On July 29, 2026, the US Commerce Department released the highly anticipated Q2 Gross Domestic Product (GDP) preliminary estimate. Data showed that US real GDP grew at an annualized rate of 3.8% in Q2, higher than the final Q1 figure of 2.9% and well above the market expectation of 3.2%. This strong economic performance, coupled with the recent dovish signals from the Federal Reserve, provides ample reason for global investors to refocus on the US stock market.

GDP Data Breakdown: Consumption and Investment as Dual Engines

According to the Bureau of Economic Analysis (BEA) report, Q2 GDP growth was mainly driven by personal consumption expenditures (PCE) and nonresidential fixed investment. PCE rose 4.2% quarter-on-quarter, contributing about 2.8 percentage points to growth, reflecting strong US consumer confidence amid a tight labor market and steady wage increases. Nonresidential fixed investment grew 3.9%, with equipment investment up 5.1% and intellectual property products investment up 4.3%, indicating that corporate spending on digital transformation and technology upgrades continues to accelerate.

Inventory changes made a negative contribution to GDP, but were offset by strong domestic demand. Net exports contributed 0.3 percentage points due to the rebound in global trade. Overall, the US economy showed unexpected resilience amid easing inflation pressure and high interest rates.

Fed Policy Shift Expectations: Rate Cut Window May Open in September

Before the GDP release, the Fed concluded its two-day monetary policy meeting on July 27, keeping the federal funds rate unchanged at 5.00%-5.25%. This was the second consecutive pause after a 25-bps rate cut in March, but the post-meeting statement wording saw subtle changes: the Fed for the first time adjusted the phrase "inflation remains elevated" to "inflation has made substantial progress" and emphasized "flexible adjustments based on economic data" going forward. Markets quickly seized on this dovish signal, with the CME FedWatch tool showing the probability of a 25-bps rate cut in September jumping from 45% before the data to 68%, reigniting expectations of two rate cuts within the year.

When a rate cut cycle begins, it usually means lower risk-free rates, making stock valuations more attractive. Historical experience shows that within six months after the first Fed rate cut, the S&P 500 index has risen an average of 12.5%, with the tech sector performing particularly well. The current GDP data provides strong evidence for a "soft landing" of the US economy, reducing recession concerns while creating room for further policy easing.

US Stock Market Reaction: Tech Giants Lead, Indexes Hit New Highs

On the day of the GDP release, all three major US stock indexes closed higher. The Dow Jones Industrial Average rose 0.6% to 41,520 points; the S&P 500 rose 0.8% to 6,180 points, just a step away from the all-time high of 6,250 points set in mid-July; the Nasdaq Composite rose the most, up 1.2% to 20,350 points. By sector, technology led the gains, with NVIDIA up 2.5%, Apple up 1.8%, and Microsoft up 1.3%. The semiconductor sector as a whole rose 2.3%, as markets expect rate cuts to lower financing costs, benefiting high-growth tech companies.

Notably, the latest fund flow report from Bank of America showed that in the week ending July 28, US stock funds saw net inflows of $18 billion, a near six-month high, with the tech sector receiving about $7 billion in net purchases. This reflects growing institutional investor confidence in the US stock fundamentals and policy environment.

Core Advantages of US Stock Investment: Why Are Global Funds Flowing In?

Among major global economies, the US, with its well-developed capital markets, strong corporate innovation, and flexible policy space, remains the core choice for international capital allocation. In summary, the main reasons to buy US stocks currently include:

  • Earnings Growth Resilience: Two-thirds of S&P 500 components have reported Q2 earnings, with a beat rate of 78%, and average EPS growth of 9.2% year-over-year, far exceeding Europe and Asia Pacific. Tech, healthcare, and industrials showed particularly strong earnings growth.
  • Global Leader Concentration: The US hosts eight of the world's ten largest listed companies by market cap, covering AI, cloud computing, new energy, biotech, and other frontier fields. These companies dominate global value chains and benefit more fully from technological progress and global demand recovery.
  • Abundant Liquidity and Buyback Support: Although the Fed is still shrinking its balance sheet, large-scale share buyback programs by US companies provide steady buying support. In Q2 2026, S&P 500 companies repurchased a total of $318 billion in shares, up 11% year-over-year, with full-year buybacks expected to exceed $1.2 trillion.
  • Currency and Safe-Haven Appeal: Amid frequent global geopolitical conflicts (e.g., US-Iran tensions), the US dollar continues to play a safe-haven role. The dollar index fluctuated in the 101-103 range in Q2, providing additional currency gains for overseas investors.

Risk Warning: Watch for Inflation Stickiness and Elevated Valuations

Despite the optimistic outlook, investors should be aware of potential risks. First, the core PCE price index annualized quarterly rate in the Q2 GDP report was 2.7%, down from 3.0% in Q1 but still above the Fed's 2% target. If inflation proves stickier than expected, rate cuts could be delayed. Second, the S&P 500 currently trades at a P/E ratio of about 23x, historically elevated, and the tech sector at 31x, with some individual stocks already pricing in future growth. Finally, the November US midterm elections are approaching, and policy uncertainty could trigger market volatility.

For new investors, it is recommended to use index ETFs (e.g., S&P 500 ETF) or sector ETFs (e.g., tech ETF) for diversification, and use dollar-cost averaging to smooth out costs. Also, pay attention to economic data before the Fed's September meeting, especially August nonfarm payrolls and CPI reports, which will be key variables validating the economic trend.

Conclusion: Seize the Dual Favorable Window

Overall, the US Q2 GDP growth beat combined with the Fed shift expectation provides a rare "strong economy + loose policy" combination for US stocks. For investors seeking global asset allocation, now is a good opportunity to review and increase US stock positions. Short-term volatility may occur due to technical adjustments, but medium-to-long-term earnings growth and falling interest rates will be the core drivers of stock price gains. In the second half of 2026, US stocks are likely to continue hitting new highs amid challenges.
