According to the latest data released by the U.S. Securities and Exchange Commission (SEC), net purchases of U.S. stocks by foreign investors reached $342 billion in the first half of 2026, hitting a nearly decade high. This figure represents a 28% increase year-on-year from the same period in 2025, demonstrating strong global confidence in the US stock market. Against the backdrop of intensified global economic divergence, why does capital continue to flow into US stocks? This article combines the latest market dynamics and industry analysis to interpret the underlying logic behind the accelerated allocation of foreign capital to US stocks.
1. US Economic Resilience: Global Safe Haven Effect Stands Out
In the first half of 2026, the US GDP growth rate remained stable at 3.2%, the unemployment rate stayed low at 4.1%, and core CPI fell from 4.5% at the beginning of the year to 3.8%. Despite the persistent high-interest-rate environment, consumer spending and corporate investment did not shrink significantly. The Federal Reserve maintained the federal funds rate at 5.25%-5.50% at its July meeting and hinted at the possibility of starting rate cuts before the end of the year. This "soft landing" expectation makes US assets a rare safe haven globally.
In contrast, Europe is facing stagflation risks due to the energy crisis and manufacturing weakness, the Bank of Japan's policy uncertainty has led to severe yen volatility, and emerging markets are under capital outflow pressure. The International Monetary Fund (IMF), in its latest World Economic Outlook, downgraded growth expectations for most economies except the US, further strengthening the appeal of the dollar.
2. Tech Stock Innovation Dividends: AI and Semiconductors Drive a New Round of Expansion
In the US stock market in the first half of 2026, tech stocks remained the core of capital pursuit. Companies in the AI industry chain, led by NVIDIA, Microsoft, and Google, saw their stock prices hit new highs. NVIDIA's new-generation Blackwell Ultra chip, released in July, saw order volumes exceed expectations, driving overall earnings upgrades in the semiconductor sector. The Nasdaq 100 Index rose 17% cumulatively in the first half, significantly outperforming the S&P 500's 9% gain.
Data from capital flow monitoring agency EPFR showed that net purchases by foreign investors in the tech sector accounted for 42% of total inflows across all industries. Analysts point out that the US's leading position in artificial intelligence, cloud computing, and biotechnology gives these companies global pricing power, an innovation premium difficult for other markets to replicate.
3. Policy Expectations and Attractiveness of USD Assets
Although geopolitical risks occasionally disrupt, the relative stability of the US policy environment remains a key factor for foreign investors. 2026 is a US midterm election year, but there is basic consensus between the two parties on maintaining capital market openness and the international role of the dollar. Meanwhile, the inversion of the US Treasury yield curve has ended, with the 10-year Treasury yield stabilizing around 4.2%, offering attractive risk-free returns.
Goldman Sachs strategy analysts pointed out: "Foreign investors are increasing US stock holdings not only to chase returns but also to lock in dollar liquidity. Against the backdrop of depreciation pressure on the renminbi and euro, allocating to dollar assets has become the first choice for global institutions to hedge currency risks."
4. Changes in Capital Structure: Sovereign Funds and Retail Investors Increase Holdings Together
In terms of capital sources, Asian and Middle Eastern sovereign wealth funds are the main drivers of this foreign inflow. Saudi Arabia's Public Investment Fund (PIF) increased its US stock holdings by approximately $18 billion in the second quarter, focusing on tech, new energy, and healthcare stocks. At the same time, the scale of Chinese mainland investors entering the US stock market via the Stock Connect and QDII channels also rose significantly, with net purchases reaching $20 billion in the first half, exceeding the full-year level of 2025.
Data from Interactive Brokers showed that the trading activity of global retail accounts in the US stock market increased 35% year-on-year, with younger investors especially tending to use instruments like ETFs for long-term dollar-cost averaging. This resonance between institutions and retail further solidifies the liquidity advantage of US stocks.
5. Implications for Investors: How to Seize the Dividend from Foreign Capital Inflow?
For investors interested in participating in US stocks, the continued foreign inflow provides a clear signal, but the following strategies should be noted: First, focus on sectors with concentrated capital inflows, such as semiconductors, AI software, new energy, and medical technology; second, diversify between leading blue-chip and small-to-mid-cap stocks to avoid excessive concentration; finally, be aware that after the rate-cutting cycle begins, interest-rate-sensitive sectors (such as finance and real estate) may see catch-up opportunities.
It is important to caution that current US stock valuations are at historically moderate-to-high levels, with the S&P 500 forward P/E ratio around 22 times. Should US economic data unexpectedly decline or the Fed delay policy easing, a phased correction may occur. Therefore, it is recommended that investors adopt a dollar-cost averaging or phased position-building approach and use options for risk hedging.
Conclusion
In 2026, the surge of foreign capital into US stocks hitting a decade high is essentially a collective vote by global capital for "American Exceptionalism." Supported by US economic resilience, technological leadership, and faith in dollar assets, the medium-to-long-term appeal of US stocks remains strong. However, uncertainty exists in any market. While enjoying the dividend from foreign capital, investors should remain rational and ensure diversification and risk management.
