If you only glanced at the political risk headlines around Grupo México. de, a double digit gain over a year might not be the outcome you would have pencilled in. Investors who held Grupo México. de over the past year are up 51.6%, including dividends. That result landed as revenue and net income in Q3 2026 came in above Q3 2025, with a higher net margin. If that kind of payoff was on the table, what exactly did investors know at the start, and what did they think they were risking?
On Simply Wall St, a Narrative is an investor's thesis written down: the reasoning, plus the numbers it rests on. Run those numbers and you get an estimated Fair Value.
If the move has made Grupo México. de harder to judge, start where the gap is still open and scan 197 high quality undervalued stocks.
At the start of the period, the shares in Grupo México. de cost MX$156. Anyone buying then had to choose between two very different stories that both looked reasonable on the information available.
The bullish narrative put Fair Value at MX$168, or 8% above the start price. It hinged on copper volumes from Peru projects like Tia Maria, ongoing cost reductions and a net cash cost of $0.98 per pound supporting wider margins over time.
The bearish narrative argued for Fair Value of MX$46.15, around 70% below the start price. It treated intensifying political and regulatory risk in Mexico and Peru, including the possibility of asset expropriation and higher taxes, as a central threat to future mining earnings.
The clearest fact in the period was the Q3 2026 report. Grupo México. de booked revenue of US$6,333.016m against US$4,592.138m a year earlier, while net income moved from US$1,285.489m to US$1,984.469m and net margin went from 28.0% to 31.3%. That pattern supported the optimistic case built on stronger volumes and tighter costs, although it did not address political risk.
The useful takeaway is what you test first. When a thesis leans on margin expansion, focus on reported net margin and absolute profit rather than headlines or share price moves at the next commodity cycle swing.
At MX$224, Grupo México trades above the Fair Value that this Narrative estimates, so the Narrative treats the current quote as pricing in a lot of things going right.
The focus is not political risk anymore. It is whether big copper projects and weaker divisions can collectively deliver the earnings profile that today’s valuation seems to lean on.
"The main factor that has to go right is that Grupo México converts its large copper project pipeline and Asarco modernization plans into sustained low-cost production, while Transportation and Infrastructure improve earnings from their current levels."
