By mid-August 2026, global capital markets entered the closing phase of the highly anticipated US Q2 earnings season. For Southeast Asian investors tracking global capital flows, this is not just a series of financial disclosures, but a key litmus test for the 'risk resistance' and 'profit moat' of core US assets. Against a backdrop of complex macroeconomics and intensifying geopolitical struggles, the earnings resilience of US companies answers a core question: why do global capitals steadfastly buy and hold US stocks among all asset classes?
I. 2026 Q2 Earnings Panorama: Beats Become the Main Theme
Looking back, over 70% of S&P 500 companies beat Wall Street's consensus EPS estimates. While this matches the decade average, the magnitude of beats and the optimism of forward guidance are more noteworthy. After surviving 2025 H2's supply chain restructuring and inflation pressures, leading US companies achieved counter-cyclical margin expansion through cost reduction, product matrix optimization, and high-margin business expansion.
Macro-wise, the US economy showed initial 'soft landing' signs in 2026 H1. Real GDP grew moderately, and CPI moved toward the Fed's 2% long-term target. This 'steady growth, mild inflation' combo fertilized fundamental repairs for US companies. For Southeast Asian capital, a market rally driven by real earnings is far more solid than one fueled by liquidity.
II. Tech and Healthcare Dual-Engine: Concretizing the Profit Moat
1. Tech Giants: From AI Concepts to Real Cash
Tech remained the biggest highlight. If past AI hype was just 'concept expectations,' 2026 Q2 earnings turned AI into real cash contributions. Tech giants in cloud and computing infrastructure finally hit a commercialization explosion after heavy capital spending. Broad adoption of enterprise AI solutions pushed cloud revenue growth back into double digits.
Crucially, these tech giants built deep competitive moats via massive user bases and irreplaceable ecosystems. For emerging market investors in Southeast Asia, local markets have demographic dividends and growth potential, but can hardly incubate globally monopolistic tech platforms. Buying US tech leaders is essentially buying the 'tax rights' to global digitalization. This high-margin, asset-light, strong-network-effect business model is the core support of US stocks' long-term value.
2. Healthcare: Undervalued Dual Value of Defense and Innovation
Beyond tech, healthcare also performed well. With global aging and innovative drug pipelines materializing, large multinational pharma and medical device firms delivered steady results. Especially amid frequent geopolitical frictions, healthcare showed excellent 'defensive attributes.' Its earnings are less affected by economic cycles, with strong pricing power. For Southeast Asian family offices and institutional investors seeking cross-cyclical allocation, US healthcare leaders offer a perfect tool to hedge local cyclical risks.
III. Southeast Asian Capital's Perspective: Restructuring the Logic of Buying US Stocks
As a platform focused on Southeast Asian capital markets, Banggu Global Investment Research (BGUGuide) observed a significant rise in Southeast Asian funds going overseas. While local markets like SGX and Thailand's SET offer quality dividend assets like REITs, the continuous influx into US stocks reflects a deeper restructuring of asset allocation logic.
1. Currency Hedging and Hard Currency Attributes of USD Assets
Southeast Asian currencies are often vulnerable to dual shocks from US dollar cycles and commodity prices. In a complex global macro environment, allocating part of assets to USD-denominated core US stocks is a necessity for local high-net-worth individuals and enterprises to hedge exchange rate risks. US stocks represent the world's strongest economic fundamentals and the credit backing of the USD as a global reserve currency. Buying US stocks means buying the hard currency attribute of USD assets first.
2. Risk Diversification and Cross-Regional Cyclical Allocation Needs
Although Southeast Asian economies grow fast, they have structural shortcomings like relatively single industrial structures and high dependence on external capital and trade. By allocating to US stocks, Southeast Asian investors can diversify exposure to the world's most dynamic innovative economies, sharing dividends of global tech revolutions and consumption upgrades. The US market gathers the most competitive multinationals whose revenues come globally, naturally possessing cross-regional economic cycle smoothing capabilities. This 'buying a basket of top global assets' effect is unavailable in single regional markets.
3. Long-Term Growth and Mature Shareholder Return Culture
The US market has developed an extremely mature shareholder return culture over a century. This earnings season, many companies rewarded shareholders not only through earnings growth but also via massive buybacks and rising dividend ratios to directly boost EPS. Statistically, 2026 US market buybacks are expected to hit record highs. This mechanism turning corporate cash flow into shareholder returns provides a solid value floor for long-term funds. In contrast, emerging markets still lag in dividend stability and buyback execution.
IV. Market Trends and Capital Flows: Fundamentals-Driven Slow Bull Market
Market trend analysis shows this earnings season's excellence digested prior concerns over overvaluation. Though the S&P 500's forward P/E remains historically high, valuation bubbles are being solidified by strong earnings growth. Capital flows reveal a clear signal: funds are shifting from early 'betting on rate cuts' to 'chasing earnings certainty.'
Regarding sector rotation, funds show no extreme 'crowding' but formed a healthy dynamic balance between tech growth stocks and defensive value sectors like healthcare and consumer staples. This broad-based market action shows US market depth and breadth can accommodate global capitals with varying risk preferences. For Southeast Asian investors passively allocating via overseas ETFs, this healthy market ecosystem significantly reduces systemic risk exposure.
V. Conclusion: Firm Confidence, Allocating Global Core Assets
Based on 2026 Q2 earnings data and market performance, US stocks remain the 'ultimate safe haven' for global funds not through short-term policy stimulus or sentiment speculation, but rooted deeply in their unparalleled corporate 'profit moat.' Risk resistance from global expansion, profit growth driven by continuous tech innovation, and mature shareholder return mechanisms together form the core cornerstone of US stocks' long-term appreciation.
For Southeast Asian cross-border investors, answering 'why buy US stocks' is actually answering how to find certainty in global uncertainty. In the grand chess game of global asset allocation, US stocks offer not only chances to participate in top global corporate growth but also an indispensable strategic tool for asset preservation and appreciation, and hedging single-market risks. Going forward, as global capital flows deepen, relying on Banggu Global Investment Research's expertise, we will continuously unearth structural opportunities in the US market, helping investors advance steadily in volatile markets and capture true global long-term investment value.
