The notion of US exceptionalism has been deeply ingrained in investment thinking, but recent experience underscores the need for a broader perspective. Global markets are dynamic, and leadership is not static. By recognising these shifts and positioning portfolios accordingly, investors can build resilience and unlock growth in a world where opportunity is increasingly dispersed.
For decades U.S. equities have been viewed as the cornerstone of global investing – underpinned by innovation, liquidity, and resilience. The narrative of “US exceptionalism” has shaped asset allocation decisions for generations, with investors often defaulting to American markets as the primary driver of growth. Yet, 2025 has challenged this long-standing assumption. Recent performance trends reveal that no single market holds a permanent advantage, and understanding this shift is critical for building resilient portfolios in an era of structural change.
Historically, the US has enjoyed a unique position in global markets, thanks to its technological leadership, deep capital markets, and strong corporate governance. However, the past year has demonstrated that other markets offer attractive opportunities. Emerging markets – from Brazil to China – have delivered robust returns, while the Korea KOSPI Index surged by more than 65% to the end of November 2025, a remarkable performance that few anticipated. Even the UK, despite lacking the large IT and AI proxies that dominate US indices, has so far outperformed American equities in 2025.
Crucially, AI is no longer just a US story. China and other countries are investing heavily in AI research, commercial applications and specialised hardware. Chinese companies and research groups are developing advanced models such as DeepSeek and AI chips, while South Korea, Taiwan and Europe are major players in semiconductor manufacturing and packaging – all essential parts of the AI value chain.
These shifts are not merely cyclical, it reflects deeper structural changes in global growth dynamics. As economic power disperses across regions, investors who remain overly concentrated in US assets, risk missing out on compelling opportunities elsewhere.
Opportunities beyond the U.S.
Diversification has traditionally been viewed as a defensive measure – a way to mitigate volatility and protect against downside risk. Today, it is increasingly a proactive strategy for capturing growth. By broadening exposure beyond the US, portfolios can tap into long-term trends that we believe will support returns in the years ahead.
Asia stands out as a region with long‑term growth drivers. The United Nations projects Asia will hold around 60% of the world’s working‑age population (ages 15–64) in 20301, supporting a sizeable labour pool and rising domestic demand. Even by 2050, its estimated Asia will still account for over half of the global working‑age population. Together with rising middle‑class consumption and technological innovation, these structural factors are driving growth across markets such as India, Korea and China. Similarly, other emerging markets offer attractive valuations and higher growth potential compared to developed economies. These dynamics helped drive strong performance in 2025 and are likely to underpin further gains as global economic leadership gradually shifts east (see Figure 1).
