US vs Europe: Why the Case for American Stocks Just Strengthened

The April 7 ceasefire between the United States and Iran triggered a capital reallocation of historic proportions. $28 billion in net inflows poured into US equity funds in the days following the truce, reversing months of outflows that had reached $56 billion year-to-date before the announcement. President Trump’s declaration that the Strait of Hormuz crisis had ended sent a clear signal to global investors: the risk-off trade was over, and capital was coming home.

The speed of the reversal startled even seasoned strategists. $23 billion of the $28 billion inflow came from domestic US investors who had rotated into international markets during the conflict. By mid-April, cumulative net outflows from US equities stood at just $30 billion, roughly one quarter of the $56 billion peak reached in mid-March, according to LSEG and Lipper data.

The S&P 500 now trades approximately 2% above pre-conflict levels, outperforming most global indices that merely recovered their war-related declines. The index’s resilience during the crisis and its surge following the ceasefire have reignited a debate Wall Street thought it had settled: US versus European stocks.

TINA vs TIARA: Understanding the Investment Thesis Battle

For years, institutional investors operated under a simple framework: There Is No Alternative (TINA). The thesis held that US equities offered superior risk-adjusted returns compared to any other major market, driven by earnings growth, innovation leadership, and deep capital markets.

Then came January 2025 and the start of Donald Trump’s second presidential term. A competing thesis emerged: There Is A Real Alternative (TIARA). Proponents pointed to dollar weakness, artificial intelligence enthusiasm lifting international technology sectors, and large-scale government expenditure programmes boosting markets in Germany, the United Kingdom, South Korea, and Japan. For the first time in a decade, the consensus began to fracture.

The US-Iran conflict and its resolution killed the TIARA trade. The energy shock exposed a fundamental vulnerability that academic models had underweighted: energy-importing nations face structural disadvantages compared to America’s net energy exporter status. When oil prices spiked toward $120 per barrel, European and Asian markets absorbed the cost directly. The ceasefire did not just end a crisis. It reminded investors why TINA existed in the first place.

The International Energy Agency characterised the crisis as the greatest global energy security challenge in history, a designation that reflects the Strait of Hormuz’s role in transporting roughly 20% of global oil supply before the blockade.

The S&P 500’s Historic Surge Past 7,000

The S&P 500 crossed 7,000 during the week of 19 April 2026, capping a rally that gained over 10% in just 11 trading sessions. The speed caught attention across trading desks and risk committees.

According to Deutsche Bank strategist Jim Reid, a gain of 10% or more within 11 trading sessions has occurred only 15 times since 2000, excluding overlapping periods. The April rally outpaced even the rebound following President Trump’s April 2025 ‘Liberation Day’ tariff announcement, which had itself been considered unusually swift.

The milestone is both psychological and substantive. Crossing 7,000 signals investor confidence in US equity fundamentals, but the VIX at 17.48 suggests the market retains some measure of caution. This is not euphoria. It is conviction tempered by awareness that geopolitical risks persist.

The mechanics of how US equity markets absorbed and reversed the crisis-driven selloff involved coordinated central bank liquidity provisions, sector rotation into energy and defense, and sustained institutional buying during the March drawdown that created the technical foundation for April’s surge.

Institutional Exodus: Why Major Firms Are Downgrading Europe

Morgan Stanley Investment Management oversees nearly $2 trillion in assets. On 10 April 2026, Chief Investment Officer Jim Caron indicated during a virtual roundtable that the firm no longer expects European equities to outperform US stocks, reversing the consensus view MSIM had held through much of 2025. The firm is actively reducing European overweights and considering moving to an underweight position.

Franklin Templeton Institute’s Global Investment Strategist Michael Browne characterised the conflict as the fourth major external shock in six years. His team maintained a more constructive outlook on US equities from the start of 2026, anticipating that the conflict’s economic impact would disproportionately affect Europe and parts of Asia. The thesis has been validated by the data.

Capital outflows from non-US markets accelerated following the ceasefire, according to Bank of America’s weekly report citing EPFR data for the week ending 15 April 2026:

• European equity funds experienced $4.7 billion in outflows, the largest weekly withdrawal since November 2024
• South Korean funds saw record withdrawals of $2.5 billion
• Emerging market equity funds recorded net outflows for the third consecutive week

Several large investment banks upgraded US equity ratings from neutral to overweight in the days preceding 19 April, citing strong corporate earnings, particularly in the technology sector, as a buffer against residual consequences from the Middle East conflict.

The portfolio diversification implications of the TIARA reversal extend beyond simple US overweighting; investors who built international exposure during 2025 now face decisions about whether to fully exit European and Asian positions or maintain reduced allocations as long-term hedges against dollar weakness and future US policy risk.

The Earnings Divide: 14% US Growth vs 4% Eurozone

The capital flow reversal is not sentiment alone. It is backed by a stark divergence in corporate profit growth. S&P 500 companies are projected to deliver approximately 13.2% earnings growth for Q1 2026, according to LSEG and IBES data. Eurozone firms are forecast to grow earnings by roughly 4.2% over the same period.

FactSet’s blended estimate as of early April projected 13.2% year-over-year S&P 500 earnings growth, marking a sixth consecutive quarter of double-digit expansion. US growth is broad-based, spanning technology, energy, and banking sectors. European growth, by contrast, is concentrated in oil and gas, creating vulnerability to sector-specific risks.

Analysts have raised questions about whether oil-driven costs and softening business confidence will pressure Q2 guidance. Final Q1 2026 earnings results have not been reported, but the projection gap is significant enough to drive allocation decisions now.

America’s Structural Advantage: Energy Independence in Focus

The United States is a net energy exporter. Europe and Japan are importers. During the conflict, that distinction became a structural moat.

When oil prices spiked, energy-importing nations faced immediate economic pressure. Higher input costs compressed corporate margins, reduced consumer spending power, and triggered growth downgrades. The US, by contrast, benefited from record oil exports that partially offset the broader economic drag from elevated prices.

The International Monetary Fund validated this asymmetry on 14 April 2026 when it revised 2026 GDP growth forecasts. The fund cut US growth by only 0.1 percentage points to 2.3%, while eurozone growth was reduced by 0.2 percentage points to 1.1%. The relatively modest US downgrade reflected America’s greater insulation from the energy shock.

Oil prices have since stabilised at $90.12 per barrel for West Texas Intermediate, down from conflict highs near $120. Iran’s Foreign Minister Abbas Araqchi reported on 18 April that the Strait of Hormuz is “completely open” following the ceasefire. While tensions could resurface, the structural advantage persists regardless of short-term geopolitical noise.

What This Means for Global Investors

The weight of evidence points in one direction. The TINA thesis has been revived by the ceasefire sequence. Institutional capital is repositioning toward US equities based on earnings divergence, energy resilience, and the recognition that structural advantages matter during periods of geopolitical stress.

Yet risks remain. Investors should weigh the following considerations:

• The ceasefire’s extension remains uncertain, with potential expiration looming in the week following 17 April
• Charles Schwab characterised the rally as a “relief rally” without resolution of underlying geopolitical tensions
• Gold at $4,879.60 (up 1.48% on the week) suggests hedging activity continues among institutional portfolios
• The strong US dollar, with the DXY near 100, may pressure earnings for US multinationals with significant international exposure
• Q2 earnings guidance remains uncertain as analysts assess whether oil-driven costs will compress margins

Franklin Templeton’s Michael Browne described the conflict as the fourth major external shock in six years. The observation carries weight. Flexibility and vigilance remain essential as the geopolitical situation continues to evolve. The case for US equities over European stocks is strong for now, but the next shock is always closer than consensus expects.
