US Stock Market Sector Analysis – Thursday, October 30, 2025 MIXED

The US stock market opened with a risk-on rebound after Apple (AAPL) and Amazon (AMZN) earnings rekindled optimism in futures, but intraday leadership was mixed as Meta (META) and Microsoft (MSFT) weighed on growth names. The S&P 500 and Nasdaq bounced, yet the Mag 7 (AI Spenders) group finished down -3.0% on the day as META plunged 11.3% and AMZN slid 3.2%. Sector action was bifurcated: Data Center REITs led gains (+3.3%) on an Equinix (EQIX) beat while Chip Supply Chain lagged (-2.1%) despite ongoing strength in the broader chip equipment complex. Market headlines from Equinix, Western Digital (WDC) and new product launches at Super Micro (SMCI) set the tone for tech and infrastructure names today.

AI and Technology Sector Analysis

AI spending remains the central investment theme even as the Mag 7 reprice near-term growth expectations. Alphabet (GOOG) $281.35 and NVIDIA (NVDA) $202.63 continue to hold multi-week leadership, but META's (Meta (META) $664.74) 11.3% drop highlights execution and sentiment risk inside the group. Chip Supply Chain weakness (sector -2.1%) contrasts with persistent strength in Chip Equipment (+52.0% over 50d), while Infrastructure and Enterprise Software names such as ServiceNow (ServiceNow (NOW) $186.94) are benefiting from increased cloud and data-center spend.

Sector Deep Dive

Data Center REITs are in focus after Equinix (Equinix (EQIX) $819.60) outperformed with a +4.4% move following Q3 AFFO beats and recurring revenue commentary; the sector posted a +3.3% one-day gain but remains below its 50-day average by a hair (sector vs50MA: BELOW). Over the 50-day window, investors have seen the group trade with modest volatility and EQIX's strength today signals durable demand for colocation and interconnection services even as broader tech sentiment wavers.

Chip Supply Chain names cooled today, with the sector down -2.1% on the day despite a healthy 50-day trend (sector 50d:+36.4%, ABOVE). Advanced Micro Devices (AMD) $254.84 was a top decliner, sliding -3.6% and reflecting near-term order timing concerns; longer-term the 50-day trajectory shows strong cyclical recovery that should keep suppliers in focus for AI capacity buildouts. Chip Equipment broadly remains robust (50d:+52.0%), underscoring that capital intensity for fabs and test remains a primary source of durable demand in the semiconductor ecosystem.

Healthcare showed resilience with the sector +0.4% and Eli Lilly (Eli Lilly (LLY) $840.41) rallying +3.8%, reinforcing defensive leadership in an otherwise mixed tape; Healthcare is comfortably above its 50-day trend (sector 50d:+16.7%, ABOVE). The 50-day context suggests investors are rotating into quality growth and margin-stable stories amid macro uncertainty, and LLY's move exemplifies where earnings and pipeline clarity continue to drive stock selection.

Enterprise Software outperformed modestly, rising +0.7% as ServiceNow (ServiceNow (NOW) $186.94) added +2.5% on favorable commentary about enterprise AI adoption; the sector is above its 50-day trend (sector 50d:+7.9%, ABOVE). Across the 50-day window the group shows steady appreciation, reflecting recurring revenue durability and accelerated IT modernization spend that supports both licensing and cloud-driven expansion.

Infrastructure had a constructive session with a -1.2% one-day print but an above-50-day performance pattern (sector 50d:+24.1%, ABOVE); Cisco (Cisco (CSCO) $71.86) was a notable gainer at +2.2% as network upgrade cycles tied to data-center and AI deployments remain a multi-quarter tailwind. Super Micro (Super Micro (SMCI) $50.37) was a headliner to the downside (-4.4%) despite new product news, highlighting near-term order visibility and stock-specific execution risk within a healthy 50-day context for the overall sector.
