Wall Street Institutions' View: Why Buying US Stocks Remains the Core Logic for Global Capital Allocation in the Second Half of 2026
In August 2026, against the backdrop of multiple challenges in global financial markets, the latest strategy reports released by major Wall Street investment banks and research institutions show that despite increased global economic uncertainty, the US stock market remains the core choice for global capital allocation. Top institutions unanimously agree that the US stock market still has irreplaceable advantages in terms of liquidity, innovation capability, and profit growth, especially during this critical period of global economic restructuring.
The Unique Position of US Stocks in Global Asset Allocation
According to Morgan Stanley's latest "Global Asset Allocation Strategy Report for the Second Half of 2026," the allocation ratio of US stocks in global investment portfolios should be maintained at 40%-45%, a slight increase from the same period in 2025. The report points out that the US stock market has three core advantages: first, the depth and breadth of the US stock market lead globally, providing investors with abundant choices; second, the innovation capability and technological leadership of US companies continue to strengthen globally, especially in cutting-edge fields such as artificial intelligence, biotechnology, and clean energy; finally, the status of the US dollar as a global reserve currency gives US stocks a natural hedge attribute in global asset allocation.
The Global Head of Strategy at Goldman Sachs stated in a recent investor conference call: "Despite facing geopolitical risks and inflationary pressures, the US stock market remains the 'cornerstone' of global capital allocation. Our quantitative models show that the correlation between US stocks and other major markets has decreased over the past five years, providing global investors with better diversification opportunities."
Sector Analysis: Technology and Healthcare Leading Growth
Latest research reports from major Wall Street investment banks show that technology and healthcare sectors will continue to lead the US stock market in the second half of 2026. The analyst team at J.P. Morgan pointed out in their "Investment Strategy for Technology Stocks in the Second Half of 2026" that the commercialization process of artificial intelligence technology is accelerating, expected to bring more than 30% revenue growth for related companies. Especially in data centers, cloud computing, and enterprise-level applications, leading companies have already established clear competitive advantages.
Meanwhile, the healthcare sector is also favored by multiple institutions. The Global Head of Healthcare Research at UBS Group stated: "Driven by both population aging and medical technology innovation, the healthcare sector will become one of the most defensive and growth-oriented sectors in the US stock market. We see many disruptive innovation companies in biotechnology, digital healthcare, and medical devices."
Notably, Wall Street institutions' views on the energy sector have also changed significantly. With the acceleration of global energy transition, traditional energy companies are actively developing renewable energy fields. Citigroup's energy analysts pointed out in their latest report: "The energy sector is undergoing structural change, and successfully transformed traditional energy giants and emerging renewable energy companies will have opportunities for revaluation in the US stock market."
Comparison Between US Stocks and Other Markets: Advantages Still Obvious
Compared with mature markets such as Europe and Japan, the US stock market still maintains clear advantages in multiple dimensions. According to BlackRock's latest "Global Market Comparison Study," the US stock market leads globally in the following aspects: first, the profit growth rate of the US stock market is expected to reach 8%-10%, significantly higher than 4%-5% in Europe and 2%-3% in Japan; second, although the valuation of the US stock market is at a historically high level, it still has relative attractiveness considering its profit growth prospects; finally, the liquidity and trading convenience of the US stock market are second to none globally, providing investors with a better trading experience.
Compared with emerging markets, although the growth potential of the US stock market may not match some high-growth emerging markets, it has clear advantages in risk control and stability. BlackRock's comparison study between emerging and developed markets shows: "Against the backdrop of increasing global economic uncertainty, the US stock market provides better risk-adjusted returns, especially in an environment of rising geopolitical risks."
Investment Strategies in the Current Market Environment
Facing the complex market environment in the second half of 2026, Wall Street institutions generally recommend a "core-satellite" investment strategy. The Bank of America Global Research team suggested in their latest report: "Investors can allocate 70% of their funds to US core index ETFs to obtain market average returns; at the same time, allocate 30% to high-growth potential industry ETFs and selected individual stocks to enhance the aggressiveness of the portfolio."
At the operational level, Goldman Sachs proposed a "barbell" allocation strategy, simultaneously allocating high-growth technology stocks and defensive stocks with stable cash flows to balance the risk and return of the portfolio. Morgan Stanley suggests that investors focus on companies with strong pricing power and global competitiveness, which can maintain profit growth in an inflationary environment.
Notably, Wall Street institutions generally believe that the volatility of the US stock market may increase in the second half of 2026, but this does not change the long-term positive fundamentals. The Chief Global Market Strategist at J.P. Morgan stated: "Short-term volatility is the norm of the market, but the long-term growth logic of the US stock market has not changed. Investors should focus on the fundamentals and long-term value of companies, rather than being disturbed by short-term market fluctuations."
Risk Warnings and Response Strategies
Although Wall Street institutions are generally optimistic about the prospects of the US stock market, they also remind investors to pay attention to potential risks. According to Morgan Stanley's analysis, the main risks facing the US stock market include: first, changes in the Federal Reserve's monetary policy may put pressure on market valuations; second, escalation of geopolitical tensions may bring uncertainty; finally, corporate profit growth may be affected by rising costs and slowing demand.
In response to these risks, Wall Street institutions have proposed corresponding strategies. UBS Group suggests investors: "Maintain appropriate cash reserves to cope with market fluctuations; at the same time, increase allocations to defensive sectors such as consumer staples and utilities to reduce the overall risk of the portfolio." Citigroup suggests that investors focus on companies with strong pricing power and global layout, which can better cope with inflation and geopolitical risks.
Conclusion: The Core Logic of Why to Buy US Stocks
Combining the latest views from major Wall Street institutions, we can see that the core logic of why to buy US stocks mainly includes the following aspects: first, the US stock market has the world's highest-quality listed companies, which are in a leading position in terms of innovation, profitability, and global competitiveness; second, the US stock market provides abundant investment tools and products to meet the needs of different investors; again, the status of the US dollar as a global reserve currency gives US stocks a natural hedge attribute in global asset allocation; finally, the depth and breadth of the US stock market provide investors with better diversification opportunities.
Despite facing short-term fluctuations and risks, Wall Street institutions generally believe that the US stock market will remain the core choice for global capital allocation in the second half of 2026 and beyond. For investors, understanding the core advantages of the US stock market, formulating reasonable investment strategies, and maintaining a long-term investment perspective are the keys to achieving wealth appreciation.
As the Chief Global Strategist at Morgan Stanley said: "During this critical period of global economic restructuring, the US stock market not only provides growth opportunities, but more importantly, it offers global investors a relatively stable investment environment. This is the core logic why the reasons for buying US stocks still hold true in 2026."
