From 'Buying America' to 'Fleeing Wall Street': The Ongoing 'Defection' of Global Capital

In February 2026, American investors were pulling out of domestic equities at the fastest pace in at least 16 years, drawing global financial markets' deep attention to asset allocation patterns. According to data from the London Stock Exchange Group (LSEG) and Lipper, over the past six months, U.S. domestic investors had a net withdrawal of approximately $75 billion from U.S. equity products, with $52 billion flowing out in just the eight weeks from the beginning of 2026 to mid-February, marking the highest level for the same period since 2010. This phenomenon signifies the decline of the 'Buy the U.S.' strategy, as global capital accelerates its shift towards diversified allocations.

The primary reason American investors are exiting domestic equities is that the excess returns model long dominated by tech giants is facing challenges. Since the 2009 global financial crisis, tech stocks represented by 'FAANG' (Facebook, Apple, Amazon, Netflix, Google) have driven the S&P 500 index to cumulative gains of over 600% due to strong profit growth and market monopoly positions, becoming core assets for global investors. However, as artificial intelligence (AI) technology moves into deeper commercial phases, the market’s valuation logic for tech stocks is undergoing a fundamental shift.

The high investment and long-term return characteristics in the AI sector have intensified concerns about the sustainability of tech companies' profits. For example, giants like Nvidia and Microsoft are expected to spend $185 billion and $60 billion on capital expenditures in 2026 to maintain technological leadership, but it remains uncertain whether these investments will translate into actual returns. On the other hand, tech stock valuations are at historically high levels. As of February 2026, the forward price-to-earnings ratio of the S&P 500 reached 21.8 times, far higher than markets in Europe (15 times) and Japan (17 times), prompting capital to start moving toward undervalued regions.

In stark contrast to U.S. stocks, the performance of overseas markets has been significantly better than that of the United States. Over the past 12 months, the Tokyo Nikkei Index rose by 43%, the European STOXX 600 Index surged by 26%, the Shanghai CSI 300 Index increased by more than 20%, and the Korean Composite Stock Price Index (KOSPI) even doubled. This divergence has prompted U.S. investors to reconsider their asset allocation strategies.

Emerging markets have become the primary destination for capital inflows. Since the beginning of 2026, U.S. investors have poured approximately $26 billion into emerging market equities, with South Korea ($2.8 billion) and Brazil ($1.2 billion) being the top two destinations. The boom in the South Korean stock market has benefited from the enhanced global competitiveness of industries such as semiconductors and biotechnology, while Brazil has profited from rising commodity prices and economic reform dividends. Meanwhile, European markets have also attracted substantial capital inflows. Since mid-2025, U.S. capital inflows into Europe have accelerated significantly. After the Trump administration took office in January 2026, U.S. investors have invested nearly $7 billion in European stock products, sharply contrasting with the net outflow of $17 billion during his first presidential term (2017–2021).

For the U.S. market, capital outflows are not disastrous but rather a reflection of the market’s self-regulation. Among S&P 500 index constituents, technology stocks still account for more than 28%, and the redirection of capital helps reduce sector concentration risk and promotes healthy market development. Regarding global markets, U.S. capital inflows will provide growth momentum for emerging economies, but they may also increase volatility in certain markets.

The withdrawal of U.S. investors from Wall Street is the result of a combination of tech stock valuation restructuring, the rise of overseas markets, and changes in the policy environment. This phenomenon reminds us that global asset allocation needs to dynamically adapt to market changes and avoid over-reliance on a single market or sector. Looking ahead, as emerging industries such as artificial intelligence and green energy globalize, capital flows will increasingly focus on long-term value and risk balance, and diversified allocation may become a core strategy for navigating cycles.
