The Nasdaq Composite (NASDAQINDEX: ^IXIC) dropped 5.3% in October, marking its worst monthly performance since early 2025 as capital expenditure anxiety surrounding artificial intelligence infrastructure rattled global equity markets.
The Bottom Line
- The Nasdaq Composite fell 5.3% in October due to surging AI infrastructure spending and mixed free cash flow reports from major technology firms.
- Despite short-term volatility, historical data shows the index has averaged a 24% return over the 12-month period following monthly drawdowns of at least 5%.
- JPMorgan Chase forecasts that capital expenditures among the five largest hyperscalers will approach $900 billion in 2026, up from over $400 billion in 2025.
Capital Expenditure Surge Pressures Big Tech Valuations
The recent market pullback was driven by investor anxiety over the sheer scale of financial outlays committed to artificial intelligence hardware and data centers. According to data tracked by JPMorgan Chase, capital expenditure spending among the five largest hyperscalers exceeded $400 billion in 2025 and is projected to approach $900 billion in 2026, marking a substantial upward revision from earlier forecasts of $736 billion. Globally, JPMorgan expects total AI capital expenditure to surpass $5.5 trillion by 2030, Yahoo Finance reported.
This massive spending cycle directly impacted quarterly financial statements for market leaders. Alphabet Inc. (NASDAQ: GOOGL) reported an Alphabet shortfall of $9.1 billion in free cash flow, while search revenue growth slowed to 12% compared to 17% previously. Alphabet also acknowledged that monetization rates within its AI search modes currently trail traditional search infrastructure. Concurrently, Amazon.com, Inc. (NASDAQ: AMZN) posted a free cash flow deficit more than five times wider than its figures from the previous year, triggering widespread investor questions regarding return on invested capital.
Cloud Revenue Momentum and Near-Term Market Volatility
Despite mounting free cash flow pressures, underlying cloud computing demand remains robust across major providers. BigGo Finance noted that Google Cloud revenue expanded 103%, Microsoft Corporation (NASDAQ: MSFT) Azure grew 48%, and Amazon Web Services climbed 39%, representing its fastest growth pace in five years. Amazon Web Services management indicated that capacity through 2028 is already heavily booked, guiding forward growth above 40% for 2027 and 2028—outpacing consensus market expectations.
However, near-term funding stress has materialized elsewhere in the technology ecosystem. OpenAI adjusted its fundraising target downward to $20 billion from $30 billion, simultaneously trimming its valuation goal to $1.25 trillion from $1.4 trillion as certain investors scaled back commitments, as reported by the Financial Times and highlighted by BigGo Finance. Furthermore, major indices faced severe daily pressure, with the Nasdaq-100 falling 2.56%, the Philadelphia Semiconductor Index dropping 6.09%, and the S&P 500 declining 1.25%, according to live tracking from Moomoo Securities’ demo trading competition data.
| Index / Asset | Recent Performance Metric | Context |
|---|---|---|
| Nasdaq Composite | -5.3% in October | Steepest monthly decline since early 2025 tariffs |
| Hyperscaler Capex (2026) | Approaching $900 Billion | Upward revision from $736 billion forecast earlier in 2025 |
| Historical 12-Month Return | +24% Average | Measured across 14 prior monthly declines of 5% or more over the last decade |
| Invesco QQQ Trust (QQQ) | +26% Average | Nasdaq-100 historical 12-month return following similar drawdowns |
Historical Precedent Pointing Toward a Market Rebound
While the October drop shook investor confidence, historical analysis of the past decade reveals a clear structural pattern following sharp corrections. Excluding October, the Nasdaq Composite has experienced a monthly decline of at least 5% on 14 separate occasions over the last ten years. YCharts data indicates that the index has historically rebounded quickly from these thresholds, delivering an average return of 24% over the subsequent 12-month period, Yahoo Finance reported.
JPMorgan market strategist Dubravko Lakos-Bujas emphasized that Wall Street has adopted an overly pessimistic outlook regarding data center monetization timelines. “The Street appears to be underwriting the AI data center monetization case: Elevated capex today should ultimately translate into higher revenue, stronger margins, and expanding cash flow,” Lakos-Bujas noted. Supporting this bullish historical view, the Invesco QQQ Trust (NASDAQ: QQQ)—an exchange-traded fund tracking the Nasdaq-100—has historically generated an average return of 26% during the 12 months following past drops of 5% or more.
