US Market Overview on August 13, 2026: Divergent Inflation Data Triggers Market Volatility
Today (August 13, 2026), the US stock market showed volatile and divergent trends. The three major indices opened significantly lower in the morning and gradually recovered, with tech stocks leading the market rebound in the afternoon. Ultimately, the Nasdaq rose by over 1%, the S&P 500 edged up slightly, while the Dow Jones Industrial Average fell modestly. Market sentiment shifted noticeably after the latest inflation data was released, with investors adjusting their expectations for the Federal Reserve's policy path. Angu Financial News will provide in-depth analysis of today's market dynamics, analyzing the underlying capital logic and investment opportunities.
Key Macroeconomic Data Analysis: Divergent Inflation Data, Market Expectations Re-evaluated
Today's US July CPI data showed a year-on-year increase of 3.2%, slightly higher than the market expectation of 3.1%, but the core CPI rose 4.1% year-on-year, below the expected 4.3%. This divergence has led to a reassessment of the Federal Reserve's policy path. Historically, this marks the third consecutive month that core CPI has been below expectations, showing that the disinflation trend continues, but the overall inflation level remains above the Fed's 2% target.
Meanwhile, US July retail sales data showed a month-on-month increase of 0.4%, better than the expected 0.2%, indicating that consumer spending remains resilient. This data, combined with the strong performance of the job market, provides further support for a "soft landing" of the US economy. However, the preliminary University of Michigan Consumer Sentiment Index fell to 68.5, the lowest in five months, reflecting growing consumer concerns about the economic outlook.
Angu Financial market analysts note, "The divergent performance of inflation data reflects the complex situation of the current US economy. On one hand, the disinflation trend is clear; on the other hand, core inflation remains stubborn, combined with declining consumer confidence, making it increasingly likely that the Fed will keep rates unchanged at its September meeting, which will have a profound impact on market liquidity."
Sector Rotation Analysis: Tech Stocks Lead, Energy Sector Under Pressure
Today's market showed clear sector rotation, with tech stocks leading the rally. Tech giants in the Nasdaq 100 generally rose, with NVIDIA (NVDA) up over 3%, Microsoft (MSFT) up 2.5%, and Apple (AAPL) up 1.8%. AI-related stocks performed particularly well, with C3.ai and Palantir both rising over 5%, reflecting continued market optimism about AI commercialization prospects.
In contrast, the energy sector performed weakly today, with Chevron (CVX) and ExxonMobil (XOM) falling 1.2% and 1.5% respectively, and WTI crude futures falling over 2% to $76.5 per barrel. This was mainly affected by China's latest economic data falling short of expectations and concerns about slowing global economic growth.
Defensive sectors showed mixed performance today, with utilities up 0.8%, healthcare up 0.3%, while financials fell 0.5%. Bank stocks were generally under pressure, with JPMorgan Chase (JPM) and Bank of America (BAC) falling 0.8% and 1.2% respectively, reflecting market concerns about changes in the interest rate environment.
Notably, the semiconductor sector performed strongly overall today, with the Philadelphia Semiconductor Index up 1.8%. Besides NVIDIA, major chip manufacturers like AMD and Intel also showed good performance. Angu Financial analysis believes, "The strength of the semiconductor sector is mainly driven by sustained strong demand for AI chips and the bottoming of the industry inventory cycle, a trend that is expected to continue in the second half of the year."
Capital Flow Tracking: Foreign Capital Returns to Tech Stocks, Domestic Capital Shifts to Defensive Assets
According to today's capital flow data, the US stock market showed a pattern of foreign capital returning to tech stocks and domestic capital shifting to defensive sectors. Tech sectors saw net inflows of over $4.5 billion today, with semiconductors and software services being the main inflow directions. Meanwhile, the energy sector saw net outflows of about $1.8 billion, and the financial sector saw net outflows of about $1.2 billion.
Looking at the options market, today's S&P 500 options trading volume increased by 15% compared to yesterday, with call options accounting for 58%, a recent high, reflecting investor optimism about short-term market trends. However, the VIX index rose 2.3 to 16.8 today, showing increased implied market volatility and cautious investor sentiment.
Northbound capital net bought US stocks by about $2.8 billion today, with tech stocks accounting for over 60%, showing foreign investors' long-term optimism about US tech stocks. Meanwhile, US domestic institutions tended to allocate to defensive assets, with utilities and healthcare sectors receiving net institutional purchases of about $1.5 billion.
Key Stock Analysis: Tech Giants' Earnings Expectations and AI Commercialization Progress
Today's strong performance in tech stocks is closely related to positive news from several companies. NVIDIA announced that its next-generation AI chip Blackwell has received large-scale orders from multiple cloud computing vendors, with expected delivery to begin in the fourth quarter of 2026, further strengthening market optimism about AI chip demand.
Microsoft, at its AI developer conference today, showcased new features for its Copilot assistant and announced partnerships with several companies, boosting market confidence in its AI commercialization prospects. Apple announced it will release iOS 18 next week, with market expectations of significant upgrades to its AI functions, providing support for Apple's stock price.
On the other hand, some stocks with poor earnings performance today faced pressure. Tesla (TSLA) fell 2.3% today, mainly due to its second-quarter automotive gross margin falling to 15.2%, below the market expectation of 16.5%. Amazon (AMZN) also fell 1.2% due to slowing growth in its cloud business.
Technical Analysis: Divergent Index Trends, Key Levels to Watch
From a technical perspective, the three major indices showed divergent trends today. The Nasdaq found support around 45,000 points and successfully broke through the 45,500 resistance level, with its short-term technical pattern strengthening. The S&P 500 found support around 4,500 points, but the 4,580 resistance level above still poses a challenge. The Dow Jones Industrial Average was pressured by the 35,000 psychological level, showing relatively weak performance.
Angu Financial technical analysts note, "The strength of the Nasdaq is mainly due to the tech stock rally, but trading volume did not increase significantly, showing limited upward momentum. In the short term, 4,580 will be a key resistance level for the S&P 500, and whether it can break through effectively will determine the medium-term market trend."
Outlook: Policy-Sensitive Period, Focus on Three Key Factors
Looking ahead, Angu Financial believes that the market is currently in a policy-sensitive period, and investors should closely monitor the following three key factors:
- Federal Reserve Policy Path: With divergent inflation data, the possibility of a Fed rate hike in September has decreased, but expectations for rate cuts this year are also facing adjustment. The market will closely monitor speeches by Fed officials and changes in economic data.
- Tech Stock Earnings Performance: Mid-to-late August will enter a period of dense earnings releases from US tech giants, with the AI commercialization progress of companies like Apple, Microsoft, and Google becoming market focal points.
- Geopolitical Risks: Developments in the Middle East situation and China-US relations will have a significant impact on market sentiment, and investors need to closely follow the progress of related events.
Investment Strategy Recommendations: Balanced Allocation, Seizing Tech and Defensive Opportunities
Based on the current market environment, Angu Financial provides the following strategy recommendations for different types of investors:
- Long-term Investors: Continue to allocate to tech leaders, especially quality companies in the AI industry chain, while appropriately increasing the proportion of defensive assets such as utilities and healthcare.
- Short-term Traders: Focus on tech stock rebound opportunities, but set stop-loss levels and closely monitor changes in trading volume to avoid blindly chasing highs.
- Conservative Investors: Consider high-dividend blue-chip stocks like Coca-Cola and Procter & Gamble to obtain stable returns while reducing portfolio volatility.
Angu Financial Investment Strategy Director states, "The current market environment is complex and volatile. Investors should maintain a cautiously optimistic attitude and avoid over-concentrating on a single sector. It is recommended to adopt a balanced allocation strategy, maintaining appropriate balance between tech sectors and defensive assets to respond to risks and opportunities in different market environments."
