Semis Lead As AI Wobbles; Tariffs and BOE Loom at the Open

Introduction#

U.S. equities enter Thursday’s session with a cautiously positive tone after a selective, semiconductor-led advance on Wednesday. According to Monexa AI, the S&P 500 (^SPX) closed at 6,796.29 ( +0.37% ), the Dow (^DJI) at 47,311.00 ( +0.48% ), and the Nasdaq Composite (^IXIC) at 23,499.80 ( +0.65% ), while the CBOE Volatility Index (^VIX) eased to 17.91 ( -0.56% ). The closing pattern underscores a theme investors have contended with for months: durable leadership in chips and hardware even as mega-cap AI bellwethers show bouts of profit-taking.

Overnight, macro and policy currents re-entered the narrative. European markets were muted with sterling steady into the Bank of England decision, and Eurostat data showed a surprise dip in Eurozone retail sales for September, challenging hopes for a consumption-led rebound, per Reuters. Headlines around U.S. trade policy and tariff authority also remained in focus after reports that the Supreme Court voiced skepticism over existing tariff frameworks in arguments this week, raising questions about potential knock-on effects for import-reliant and export-heavy sectors (major outlets summarized the debate; see broader sentiment context via Reuters. Within tech, coverage indicated that Apple may be nearing a roughly $1 billion per year deal to use Google’s Gemini model to overhaul Siri, according to Bloomberg. Meanwhile, Google-related announcements tied to data center expansion and AI investment continued to hit the tape, including plans flagged for Australia’s Christmas Island per Reuters.

Market Overview#

Yesterday’s Close Recap#

The prior session’s close captured the market’s selective risk-on tilt, led by semiconductors and hardware with notable internal dispersion in mega-cap AI. According to Monexa AI, Wednesday’s index and volatility closes were as follows:

Under the surface, semiconductors and storage outperformed, with Micron up sharply and storage names rallying, even as some AI infrastructure leaders saw follow-on profit-taking. According to Monexa AI, MU closed at 237.50 ( +8.93% ), STX at 275.77 ( +10.14% ), AMD at 256.33 ( +2.51% ), while NVDA slipped to 195.21 ( -1.75% ). Broader communication services strength was anchored by Alphabet—both GOOG at 284.75 ( +2.41% ) and GOOGL at 284.31 ( +2.44% )—and supported by META at 635.95 ( +1.38% ). Consumer discretionary participation included TSLA at 462.07 ( +4.01% ) and SBUX at 82.88 ( +4.12% ), while HD lagged, down to 373.84 ( -2.41% ).

Healthcare remained bifurcated with outsized event-driven moves—AMGN rallied to 319.86 ( +7.81% ), offsetting some pressure from sharp declines in ZBH to 87.55 ( -15.15% ) and HUM to 264.94 ( -6.01% ). Industrials displayed a cyclical tone: airlines gained—LUV at 31.62 ( +6.57% ), UAL at 96.65 ( +6.48% ), DAL at 58.54 ( +5.20% )—and building systems supplier JCI rose to 120.86 ( +8.84% ) even as select specialty names sold off, including AXON at 639.53 ( -9.43% ). Energy leadership skewed toward renewables and midstream, with FSLR at 277.39 ( +5.59% ), TRGP at 162.69 ( +5.25% ), OKE at 66.27 ( +3.05% ), and BKR at 47.04 ( +2.33% ), while XOM edged to 113.68 ( -0.40% ).

Overnight Developments#

Internationally, risk sentiment steadied after the prior day’s AI wobble, with Asia firmer and Europe mixed into central bank headlines. Coverage by Reuters noted that global markets stabilized as AI shares reversed some losses, though U.S. futures were modestly softer during European hours. Eurozone retail sales unexpectedly fell in September, per Eurostat data reported by Reuters, and U.K. equities were largely steady ahead of the Bank of England’s policy decision, with sterling near multi‑month lows. Separately, U.K. bank shares gained on reports they may avoid a punitive tax measure in the upcoming budget, according to overnight market coverage from major outlets.

In AI and cloud infrastructure, Google’s continued expansion plans and sovereign-linked data center initiatives remained in the headlines, including a powerful AI data center project on Christmas Island reported by Reuters. Apple’s potential deal to use Google’s Gemini model to revamp Siri, reported by Bloomberg, adds another layer to the competitive AI stack and could redirect near-term investor attention to ad-driven cloud infrastructure and model monetization at Alphabet. Meanwhile, commentary from Nvidia’s CEO on AI leadership and regulatory risks continued to circulate, with sentiment pieces summarized by Reuters highlighting valuation nerves and policy uncertainty as near-term variables.

Macro Analysis#

Economic Indicators to Watch#

As the session opens, policy and activity data from Europe will color early trading, with the Bank of England’s rate decision squarely in focus after a period of sterling weakness and subdued U.K. equity moves. The Eurozone’s retail sales decline in September, flagged by Reuters, complicates the growth narrative and could temper risk appetite in multinational consumer and industrial names tied to European demand. In the U.S., the equity tape remains highly sensitive to AI spending cadence and to the balance between growth leadership and the interest-rate backdrop, a dynamic that has intermittently pushed the VIX higher in recent sessions per Reuters.

While there were no major U.S. macro prints highlighted overnight in our feed, rate expectations and liquidity conditions continue to frame equity risk premia. Investor commentary has focused on the feedback loop between bond yields and growth equity performance—particularly if yields drift lower, which some strategists argue would tilt the setup back toward growth leadership.

Global/Geopolitical Factors#

Trade and tariff policy remain a key wildcard. Reports that the U.S. Supreme Court sounded skeptical of certain tariff mechanisms injected uncertainty into the policy outlook, with potential implications for import-intensive retailers and electronics, as well as export-oriented industrials and agribusiness. The legal and policy outcome is unsettled; nevertheless, the mere prospect of change is enough to recalibrate risk for companies with global value chains. We note that tariff speculation is an ancillary factor today, but the signaling effect may show up in relative moves among discretionary retailers, select industrial exporters, and materials exposed to cross-border flows.

In Europe, the combination of soft retail sales and a BOE decision could influence global duration risk and the dollar. For U.S. multinationals with high EMEA exposure, any currency swings or demand signals from these decisions will be notable inputs into Q4 guidance and positioning.

Sector Analysis#

Sector Performance Table#

According to Monexa AI, sector performance into Wednesday’s close showed cyclical leadership and selective defensives lagging:

Semiconductors and storage set the tone in Technology even as AI titans were mixed. According to Monexa AI, MU ( +8.93% ) and STX ( +10.14% ) led gains, while a reset in AI servers and networking pulled on certain names, including a notable decline in SMCI to 42.03 ( -11.33% ). The concentration risk remains front and center: a small percentage swing in mega-caps like NVDA can exert an outsized impact at the index level even when the group’s breadth is positive.

Communication Services leaned on ad-tech and search, with Alphabet’s dual share classes up more than two percent and META adding +1.38%. However, dispersion was evident, as LYV fell to 134.79 ( -10.59% ), likely reflecting idiosyncratic factors around events and live entertainment. In Consumer Cyclical, strength in auto, apparel, and travel contrasted with big-box variance: TSLA ( +4.01% ), LULU ( +4.31% ), MAR ( +3.98% ) and SBUX ( +4.12% ) supported risk appetite, while HD fell ( -2.41% ).

Healthcare’s mixed profile continued: large-cap biopharma momentum helped offset medtech drawdowns, with AMGN ( +7.81% ) and LLY at 925.81 ( +2.09% ) contrasted against ZBH ( -15.15% ) and HUM ( -6.01% ). Financials reflected a bifurcation between fintech/crypto-adjacent names and traditional lenders. Retail risk appetite showed up in HOOD at 142.48 ( +4.15% ) and COIN at 319.30 ( +3.90% ), while BAC slipped to 52.45 ( -2.04% ) and JPM advanced to 311.68 ( +0.79% ).

Energy and Materials favored renewables, midstream, and select commodities. Solar leader FSLR climbed ( +5.59% ); midstream names like TRGP ( +5.25% ) and OKE ( +3.05% ) outpaced the integrated majors as XOM ticked lower ( -0.40% ). In Materials, chemicals and mining found support—DD at 39.63 ( +4.95% ), IFF at 64.00 ( +4.08% ), and NEM at 81.63 ( +3.46% )—even as construction-linked coatings SHW lagged at 335.77 ( -2.10% ). Among Utilities and Power, merchant-tilted players including AES ( +5.76% ) and NRG ( +3.10% ) outperformed regulated peers like PEG at 79.86 ( -2.40% ).

Real Estate was essentially flat, with rate sensitivity and property fundamentals driving dispersion: data-center proxies were mixed—EQIX at 822.12 ( -0.94% )—while healthcare and storage REITs held up, with WELL at 186.35 ( +1.08% ) and PSA at 278.92 ( +1.05% ).

Company-Specific Insights#

Earnings and Key Movers#

The calendar still provides pockets of single-stock volatility. Buy-now-pay-later platform AFRM reports today. According to Monexa AI’s preview, consensus looks for revenue around the mid-$880 million range with EPS near the low double-digit cents, and the stock closed at 71.52 ( +0.15% ). With funding costs and rate sensitivity central to the model, traders will key on forward-loss rates, funding mix, and any guidance shifts.

AI infrastructure and datacenter adjacency remain active. IREN, whose AI cloud contract with Microsoft has elevated attention, rallied to 76.41 ( +14.68% ) and has seen upward revisions to its price targets in recent coverage. The setup continues to highlight market enthusiasm for compute capacity providers with renewable footprints and hyperscaler contracts.

In Energy retail and midstream, SUN closed at 52.55 ( +0.31% ) after an analyst upgrade to “Outperform” alongside a higher target. The broader energy tape’s tilt toward midstream and merchant-exposed names, plus a selective solar bid, reinforces the theme that investors are looking for defensible cash flows and secular growth tied to the power transition rather than pure commodity beta.

Healthcare featured stark event-driven moves. BHVN fell to 8.34 ( -40.19% ) following adverse FDA news outlined in market reports, underscoring the binary risk in clinical and regulatory pipelines. Elsewhere in therapeutics and medtech, discrete clinical updates in gene therapy and ophthalmology continued to generate stock-specific reactions across the small/mid-cap biotech cohort.

Small-cap AI edge compute also drew attention. OSS jumped to 5.76 ( +22.03% ) following an upgrade to Buy and a notable top-line beat with gross margins reported near the mid-30s, highlighting demand for ruggedized, high-performance edge computing solutions tied to autonomy and sensor processing.

Industrial policy and defense exposure were in motion. HII eased to 306.68 ( -2.92% ) despite constructive analyst stances, even as AUKUS-related collaboration headlines pointed to incremental long-cycle demand support. The defense complex remains a relative hideout on budget visibility but continues to trade on program cadence and supply-chain execution.

Finally, within the AI platform oligopoly, mega-cap reactions remain pivotal. MSFT at 507.16 ( -1.39% ) continues to balance outsized AI infrastructure capex with accelerating AI services demand; GOOGL and GOOG outperformed on ad momentum and model progress; NVDA remains the key index-level swing factor as investors digest supply, regulation, and competitive headlines. Media coverage from Reuters and WSJ this week framed the debate around the sustainability and timing of AI spending and the market’s valuation tolerance.

Extended Analysis#

AI concentration risk remains the through-line for U.S. equities. According to Monexa AI, Wednesday’s leadership skewed to semis and storage even as select AI infrastructure bellwethers slipped, a pattern consistent with recent sessions where hardware breadth offsets mega-cap digestion. Correlation analyses over the past quarter suggest that pullbacks in marquee AI names can precede broader risk-off episodes, with implied volatility gauges such as the VIX drifting higher during those windows, as flagged by Reuters. In this context, yesterday’s -0.56% move in VIX to 17.91 provides a measure of relief but does not resolve the underlying sensitivity to AI earnings cadence and policy risk.

A second, emerging axis is the power and infrastructure footprint required to support AI growth. Big Tech’s ongoing investments in data centers, network capacity, and energy sourcing—including reports of Google’s new AI data center planning in Australia’s Indian Ocean territory via Reuters—continue to pull in adjacent beneficiaries across midstream power, merchant generators, and nuclear operators. Names like CEG at 363.25 ( +0.12% ) and NRG at 173.19 ( +3.10% ) reflect investor interest in baseload and flexible generation, while nuclear’s resurgence is filtering into sentiment for specialized plays such as SMR at 37.91 ( +6.41% ).

Policy uncertainty—the third axis—has two immediate touchpoints: tariffs and central bank signaling. Reported Supreme Court skepticism on tariff authority introduces a potential medium-term variable for import-reliant retailers and electronics alongside export-heavy industrials and agriculture. Within Materials, DD ( +4.95% ) and ALB at 91.96 ( +3.97% ) illustrate how cyclical and energy-transition materials can still advance amid policy noise when demand indicators improve. In Consumer Defensive, dispersion persists: ADM slipped to 56.29 ( -6.37% ) even as packaged foods and beverages advanced—HSY at 169.88 ( +2.37% ) and TAP at 45.18 ( +3.46% )—reminding investors that commodity sensitivity and category dynamics can dominate day-to-day moves.

For Financials, the bifurcation between fintech/crypto-linked names and traditional banks remains intact, with HOOD ( +4.15% ) and COIN ( +3.90% ) showing persistent beta to risk-on phases even as large lenders diverge—BAC ( -2.04% ) versus JPM ( +0.79% ). Rate expectations and loan growth commentary, particularly into year-end outlooks, will remain the swing variables here.

Conclusion#

Morning Recap and Outlook#

Into Thursday’s open, the equity setup reflects a familiar equilibrium: a semiconductor-led advance with mixed mega-cap AI, a modestly lower volatility backdrop, and macro currents from Europe and the U.K. that could nudge global duration and FX. According to Monexa AI, the S&P 500 finished at 6,796.29 ( +0.37% ), the Nasdaq at 23,499.80 ( +0.65% ), and the Dow at 47,311.00 ( +0.48% ), with both the VIX and the small-cap volatility index (RVX) easing on the day. Sector leadership favored energy transition and midstream within Energy, cyclical transport and building systems in Industrials, and advertising/search within Communication Services; Healthcare and Consumer Defensive were mixed, and Real Estate was rate-sensitive and dispersed.

The primary near-term catalysts are clear. First, the Bank of England decision and Eurozone demand signals provide a read-through on global growth and rates; second, U.S. tariff policy uncertainty persists as courts and policymakers debate the scope and design of trade tools; third, AI infrastructure headlines continue to steer relative performance among hyperscalers, chipmakers, and power infrastructure names. On the micro side, AFRM earnings will test rate-sensitive consumer fintech, while flows into compute capacity and edge hardware cast a favorable light on adjacent beneficiaries like IREN and OSS.

For portfolio construction, the message is discipline. Concentration risk around AI remains elevated; even with broad chip strength, a small decline in NVDA can blunt index gains. Rate and policy sensitivity are most acute in Financials, Real Estate, and import-exposed retail lines, while commodity and power exposures are benefitting from the energy transition bid. Position sizing around high-conviction AI beneficiaries, selective exposure to midstream and merchant-power names, and stock-specific diligence in Healthcare and Consumer Defensive look prudent given the day’s catalysts.
