From Pariah to Outperformer
When Javier Milei took office on December 10, 2023, Argentina's equity market was priced for collapse. The Merval index had limped through years of capital controls, currency dislocation, and a shrinking economy that saw GDP contract 1.6% in 2023 alone.
What followed was one of the most dramatic reversals in emerging-market history.
By June 2025, the Merval had surged approximately 140% in U.S. dollar terms from its pre-inauguration lows, outperforming every major Latin American benchmark. The rally was not a speculative sugar high driven by retail frenzy; it was underpinned by fundamental repricing. Corporate earnings denominated in dollars surged as inflation-adjusted costs fell, margins expanded, and the policy environment shifted from hostile to merely unpredictable.
> "The Merval rally has been a macro-to-micro story," notes Diego Pérez, chief strategist at Balanz Capital. "First the currency stabilized, then interest rates collapsed, and only then did individual stock stories start to matter."
Anatomy of the Index
The S&P Merval is Argentina's premier equity benchmark, comprising roughly 25 liquid stocks weighted by market capitalization. It is dominated by three sectors: energy, financials, and utilities—a concentration that amplifies both upside and downside.

YPF: The Flagship Bet
No stock encapsulates the Milei trade like YPF S.A. (NYSE: YPF; BCBA: YPFD). The state-controlled oil and gas giant was nationalized in 2012 and languished under populist management for a decade. Milei's government has pursued partial privatization, cost rationalization, and a renewed focus on Vaca Muerta shale development.
YPF's ADR price rose from roughly $13 in late 2023 to over $32 by mid-2025. The company's upstream production is overwhelmingly dollar-revenue; its legacy downstream and refinery inefficiencies are being surgically addressed. For foreign investors, YPF offers the cleanest proxy on Argentine energy and the government's reform credibility.
Risks remain. Labor disputes at Vaca Muerta are chronic, and any delay in privatization could trigger a sharp repricing. Still, YPF's enterprise value trades at a steep discount to global peers on a barrels-of-oil-equivalent basis.

The Banking Complex
Argentine banks were among the worst-performing financial institutions in the world during the 2018–2023 period. Under Milei, they have become redemption stories.
Grupo Financiero Galicia (NASDAQ: GGAL; BCBA: GGAL) and Banco Macro (NYSE: BMA; BCBA: BMA) lead the pack. Both institutions have cleaned up their loan books, reduced exposure to Leliq and other central-bank monetary instruments, and quietly rebuilt dollar-linked lending portfolios.
Galicia trades at roughly 1.3x price-to-book, a discount to regional peers that reflects residual macro risk but also ignores the bank's dominant digital platform and deposit franchise. Macro is cheaper at roughly 1.0x book, but carries a more concentrated shareholder base and higher exposure to SME lending.
> Key Metric: Argentine bank net interest margins (NIMs) compressed sharply in early 2024 as interest rates fell from triple digits, but stabilized in the 8–12% range by mid-2025—still among the highest in the world.

Utilities and Infrastructure
The utility sector presents a more complicated picture. Pampa Energía (NYSE: PAM; BCBA: PAMP) has benefited from tariff rebalancing and dollar-indexed generation contracts, but political sensitivities around residential electricity bills cap the upside. Central Puerto, another power generator, offers a purer play on wholesale electricity pricing and export potential to Brazil and Uruguay.
ADRs: The Foreign Investor's Gateway
For international investors unwilling to navigate Argentina's local custody and settlement infrastructure, American Depositary Receipts (ADRs) provide the simplest access point. The most liquid Argentine ADRs include:
| Ticker | Company | Sector | Primary Listing |
|--------|---------|--------|-----------------|
| YPF | YPF S.A. | Energy | NYSE |
| GGAL | Grupo Financiero Galicia | Financials | NASDAQ |
| BMA | Banco Macro | Financials | NYSE |
| PAM | Pampa Energía | Utilities | NYSE |
| TEO | Telecom Argentina | Telecom | NYSE |
| LOMA | Loma Negra | Materials | NYSE |
Liquidity varies. YPF and Galicia trade millions of shares daily on U.S. exchanges. Loma Negra and Telecom Argentina are thinner, with wider bid-ask spreads that punish impatient capital.
Valuation and the Ceiling
The bull case for Argentine equities rests on a simple arithmetic: the market trades at a forward P/E of roughly 8–9x aggregate earnings, versus 14–16x for Brazil and Mexico. If Milei's reforms deliver even partial convergence to regional norms, the re-rating potential is substantial.
The bear case is equally stark. Inflation remains the highest in the G20 at roughly 25% annualized in mid-2025—down from triple digits, but still corrosive. The fiscal deficit has narrowed dramatically, yet debt rollover risks loom large in 2026–2027. And a political reversal in the 2027 presidential election could unwind deregulation overnight.
> "We're not arguing Argentina has become Switzerland," says María Gutiérrez, portfolio manager at Ashmore Group. "We're arguing the risk premium was so absurdly wide that even modest policy competence created enormous alpha. That alpha may be fading."
Tactical Considerations for 2025
- Dollar-cost averaging suits this market better than lump-sum deployment; volatility is structural, not incidental.
- Sector rotation is likely as the reform story matures; energy and banks led Phase 1, but consumer discretionary and materials may lead Phase 2 if real wages recover.
- Local versus ADR arbitrage occasionally appears due to capital-control remnants and settlement timing; sophisticated investors monitor the "dolar MEP" spread for entry points.
Conclusion
The Merval's rally under Milei has been one of the great emerging-market trades of the decade. It has also been front-loaded: the easiest gains came from collapsing the risk premium, not from organic earnings growth. Investors entering now face a higher baseline and a more demanding macro environment. The opportunity set remains real, but stock selection and entry discipline matter more than ever.
