These days, when looking at the U.S. stock market, really interesting signals are emerging. Expectations of interest rate cuts combined with explosive growth in the AI industry have ushered the market into a new phase. In particular, solid earnings in the semiconductor, energy, and healthcare sectors are driving stock prices, and it’s important to note that this growth is based on actual corporate profits rather than just liquidity-driven market conditions.

The S&P 500 has risen about 12% over the past year from the late 6,000s, and the Dow Jones is maintaining near all-time highs. The Federal Reserve is also open to additional rate cuts this year, which is increasingly shifting market sentiment toward risk assets. Major investment banks are also considering an additional roughly 0.25% cut within this year as their baseline scenario.

When recommending U.S. stocks, the most important factor is a company's financial health. In a volatile market, companies that can withstand fluctuations stably are ultimately the winners. Companies like Apple and Microsoft holding over $600 billion in cash and cash equivalents mean they can sustain dividends and share buybacks even during a recession.

Next, we should consider competitiveness and barriers to entry. Nvidia controls over 80% of the AI GPU market, which signifies a structural competitive advantage that extends beyond simple chip manufacturing to include the CUDA ecosystem and software tools. Such network effects make it difficult for competitors to catch up quickly.

Valuations also matter. While there is recent concern about valuation burdens across tech stocks, high P/E ratios in companies with proven long-term growth prospects do not necessarily indicate overheating. Tesla, for example, maintains a P/E ratio above 60, reflecting expectations not just for an electric vehicle company but also for new business models like robo-taxis and energy storage systems.

From a growth potential perspective, the global market’s growth axes are clearly narrowing to AI, healthcare, and clean energy sectors. Google is growing over 10% annually thanks to generative AI models like Gemini and cloud services, and Apple continues to increase software and subscription-based service revenues centered on on-device AI technology.

As of 2026, the U.S. stock market is moving within a structure where AI and semiconductors lead the entire market. Big tech firms like Nvidia, Microsoft, Amazon, and Google are building generative AI ecosystems, driving index gains. Nvidia’s revenue has increased 114% year-over-year, with data centers accounting for about 91% of total revenue. AMD is expanding its market share with the MI300 series, and Microsoft and Google are enhancing their cloud competitiveness with proprietary AI semiconductors.

The healthcare sector is polarized around obesity treatments. Eli Lilly and Novo Nordisk have reported strong results with Mounjaro and Wegovy, while traditional pharma companies like Pfizer and Merck saw stock declines of 15-20% due to slowing sales. Excluding benefits from aging populations and AI diagnostic tech, healthcare is also considered underperforming compared to the S&P 500.

The clean energy sector experienced short-term weakness due to oversupply concerns but is expected to benefit long-term from cost stabilization and falling energy storage costs. As the Fed maintains an easing stance and tax incentives under the Inflation Reduction Act remain, many analysts believe the long-term growth potential remains valid.

Consumer discretionary and service sectors are maintaining stability thanks to easing inflation and rising wages, but growth remains modest. Amazon is holding up due to AWS and e-commerce, but Prime subscriber growth has slowed, and Costco and Walmart see limited profit margin improvements despite steady sales.

In finance and fintech, despite the Fed’s rate cuts, earnings recovery is limited. JP Morgan’s net income growth is only about 5% due to narrower net interest margins, and most fintech firms are also experiencing delayed profitability improvements.

Commonly mentioned stocks among major financial institutions for U.S. stock recommendations include Nvidia, Microsoft, Apple, Alphabet, Amazon, AMD, Meta, Tesla, Costco, and UnitedHealth. Nvidia’s strength lies in being the top AI acceleration chip provider, offering a full-stack ecosystem from data centers to networks and software. Microsoft is monetizing Copilot and benefiting from Azure AI customer lock-in. Apple’s on-device AI is expected to drive high service revenue growth, and Alphabet’s Gemini 2.0 and YouTube ad recovery are key factors.

As for investment strategies, diversified investing through ETFs is the most efficient. A single purchase can expose investors to multiple industries, and recent global asset market rebounds have led ETF funds to concentrate in tech and AI sectors. The global ETF market size surpassed $17 trillion in July 2025, highlighting the importance of long-term diversification. Large asset managers like BlackRock and Vanguard are seeing rapid inflows into ETFs, with expected annual growth of 15% over the next three years.

A dollar-cost averaging strategy also works well. Regularly investing a fixed amount reduces the average purchase price and is especially suitable in volatile markets. JP Morgan Asset Management reports that over ten years of consistent investment in the S&P 500 results in less than a 5% chance of loss, and Vanguard also considers this approach effective for psychological stability and risk mitigation.

Risk management is key to all investment strategies. Limiting position sizes, setting stop-losses, and diversifying across sectors are fundamental principles. During FOMC, CPI, or earnings release weeks, reducing positions can help manage volatility. Quarterly rebalancing to adjust overheated sector weights and maintain profit-loss balance is also important.

Ultimately, the 2026 market is in the early stages of a gradual bull market. Structural growth driven by earnings and centered on AI is likely to continue, and if the Fed maintains its easing stance, risk appetite may gradually strengthen. While short-term adjustments due to tech stock overheating or geopolitical risks remain, stable inflation and solid corporate earnings underpin the market’s downside support.

The key strategy for the next five years is long-term diversification and risk management. Building a portfolio with ETFs, regularly rebalancing, and employing dollar-cost averaging can help achieve stable compound returns amid short-term volatility. When receiving U.S. stock recommendations, it’s wise to prioritize a company’s fundamentals and long-term growth prospects.
