In the first half of 2026, the US stock market maintained its bullish momentum. The ongoing AI boom, strong performance from tech stocks, and continued corporate earnings growth sustained investor confidence, pushing the S&P 500 Index near its all-time highs. However, as the market heads into the second half of the year, investors are turning their attention to inflation, interest rate policies, geopolitical tensions, and whether AI investments can continue to deliver high growth. With rising uncertainty across global capital markets, the focus has shifted to managing market risks, positioning in industries with long-term growth potential, and enhancing investment flexibility through diversified allocation.
US Bull Market Continues, but Investors Eye Second-Half Risks
(Source: TradingView)
Since the start of 2026, US equities have remained strong, with the S&P 500 Index consistently approaching record highs. Tech stocks continue to be a major driver of the market. However, after a sharp rebound in the second quarter, volatility has increased, and investors are gradually shifting their focus to macroeconomic and policy changes expected in the second half. According to Morgan Stanley’s latest research, while historical data shows July is typically one of the strongest months for US stocks, this year brings several significant risks that cannot be ignored. If these factors continue to develop, they could impact the valuations of tech stocks and the broader market.
Morgan Stanley Highlights Three Key Risks: Can US Stocks Keep Setting New Highs?
(Source: MorganStanley)
1. Escalating Middle East Tensions May Drive Oil Prices and Inflation Higher
Morgan Stanley first points to geopolitical risks in the Middle East. The market initially expected that shipping in the Strait of Hormuz would return to normal, gradually improving global oil supply and potentially lowering Brent crude prices. However, renewed US-Iran tensions and concerns over disrupted energy transport have placed upward pressure on oil prices again. If energy prices continue to climb, not only will corporate operating costs rise, but inflation could be reignited, further impacting global financial markets.
2. Will the Fed Raise Rates Again? All Eyes on Policy
Another major concern is the Federal Reserve’s future interest rate policy. The market had expected the Fed to hold rates steady through year-end, but with inflationary pressures lingering, expectations for rate hikes are rising. If the Fed adopts a more hawkish stance, a high-interest-rate environment could increase corporate financing costs and suppress the lofty price-to-earnings ratios of tech stocks. For large tech companies that have seen significant gains over the past two years, interest rate changes remain a critical factor influencing share prices.
3. Is the AI Investment Boom Cooling Off?
Over the past two years, AI has become the most prominent investment theme in global capital markets. Tech giants from NVIDIA and Microsoft to Amazon and Alphabet have poured billions of dollars into building AI data centers, fueling rapid growth in semiconductors, memory, and cloud industries. However, Morgan Stanley cautions that if second-quarter earnings reports show a slowdown in AI capital spending, the market may reassess the growth trajectory of AI-related sectors. Recently, the Magnificent Seven tech leaders experienced a correction, reflecting investors’ growing concern about whether large-scale AI investments can continue to deliver matching profit returns.
AI Remains the Market’s Main Theme, Semiconductors Stay in the Spotlight
Despite short-term market volatility, AI infrastructure remains a key global investment focus. Companies such as NVIDIA, Broadcom, AMD, Micron, and SK Hynix continue to benefit from demand for AI servers, high-bandwidth memory (HBM), data centers, and cloud computing.
Key areas to watch going forward include:
- Whether demand for AI cloud services continues to grow
- If tech giants maintain high levels of capital expenditure
- Ongoing growth in the AI chip and memory supply chain
- The impact of Fed rate policy on tech stock valuations
If AI investment maintains its rapid growth, these companies are likely to stay at the center of market attention.
Rising Global Market Volatility Calls for Greater Diversification
Beyond US stocks, markets such as Korean semiconductors, Japanese tech, Chinese AI, and new energy sectors are also attracting global capital. During periods of market turbulence, more investors are adopting cross-market allocation strategies instead of concentrating on a single market. Diversifying across countries and industries helps reduce the impact of isolated events on overall portfolios, while capturing growth opportunities in global tech sectors.

Conclusion
Morgan Stanley believes the US stock market still has long-term growth potential, but investors should closely monitor three key factors in the second half of the year: geopolitical tensions in the Middle East, Federal Reserve monetary policy, and whether AI investment continues to expand. Market volatility often brings new investment opportunities. Staying on top of macroeconomic trends and corporate fundamentals, while reducing risk through diversified market allocation, will be a crucial strategy for the second half.
