As 2025 draws to a close, European stocks have done more than just hold their own, they have shattered long-standing records to outperform the US by the widest margin in over a decade. In a year where global investors were told that technology was the only game in town, Europe proved that value and diversification are back in style.
The pan-European Stoxx 600 rose more than 17% this year, matching the S&P 500’s performance. However, the real story lay in the national indices. Spain’s IBEX 35 soared an incredible 48.3%, finally surpassing its pre-financial crisis peak of 2007 to hit a new all-time high. Germany’s DAX followed suit with a 22.2% gain, while the UK’s FTSE 100 climbed 20%, marking its strongest annual performance since 2013.
The AI Bubble and the Great Rotation
The year has been defined by a significant pause in the “US Tech” narrative. While giants of the Nasdaq continued to expand, their richly valued share prices began to spook investors. By mid-2025, a growing chorus of analysts warned of a mounting “AI Bubble,” citing a stark disconnect between the hundreds of billions being spent on infrastructure and the relatively slow pace of enterprise monetisation.
Concerns intensified in the final quarter of the year, with major players seeing sharp bouts of volatility as valuations reached multiples not seen since the dot-com era. This “frothiness” in Silicon Valley prompted a global “Great Rotation.” Investors increasingly pulled capital out of high-priced tech and moved it into “Old Economy” sectors like banks, energy, and industrials, where European markets offered much more attractive entry points.
The Valuation Gap: 2025 Year-End Metrics
The following table illustrates why capital fled the US for Europe, the price for a dollar of earnings in the US was nearly double that of the UK and Spain.
| Index | Price-to-Earnings (P/E) Ratio | Dividend Yield | 2025 Performance |
| Nasdaq 100 | ~33.1x | 0.8% | +21.6% |
| S&P 500 | ~29.2x | 1.3% | +17.0% |
| FTSE 100 | ~17.7x | 4.0% | +20.0% |
| IBEX 35 | ~13.5x | 4.2% | +48.3% |
Why US Protectionism Became Europe’s Catalyst
The 2025 trade environment, dominated by the re-emergence of aggressive US trade rhetoric, initially cast a long shadow over European exporters. However, what was feared as a “death knell” for European industry became a unique catalyst for growth.
While the “Liberation Day” tariffs in April roiled global markets, the subsequent negotiations led to a “Transatlantic Reset” that surprisingly favoured European industrials. The US administration’s focus on energy-independence deals forced a surge in US purchases of European defense and green energy technology as a “bargaining chip” to lower trade surpluses.
Sectors that once struggled, specifically German autos and Spanish banks, found themselves as unexpected winners. Defense contractors saw triple-digit gains as European nations fast-tracked military autonomy to hedge against US isolationism. Rather than slowing Europe down, the trade friction accelerated a “buy European” sentiment among funds looking for a hedge against US policy volatility.
A Global Shift in Leadership
On a global scale, US stocks underperformed other markets by the widest margin since 2009. The S&P 500’s 17% gain was respectable, but it was eclipsed by the MSCI ex-US index, which gained 29%. This divergence was aided by currency plays, a stronger euro and pound boosted returns for international investors, making European equities a “double win” of both price appreciation and currency gains.
As the stock market enters 2026, the events of this year have dismantled the old narrative that Wall Street is the only engine of global growth. The resilience of the DAX and the historic breakthrough of the IBEX 35 prove that when the tech hype cycles cool, the world rediscovers the value of the “Old World.”
