Recently, I have been analyzing what is really happening in the Mexican Stock Exchange in 2026, and the truth is there is an interesting movement that many investors are overlooking. The main companies listed on the Mexican stock market are showing surprising resilience, especially considering all the geopolitical noise in the global market.

First, the context: the BMV has only 145 listed companies, so it is a fairly concentrated market. The fascinating thing is that the S&P/BMV IPC, which groups the 35 largest, accounts for about 80% of the total market value. And the five main companies listed on the stock exchange practically define the movement of the entire index.

Let’s talk about the real numbers. Grupo México leads with a market capitalization close to 1.53 trillion pesos, followed very closely by América Móvil with 1.35 trillion. Walmart Mexico is in third position with nearly 957 billion. FEMSA and Fresnillo complete the top 5. Together, these five companies represent almost 50% of the entire market capitalization. When I say they are pillars of the market, I’m not exaggerating.

What’s interesting is that the performance has been mixed but generally positive. So far in 2026, the index has gained about 5-6%, although it moved from highs of 72,000 points in February. But here’s the good part: compared to the S&P 500, which has barely gained 5% in the last 12 months, the S&P/BMV IPC has generated returns of around 22% in the same period. That’s a quite significant performance difference.

Each of the main companies listed on the stock exchange has its own story. Walmart Mexico reported consolidated sales close to 246 billion pesos in the first quarter, although margins are under pressure due to operational costs. América Móvil showed revenue growth of 2.1% but net profit jumped 25.1% year-over-year, suggesting better cost control. Grupo México accelerated revenue by 11% in the latest available quarter with net profit over 50%. FEMSA maintains its solid position although with currency pressures. Fresnillo inherited a spectacular 2025 with revenues of 4,561 million dollars, a 30.5% year-over-year growth.

The mining sector is being the engine, especially because of copper. Basic consumption and telecommunications are also driving forces. The Mexican peso remains in a relatively strong range of 17.30 to 17.80 per dollar, which helps Mexican companies with dollar-denominated debt.

What I find relevant is the contrast. While the Trump administration imposes tariffs and generates volatility, the nearshoring flow continues to be sustained. Mexican domestic consumption resists. And here’s the point: if you have had your entire portfolio in the United States for years, 2026 might be the time to reconsider that. A diversified strategy combining exposure to the main companies listed on the Mexican stock exchange, especially in mining and consumption, plus selectively some U.S. assets, could capture performance differences that are currently quite significant.

Mexico isn’t perfect. Inflation hovers around 4.5-4.6% annually, above Banxico’s target of 3%. There are clear geopolitical risks. But the resilience shown in recent months suggests that the Mexican market has more strength than many assume. If you are looking to diversify or explore new opportunities in less saturated markets, it’s worth reviewing what is happening in the BMV right now.
