Wall Street buckled on Tuesday. A stubborn inflation print battered equity valuations across New York, knocking the Dow Jones Industrial Average down 249 points, or 0.5%, while the tech-heavy Nasdaq Composite dropped 0.9% and the S&P 500 retreated 0.7%.
Selling accelerated the moment trading desks digested October inflation figures that defied expectations of an autumn cooldown. The US Consumer Price Index advanced 0.4% month-on-month in October, overshooting economists' consensus forecasts of a 0.3% increase. Core CPI—a metric that strips out erratic food and energy inputs—climbed 0.3% against expectations of 0.2%.
Annualised headline metrics were notably missing from the release. The Bureau of Labour Statistics omitted year-on-year calculations entirely, citing severe data collection disruptions triggered by the 2025 government shutdown during the corresponding period last year.

| Dow Jones Industrial Average | Down 249 pts (-0.5%) | -- |
| Nasdaq Composite | Down 0.9% | Intraday low: -1.3% (Nasdaq 100) |
| S&P 500 Index | Down 0.7% | 0.6% drop at 9:45 a.m. NY |
| October Headline CPI (MoM) | Above consensus | +0.4% (vs +0.3% est.) |
| October Core CPI (MoM) | Above consensus | +0.3% (vs +0.2% est.) |
| WTI Crude Oil | Softening | ~$85 per barrel |

Market Context: Persistent consumer price pressures remove the Federal Reserve's margin for error. With core inflation tracking at 0.3% on a single-month basis, monetary policy committee members are finding little justification to pause borrowing cost escalations, especially as energy markets settle around elevated baselines.
Bond and equity markets had already factored in a quarter-percentage-point hike for the central bank's final policy gathering of the year. But Federal Reserve Governor Christopher Waller upended that baseline.
Waller affirmed his explicit backing for a December policy hike—and went a step further by refusing to rule out an aggressive 50-basis-point move if inflationary pressures accelerate. Money markets moved swiftly to extend terminal rate bets past year-end, pricing out near-term relief and pressuring growth multiples.
Energy gave equities no cushion either. West Texas Intermediate crude futures hovered near $85 a barrel, down from recent peaks but still sufficiently sticky to underpin transport and production overhead across the real economy.
Semiconductor equities bore the brunt of Tuesday's risk-off liquidation. Micron Technology and Marvell Technology each shed approximately 3%, Intel surrendered 2%, and Qualcomm declined over 1%.
Nvidia stock slid more than 3%, compounding losses from Monday when the chipmaker sat out a broader market advance. The drop followed revelations concerning Chief Executive Officer Jensen Huang, who acknowledged an affair with an alleged Chinese spy over the weekend.
Yet the semiconductor retreat occurred against an otherwise massive milestone for artificial intelligence financing. AI developer Anthropic filed plans to raise up to $64.35 billion through an upcoming initial public offering, targeting a fully diluted valuation of $1.4 trillion. Strategic hardware vendors—including Nvidia, Advanced Micro Devices, and Broadcom—are actively preparing equity allocations in the offering. Even that landmark listing roadmap failed to arrest the selloff across high-multiple tech counters.
Trading desks now pivot entirely to the Federal Open Market Committee's December meeting, where Waller's rate trajectory will face its definitive test.
