombia, Peru and Argentina compared
What each of the region's stock markets offers, which sectors dominate, how the currency matters and how to combine them in a portfolio.
Oct 22, 2026 · 4 min read
Latin America has more than 600 million people, vast natural resources and some of the best-known companies in the emerging world. Yet its stock markets are very different from one another. Investing in "Latin America" isn't one single thing: it means combining markets with their own currencies, sectors and risks.
In this guide we compare the six main markets and show you how to explore them in the tool.
A quick overview

|---|---|---|---|---|
| Brazil | Ibovespa | Oil, mining, banks | Real (BRL) | View |
| Mexico | S&P/BMV IPC | Consumer, telecoms, banks, airports | Peso (MXN) | View |
| Chile | S&P IPSA | Banks, retail, lithium, energy | Peso (CLP) | View |
| Colombia | MSCI COLCAP | Oil, banks, energy | Peso (COP) | View |
| Peru | S&P/BVL | Mining, banks | Sol (PEN) | View |
| Argentina | S&P Merval | Banks, energy, utilities | Peso (ARS) | View |
Brazil: the region's giant
Brazil's stock exchange (B3) is the largest and most liquid in Latin America. Its index is heavily influenced by Petrobras and Vale, which makes it sensitive to the price of oil and iron ore. Big banks such as Itaú and Bradesco, and industrial companies such as WEG and Embraer, round out the picture.
What to know: the real is a volatile currency. For someone measuring in dollars, a strong run in the stock market can be wiped out by a devaluation, or amplified by an appreciation.
Mexico: consumers and a neighbor to the US
Mexico's stock market is more tied to consumer companies (Walmart de México, FEMSA, Bimbo), telecoms (América Móvil), banks (Banorte) and airports. Its proximity to the United States means many companies depend on trade and tourism.
What to know: the Mexican peso is one of the most traded emerging-market currencies in the world. That gives it liquidity, but also exposes it to sharp moves when global risk appetite shifts.
Chile: banks, retail and lithium
The IPSA combines solid banks, large retailers with a regional footprint (Falabella, Cencosud) and natural-resource companies, among them SQM, one of the world's leading lithium producers.
What to know: Chile's economy is closely tied to copper. When the metal falls, both the stock market and the Chilean peso tend to suffer, doubling the effect for a foreign investor.
Colombia: a small, concentrated market
Colombia's stock market has few large companies: Ecopetrol, Grupo Cibest (Bancolombia's holding company), ISA and Grupo Energía Bogotá, among others. By global standards it's an illiquid market.
What to know: because it's concentrated in oil and banks, investing only in Colombia offers little diversification. Many people use the Ecopetrol or Bancolombia ADRs in New York, or a country ETF.
Peru: mining and finance
The Lima Stock Exchange is dominated by mining (Buenaventura, Southern Copper, Cerro Verde) and by Credicorp, the country's largest financial group.
What to know: the Peruvian sol has historically been one of the region's most stable currencies, but the local stock market is small. Credicorp and Southern Copper also trade in the United States.
Argentina: high risk, high volatility
The Merval brings together banks (Galicia, Macro), energy (YPF, Pampa, TGS) and utilities. It's one of the most volatile markets in the world, because of inflation and frequent changes in economic policy.
What to know: measured in Argentine pesos, the Merval can show huge gains that actually reflect inflation. Measured in dollars, the story changes completely. In the optimizer, try the same portfolio with ARS as the base currency and then with USD to see the difference.
ADRs: the most common way in
Many of the region's largest companies also trade in New York as ADRs (for example Petrobras, Vale, Itaú, América Móvil, SQM, Credicorp, Ecopetrol or YPF). For many investors they're the simplest way to access these markets in dollars. We explain them in detail in what are ADRs. In the explorer you can see them all with the Latin American ADRs shortcut.
How to combine them
The six markets share some traits: a heavy weight in commodities and banks, currencies that tend to weaken together during global stress, and relatively high correlations with one another. That means a Latin America-only portfolio diversifies less than it seems.
Some ideas to consider:
- Mix sectors: combining a Peruvian miner with a Mexican consumer company diversifies more than two banks.
- Mix with other regions: adding the United States, Europe or Asia usually lowers total risk more than adding another Latin American country.
- Cap the regional weight: in the optimizer you can set a limit such as "at most 30% in Latin America".
Try it
The "Latin America" sample portfolio includes ADRs from all six countries plus MercadoLibre. Calculate it, check the correlation map and notice how much they move together. Then add a global ETF and compare.
In short
Each Latin American market has its own personality: Brazil is large and tied to commodities; Mexico, to consumers and the United States; Chile, to copper and lithium; Colombia and Peru are small and concentrated; Argentina is the most volatile. Combining them helps, but combining them with the rest of the world helps even more.
