The Nasdaq Composite Index experienced its most significant decline in eight months during November, pressured by heavy selling in major artificial intelligence (AI) stocks and falling behind the S&P 500 Index for the first time in three months, raising concerns about the sustainability of the AI-driven market rally.
The AI Sell-off Continues
The Nasdaq has fallen 4.3 percent so far this month, compared with a nearly 2 percent drop in the S&P 500, marking its steepest retreat since March. Much of the slide has been driven by weakness in sector heavyweights. Nvidia (NVDA) shares fell over 8% in November, despite reporting record quarterly revenue of $39.3 billion, a 78% increase from the previous year. Apple (AAPL) experienced a 1% decline. Meta Platforms (META) shares decreased by 7%. Tesla (TSLA) declined by 11%. Amazon (AMZN) lost about 4%.

These declines occurred even as these companies delivered solid third-quarter earnings, highlighting growing unease about the durability of the AI trade. Concerns about an AI-driven bubble have intensified as prominent investors cut exposure to Nvidia, the flagship of the rally. SoftBank’s Masayoshi Son exited his position in Nvidia, selling his entire $5.83 billion stake to fund other AI investments. Michael Burry held significant short positions in companies like Nvidia and Palantir, indicating skepticism about current valuations. These moves underscore apprehensions about a potential AI-driven market bubble.
The market’s volatility is further influenced by upcoming corporate earnings reports and economic data releases. Nvidia’s earnings report, scheduled for November 19, 2025, is highly anticipated due to Nvidia’s significant role in the AI sector. Home Depot and Walmart are set to release quarterly results, providing insights into consumer spending trends. Delayed reports on employment and inflation, postponed due to the recent government shutdown, are expected to shed light on economic activity and potential rate cuts. Additionally, the Federal Reserve will release minutes from its October meeting, offering more insight into the unusual split among policymakers following a quarter-point rate cut.
The strength of the AI narrative has pushed S&P 500 valuations to elevated levels, placing the index among the world’s most expensive markets and nearly two standard deviations above its long-term average. This has led to increased scrutiny and caution among markets regarding the sustainability of current market valuations.
The Nasdaq’s recent underperformance underscores the market’s sensitivity to AI stock valuations and broader economic uncertainties, setting the stage for continued volatility as investors await key earnings reports and economic data.
