Market Overview: Major Indices Volatility Narrows, Sector Divergence Intensifies
On August 23, 2026, after several days of volatility, the US stock market showed a volatile pattern with diverging trends across the three major indices. By the close, the Dow Jones Industrial Average fell slightly by 0.12%, the S&P 500 index rose modestly by 0.23%, while the Nasdaq Composite Index rose by 0.45%, showing relatively strong performance. Trading volume decreased slightly from the previous day, reflecting investors' cautious sentiment ahead of the Jackson Hole meeting.
In terms of sector performance, tech stocks and defensive sectors became the main highlights, while energy and financial sectors performed relatively weak. This "barbell" market structure reflects investors' defensive mindset in an uncertain environment, while maintaining optimistic expectations for the tech sector, especially AI-related areas.
Tech Stock Rally: AI Hardware Sector Leads Market Direction
Tech stocks performed prominently in today's trading, particularly in AI hardware-related sectors. NVIDIA (NVDA) stock rose 2.8%, with market capitalization returning above $2.5 trillion, becoming the main driver of the Nasdaq index. The company's next-generation AI chip released recently received positive market evaluations, with several investment banks raising their target prices. AMD also showed strong performance, rising 3.2%, as market expectations for its AI chip market share continued to increase.
The strong performance of the AI hardware sector was mainly driven by several factors: first, major global tech giants continue to increase investment in AI infrastructure, creating strong demand for high-performance chips; second, the latest industry report shows that AI computing demand growth exceeded expectations, with the global AI chip market expected to reach $500 billion in 2026; third, many Wall Street analysts are optimistic about the long-term growth potential of the AI hardware industry chain, believing that related companies will benefit from the acceleration of AI technology commercialization.
The software and cloud computing sectors also performed well, with Microsoft (MSFT) rising 1.5% and Amazon (AMZN) rising 1.8%. The market's understanding of the importance of cloud computing services in the AI era continues to deepen, especially cloud computing companies that can provide AI infrastructure and development platforms are favored by investors.
Defensive Sectors Strengthen: Defensive Choices Amid Uncertainty
While tech stocks rebounded, defensive sectors continued to attract capital, showing investors' cautious attitude towards the current market environment. The consumer staples sector rose 0.8%, the healthcare sector rose 0.7%, and the utilities sector rose 0.5%.
The strong performance of defensive sectors is mainly based on the following reasons: first, there are differences in market expectations for the Federal Reserve's policy path, and economic data performance is inconsistent, making investors tend to allocate defensive assets; second, geopolitical tensions continue, increasing demand for safe-haven assets; third, some defensive sector companies recently released better-than-expected earnings, providing support for their stock prices.
Of particular note, high-dividend defensive sectors performed exceptionally well today, with an average increase of 0.9%. In the current low-interest-rate environment, stable and relatively high dividend yields have strong appeal to investors, especially against the backdrop of increasing market volatility.
Market Capital Flows: ETF Funds Continue to Flow into Tech Sectors
In terms of capital flows, ETF funds continue to show a "barbell" allocation characteristic. According to the latest data, tech ETFs had net inflows of about $1.5 billion today, with AI-related ETFs having net inflows of over $800 million, reaching a recent high. At the same time, defensive ETFs also obtained net inflows of about $1 billion, reflecting investors' balanced strategy between offense and defense.
Notably, capital flows show obvious structural characteristics: large-cap tech stocks continue to receive capital favor, while small and medium-sized tech stocks face capital outflows. This indicates that investors are also screening within the tech sector, paying more attention to leading companies with core competitiveness and profitability.
In terms of regional capital flows, Asian capital (including Hong Kong and Taiwan) continued to net buy US stocks today, especially tech stocks and AI-related stocks. This reflects cross-border investors' recognition of the long-term value of US tech sectors and their preference for US tech giants in global asset allocation.
Market Focus: Policy Game Before Jackson Hole Meeting
The current market's main focus is on the Jackson Hole Global Central Bank Symposium to be held on August 25-27. Investors expect Fed Chair Powell to release signals about future monetary policy direction at this meeting, especially hints about the possibility of a September rate cut.
Currently, market expectations for a September Fed rate cut have risen to 70%, but policymakers still have different views on inflation trends and economic growth prospects. The latest released July PCE price index rose 2.8% year-on-year, higher than the Fed's 2% target, but the month-on-month increase has slowed. This data performance makes the Fed face the dual challenge of balancing inflation and economic growth in the rate cut issue.
Market analysts generally believe that the policy signals at the Jackson Hole meeting will have an important impact on recent market trends. If Powell releases dovish signals, it may further push the stock market higher; conversely, if he emphasizes inflation risks, it may trigger a market correction.
Industry Observation: Value Reassessment of AI and Cloud Computing Sectors
From an industry perspective, the AI and cloud computing sectors are undergoing a value reassessment process. As the commercialization process of AI technology accelerates, market expectations for related companies' profitability continue to be raised. According to the latest industry analysis report, the average expected P/E ratio of AI-related companies has risen from 25 times at the beginning of the year to the current 32 times, but it is still below the historical peak.
The cloud computing sector is also benefiting from AI development, and cloud computing companies that can provide AI infrastructure and development platforms are favored by the market. It is expected that by 2027, the market size of AI-driven cloud computing services will reach $800 billion, with a compound annual growth rate exceeding 40%.
At the same time, traditional tech companies are also accelerating their transformation to AI, with tech giants such as Microsoft and Google successively launching their own AI products and solutions. This trend will further promote the value reassessment of the AI and cloud computing sectors.
Technical Analysis: Key Support and Resistance Levels
From a technical perspective, the S&P 500 index is currently running near the key support level of 4500 points, which is also where the 50-day moving average is located. If the index can effectively stand firm at this level, it may indicate the end of the short-term adjustment and the resumption of an upward trend; conversely, if it falls below 4500 points, it may further test the support near 4400 points.
The technical trend of the Nasdaq index is relatively optimistic, currently located above the key upward trend line with good trading volume. In the short term, the index may challenge the resistance level near 15000 points, and whether it can effectively break through will determine the medium-term trend.
From a sector rotation perspective, the market has shown obvious "tech-defensive" rotation characteristics recently. When market risk appetite improves, tech stocks lead the gains; when market uncertainty increases, defensive sectors strengthen. This rotation pattern may continue to exist for some time in the future.
Investment Strategy: Barbell Allocation to Deal with Market Volatility
In the face of the current complex market environment, a barbell investment strategy may be a good choice. That is, to allocate high-growth tech leaders and stable defensive assets at the same time to balance risk and return.
In the tech sector, it is recommended to focus on AI hardware and software companies with core competitiveness, especially those that have achieved commercialization and generate stable income. At the same time, cloud infrastructure providers are also worth attention, as they will directly benefit from the computing power demand growth brought by AI development.
In the defensive sector, high-dividend consumer staples and healthcare companies are worth attention, as they can not only provide stable dividend income but also have strong risk resistance. The utilities sector is also an important part of defensive allocation, especially against the background of a stable interest rate environment.
For long-term investors, the current market volatility may be a good opportunity to position quality assets. It is recommended to adopt a strategy of buying on dips, gradually allocating those high-quality companies with long-term growth potential, rather than chasing short-term market hotspots.
Market Outlook: Dual Game of Policy Signals and Earnings Expectations
Looking ahead to the next week, the market will face the dual game of policy signals and earnings expectations. The policy statements at the Jackson Hole meeting, as well as the upcoming August PMI data and initial jobless claims data, will become key factors affecting market trends.
In the long run, the US stock market still has good investment value. On the one hand, after experiencing a high-interest-rate environment, the US economy is expected to achieve a soft landing; on the other hand, technological innovation, especially the rapid development of AI technology, will provide new impetus for economic growth. For Hong Kong and Taiwan investors, allocating US core assets through ETFs is still an important way to achieve global asset allocation.
Overall, the US stock market on August 23, 2026 showed a divergent pattern, with tech stocks and defensive sectors simultaneously receiving capital favor, reflecting investors' balanced strategy in an uncertain environment. As the Jackson Hole meeting approaches, the market will continue to focus on policy signals and look for market opportunities in the next stage.
