Goldman Sachs downgrades Grupo Mexico stock to Neutral on reduced upside

Goldman Sachs downgraded Grupo Mexico (BMV:GMEXICOB) from Buy to Neutral, lowering its price target to 130.00 pesos from 135.00 pesos, citing the stock's significant 58% year-to-date outperformance and a materially reduced NAV price asymmetry relative to Southern Copper. The firm noted that management's commitment to solely invest in its core business alleviated prior capital allocation concerns, contributing to a substantial narrowing of Grupo Mexico's holding discount to 37% from 56% in mid-2024.

Analysis

Goldman Sachs has downgraded Grupo Mexico to Neutral from Buy and reduced its price target to 130.00 pesos, primarily as a valuation call following significant share price appreciation. The stock has outperformed, rising 58% year-to-date in U.S. dollar terms, substantially more than Southern Copper Corporation's 21% gain. This rally was fueled by management's commentary during the Q2 2025 earnings call, where they committed to "solely pursue investment in its core business," which alleviated market concerns regarding capital allocation into non-core assets. Consequently, the holding company discount has narrowed significantly from a high of 56% in mid-2024 to 37% at present. According to Goldman Sachs's analysis, this current discount is now in line with the 10-year historical average, suggesting that the valuation asymmetry that previously presented a compelling investment case has materially diminished.

Key Decisions for Investors

• Investors who have benefited from the 58% year-to-date rally should consider that the primary driver for outperformance—the closing of the valuation gap—has now largely materialized, suggesting a re-evaluation of the position.
• The downgrade to Neutral indicates a more balanced risk-reward profile, and prospective investors should exercise caution as the significant upside seen earlier in the year appears limited at current valuation levels.
• Monitor the holding company discount relative to its historical 37% average; a significant widening could signal a new entry point, while a further narrowing would reinforce the current neutral thesis.
• Closely track management's adherence to its stated capital allocation strategy focused on core assets, as any deviation could reintroduce risks that previously widened the valuation discount.
