US Stock Market Sector Analysis – Friday, August 01, 2025 BEARISH

Markets reacted sharply to a string of macro headlines and earnings takeaways, with tariffs and economic jitters cited as the day’s dominant driver. The Mag 7 roster weighed on the session, with Amazon (AMZN) plunging 8.3% to $214.75 and NVIDIA (NVDA) down 2.3% to $173.49, contributing to a broad pullback that left 19 sectors lower and only 5 higher. Chip Supply Chain and Infrastructure led early weakness, declines of -2.6% and -3.3% respectively, while Healthcare saw selective strength as Eli Lilly (LLY) rose 3.0% to $756.98 amid defensive flows. The US stock market and S&P 500 closed with clear risk-off tone after the headlines and Big Tech earnings takeaways pressured momentum names.

AI and Technology Sector Analysis

AI and technology themes showed durability within a choppy tape: NVIDIA (NVDA) at $173.49 remains a leader with a 50-day gain of 31.8% even as the Mag 7 group fell 3.0% on the day. The Chip Supply Chain held above its 50-day average (+17.6%), but Marvell (MRVL) slipped 7.4% to $74.29, underscoring idiosyncratic volatility across suppliers. Infrastructure (50d:+21.5%) and enterprise deployments continue to support demand for data-center and networking gear even as Enterprise Software (50d:-2.2%) and IT Services (50d:-11.7%) trade lower, signaling a divergence between hardware-driven AI buildout and softer software/services spending near-term.

Sector Deep Dive

Chip Supply Chain exhibited clear bifurcation today: the group is +17.6% vs its 50-day average but traded down -2.6% on the day and -5.6% over five days, reflecting profit-taking after a run-up. Marvell (MRVL) fell 7.4% to $74.29 and is a reminder of name-specific risk even in a strong 50-day trend; Lam Research (LRCX) bucked the intra-group weakness, rising 1.6% to $95.84, showing chip equipment demand remains intact. Over the 50-day window the sector’s positive trend supports continued exposure to select suppliers tied to AI capacity expansion.

Infrastructure was the weakest sector today with a 1-day decline of -3.3% despite sitting +21.5% above its 50-day average, highlighting a short-term pullback inside a durable uptrend. Hewlett Packard Enterprise (HPE) led losses in the group, down 4.3% to $19.41, signaling investor sensitivity to near-term spending cues. For portfolio positioning, the infrastructure 50-day strength suggests selectively trimming rallies while maintaining exposure to names benefiting from data-center modernization.

Healthcare softened with the sector down -0.9% on the day and lagging badly over 20 and 50 days (20d:-11.5%, 50d:-7.9%); UnitedHealth Group (UNH) dropped 4.7% to $231.57 following company-specific corporate changes, amplifying the sector’s volatility. Eli Lilly (LLY) provided a defensive counterpoint, rising 3.0% to $756.98 and reinforcing concentration risk within healthcare where a handful of leaders can influence the group. Given the active HIGH alert on Healthcare’s 20-day decline, risk managers should favor larger-cap defensives and avoid weak small-cap biotech exposure despite short-term relief rallies.

Enterprise Software and IT Services are under pressure: Enterprise Software is -2.8% today and sits -2.2% vs its 50-day, while IT Services is down -2.8% and a notable -11.7% vs its 50-day average. Accenture (ACN) slumped 4.4% to $250.21, underscoring demand concerns and driving the sector-level softness. The 50-day context argues for cautious exposure; investors should prioritize cash-flow resilient vendors and defer aggressive entries until five-day and 20-day momentum stabilizes.

Logistics and Cybersecurity remain structural areas of concern with active HIGH alerts: Logistics is down -2.4% today and -11.9% over 20 days with an average of five consecutive down days and sits -5.5% vs its 50-day, while Cybersecurity is -1.3% today and -12.3% over 20 days, trading below its 50-day trend (+3.6% over 50d not withstanding). These 50-day readings indicate loss of intermediate support and argue for defensive positioning — trim exposure to names showing repeated breakdowns and look for clearer trend recovery before adding risk.

Retail and Utilities diverged intraday: Retail rose 1.0% with Costco (COST) up 1.5% to $948.50, but the sector remains slightly below its 50-day (-2.4%), suggesting selective strength in dominant retailers. Utilities eked out a 0.2% gain with Duke Energy (DUK) up 1.0% to $118.76, holding +3.6% vs its 50-day average and serving as a safe-haven allocation amid the broader S&P 500 weakness. The 50-day context supports overweighting high-quality utility and select retail franchises for downside protection.

Breadth metrics and eight HIGH alerts argue for risk-off positioning into upcoming macro prints (U.S. Services PMI) and central bank decisions, with priority on trimming momentum exposures in Mag 7 names that show short-term weakness.
