September has long been a difficult month for investors, a trend famously captured by Green Day’s song, “Wake Me Up When September Ends.” Historical data confirms this: Since 1928, the S&P 500 has, on average, posted a 1.2% loss in September, making it the worst-performing month.
This week, we'll dive into whether the "September slump" is truly a risk or just market noise, suggesting it might be wise to stay active rather than "sleep through" the month. We will also provide our long-term outlook for US equities and discuss the recent rally in China’s stock market.
AI and NVDA Remain the Main Engine of Semiconductor Growth
The Q2 semiconductor financial reports reveal a clear market split: while most companies are conservative due to tariff uncertainty, AI-centric firms are thriving. Nvidia's next quarter revenue guidance of $54 billion, a 53.9% year-over-year increase, surpassed market expectations, reflecting robust AI demand. This trend is echoed by TSMC, AMD, and Micron, which also reported strong revenue growth. The divergence is evident in TSMC's capacity utilization, with advanced nodes for AI and high-end smartphones at full capacity while more mature nodes have dropped below 70%. Furthermore, inventory levels for major AI-related companies remain notably low. The overall picture confirms that AI and Nvidia are the sole primary drivers of the current semiconductor cycle.
Fed Independence Faces Historical Challenge Amidst Rising Rate Cut Expectations
The Federal Reserve's independence faces an unprecedented challenge with a potential dismissal of Governor Lisa Cook, a move that could increase political influence over monetary policy. However, the market remains calm as economic data increasingly supports a dovish pivot. Recent labor reports show a significant slowdown in job growth, and other indicators, such as rising jobless claims and flat real consumption, suggest a broader cooling of the economy. This provides ideal conditions for a soft landing and potential rate cut without risking a recession. Chairman Powell's recent shift in stance and the move to a more flexible inflation target confirm that a September rate cut is now highly likely.
Policy Reforms and Easing Tensions Fuel China's Stock Market Rally
The recent surge in the Chinese stock market is fueled by a dual policy shift focusing on "new productive forces" and "anti-involution." High-tech manufacturing provides a resilient economic backbone, with strong growth in key sectors like integrated circuits, electric vehicles, and industrial robots. Concurrently, the "anti-involution" campaign, which promotes price increases and discourages low-cost competition, and new childcare subsidies, are seen as significant reforms. These measures address long-term issues of over-investment and insufficient consumption, demonstrating the government's commitment to structural change and restoring market confidence. Additionally, a temporary easing of US-China trade tensions has reduced short-term uncertainty, further buoying market sentiment.
AI Dominance and Reduced Uncertainty Characterize a Robust Earnings Season
The Q2 US stock earnings season was robust, with 80% of S&P 500 companies beating market expectations, driven primarily by the tech, communication services, and financial sectors. A text-mining analysis of earnings calls revealed three key trends. First, the focus on "AI" continued to grow, with mentions of servers and robotics also increasing. This highlights that AI remains the core driver of capital market sentiment. Second, mentions of "tariffs" and "recession" have decreased, reflecting a reduction in policy uncertainty. Lastly, emerging themes like "stablecoins," "nuclear energy," and "defense technology" saw the largest increases in discussion, indicating that policy proposals are shaping new investment narratives.
