In July 2026, the US stock market staged a strong rebound after first-half volatility. As of July 28, the S&P 500 had risen over 5% month-to-date, and the Nasdaq hit a record high, recovering all losses from Q2 due to tariff concerns. Behind this summer rally is the confluence of expectations for a Fed policy shift, accelerated commercialization of AI, and global capital reallocating to US stocks, providing a fresh footnote to the long-standing question of "Why buy US stocks."
1. Liquidity Feast Restarted: Rate Cut Expectations Fuel Valuation Expansion
On July 26, the Fed kept the federal funds rate at 4.50%-4.75% but adopted a noticeably dovish tone. Chairman Walsh stated at the press conference that the path of inflation decline has formed, and if data continues current trends, the door to a fall rate cut will open. This statement ignited market sentiment, with the 10-year Treasury yield falling from 4.2% to 3.95%, and rate-sensitive sectors like real estate and utilities rising first. Morgan Stanley strategist Mike Wilson noted: "Rate cut expectations not only lower corporate financing costs but also increase the discounted value of future cash flows—this is the underlying logic behind the valuation premium of US stocks."
1.1 Global Capital Returns to Dollar Assets
Historical patterns show that when the Fed ends its rate hike cycle, global capital accelerates into US stocks. According to EPFR Global data, $21 billion flowed into US equity funds in the third week of July, the highest weekly inflow since 2025, with most coming from long-term allocation funds in Europe and Asia-Pacific. Behind this capital migration is the relative resilience of the US economy among developed economies—Q2 2026 GDP annualized growth hit 2.8%, far exceeding the eurozone's 0.3% and Japan's 1.1%. The simple logic "Buy US stocks to buy the growth momentum of the world's strongest economy" is once again confirmed.
2. AI from Concept to Monetization: Tech Giants Redefine Growth Boundaries
The core driver of this US stock rally comes from the AI field. On July 15, Google parent Alphabet announced that its new AI model "Gemini 3" outperformed GPT-5 on multimodal tasks and launched an enterprise AI agent platform, driving a revaluation of the entire tech sector. Subsequently, Microsoft, Amazon, and Nvidia reported better-than-expected earnings, with cloud AI-related revenue up 112% year-over-year, becoming the biggest highlight. Goldman Sachs tech analyst James Cordwell said: "We are witnessing the transformation of AI from a cost center to a profit center. US tech giants have the world's best AI infrastructure and richest application scenarios, an advantage hard to replicate in other markets."
2.1 Nvidia's "Compute Arms Dealer" Status
On July 22, Nvidia's stock broke $200, reaching a market cap of $4.5 trillion. Its Q1 FY2027 data center revenue grew 180% year-over-year, with gross margin at 78%. Bernstein Research noted that over 70% of global AI computing power comes from Nvidia chips, making it the biggest "pick-and-shovel seller" in the AI gold rush. For investors, positioning in Nvidia is equivalent to owning the beta return of the AI revolution—a unique investment dividend from the US stock ecosystem, hard to find in China, Europe, or elsewhere with such globally dominant technology assets.
3. Market Depth and Institutional Dividends: The Irreplaceable Soft Power of US Stocks
Beyond macro and industry factors, the institutional advantages of US stocks are also evident in this rally. First, market maker systems and programmatic trading provide extremely high liquidity, with S&P 500 components averaging a daily turnover of about 1.2%, far exceeding emerging markets. On July 24, the Dow Jones quickly recovered after a 2.3% intraday swing—a resilience hard to match elsewhere. Second, the SEC's stringent disclosure and insider trading rules protect small investors, reducing the risk of pitfalls. Moreover, the rich derivatives market—such as VIX futures and leveraged ETFs—offers diverse hedging tools, making investment strategies more flexible.
4. Diversify Risk: Anchoring Certainty Amid Uncertainty
Geopolitical risks are flaring up, and global trade patterns are reshaping. Against this backdrop, allocating assets to US stocks adds a layer of "institutional insurance" to portfolios. The US capital market's rule of law, the dollar's reserve currency status, and corporate innovation capabilities make it a safe haven for global capital in turbulent times. For instance, in the first half of 2026, while the MSCI Emerging Markets Index fell 8%, the S&P 500 only corrected 2% and quickly recovered in July, highlighting its relative hedging properties versus other markets.
5. Risk Warnings and Investment Strategies
Despite the US stock market's long-term advantages, short-term volatility is unavoidable. Current pricing already factors in three rate cuts this year; if inflation data reverses or AI commercialization disappoints, a 10%-15% correction is possible. We recommend a dollar-cost averaging strategy, prioritizing S&P 500 index ETFs (e.g., SPY) or Nasdaq 100 index ETFs (e.g., QQQ), supplemented by a few high-conviction tech leaders. For individuals wanting to share in AI dividends, watch for the upcoming "Specialized and Sophisticated" US stock ETF launching in August—it selects 50 companies with moats in core algorithms, chip design, and data infrastructure.
Conclusion
The summer 2026 US stock rally is no coincidence; it reflects the Fed's liquidity support, substantive AI breakthroughs, and global capital's structural demand for dollar assets. For Chinese investors, with proper FX management and risk control, allocating to US stocks through compliant channels remains one of the most effective ways to achieve internationalization, diversification, and long-term asset appreciation. Buying US stocks means buying not just shares but a mature market system, an innovation-driven economy, and the right to participate in the global tech wave.
