The S&P 500 climbed 1.80% to 771.33, while the Nasdaq-100 surged 3.40% to 723.85, as AI and technology shares caught a strong bid. Our 524‑stock AI infrastructure universe outperformed, advancing 432 names with an average gain of 3.40% — 1.60 percentage points ahead of the SPX. Networking led all segments at +7.65%, while Utilities & Energy barely budged, adding just 0.09%. MOVE (Corvex, Inc.) was the session’s standout, jumping 27.6%, and BRKR (Bruker Corporation) slid 21.8% to lead decliners despite beating the consensus estimate. Today is heavy on macro and micro: ADP employment, ISM Services, and a parade of earnings that includes AMD’s beat after yesterday’s close, this morning’s numbers from GlobalFoundries, Materion, and Avnet, and the opening of a dense Wednesday–Thursday slate headlined by DDOG, NVMI, CEG, and VST.

AMD (Advanced Micro Devices, Inc.) reported Q2 adjusted EPS of $1.66, a $0.04 beat versus the $1.62 consensus. The data‑center CPU and GPU portfolio remains a direct read on AI infrastructure spend, and the upside adds to evidence that hyperscale capex is still flowing into high‑end compute.

ANET (Arista Networks, Inc.) delivered EPS of $1.02, $0.13 above estimates. The result underscores the strength of AI‑driven network upgrades across cloud and enterprise data‑center environments.

ALAB (Astera Labs, Inc.) posted $0.80, topping the $0.69 estimate by $0.11. The intelligent‑connectivity provider is tightly linked to AI rack‑scale deployments, and the beat hints at steady demand for CXL memory‑interface and PCIe retimer products.

ENTG (Entegris, Inc.) earned $0.93, an $0.11 beat, pointing to robust consumption of advanced materials and contamination‑control solutions in leading‑edge semiconductor production.

CAT (Caterpillar Inc.) crushed the $6.22 estimate with $8.17, a $1.95 beat. The out‑sized result likely reflects heavy data‑center construction and power‑generation equipment demand alongside broad infrastructure activity.

CMI (Cummins Inc.) missed by $0.48 with EPS of $6.73 against a $7.21 estimate, suggesting softer industrial power‑generation orders outside the data‑center channel.

DBRG (DigitalBridge Group, Inc.) blew past the $0.04 consensus, reporting $1.15. The digital‑infrastructure investment platform benefited from asset‑sale gains and strong returns on its data‑center holdings.

TSEM (Tower Semiconductor Ltd.) delivered $0.88, a $0.12 beat, reflecting healthy foundry utilization for the analog and power‑management chips that feed AI servers and infrastructure.

LUMN (Lumen Technologies, Inc.) posted a narrower‑than‑expected loss of –$0.07, a $0.06 beat, signaling improving trends in fiber‑network demand.

This morning, GFS (GLOBALFOUNDRIES Inc.) released Q2 financial results. The foundry supplies networking and power‑management semiconductors, making it a bellwether for AI‑adjacent chip fabrication. MTRN (Materion Corporation) announced record Q2 numbers and raised its full‑year outlook, signaling broad advanced‑materials demand from semiconductor and industrial applications. AVT (Avnet, Inc.) reported fourth‑quarter and full‑year fiscal 2026 results, offering a view into the component‑distribution channel that underpins board‑level AI hardware. EOSE (Eos Energy Enterprises, Inc.) tightened full‑year revenue guidance and disclosed that Frontier Power USA closed a $263 million capital raise for an 800 MWh BESS project, underscoring the scaling of long‑duration storage for grid‑connected data centers.

→ AMD’s data‑center strength could be a positive signal for advanced packaging and test demand — companies such as AEHR (burn‑in and test systems) and packaging‑equipment names may see follow‑on orders as higher‑end GPU volumes ramp.

→ ANET’s beat reinforces the networking upgrade cycle that supports AI clusters, which could buoy optical‑component demand at transceiver makers such as AAOI and LITE, both of which compete with one another and serve large cloud networks.

→ ALAB’s CXL and PCIe retimer momentum suggests accelerating memory‑interface adoption, which may lift demand for complementary memory IP and connectivity silicon from companies such as RMBS and CRDO.

→ ENTG’s beat points to healthy consumption of advanced materials, a potential positive read‑through for specialty chemicals and gases used in wafer processing; names such as CC and ALB could see indirect support.

→ CAT’s enormous beat could foreshadow sustained data‑center construction spending, potentially benefiting steel and structural‑materials firms such as CMC and engineering contractors like PRIM and ECG.

→ TSEM’s beat indicates solid foundry utilization for analog and power‑management semiconductors, a modest positive for chip‑equipment suppliers such as AMAT and LRCX that outfit those fabs.

→ MTRN’s record quarter and raised outlook may be an early sign of broadening advanced‑materials intensity in semiconductor manufacturing, a trend that could indirectly support materials‑delivery and process‑control providers such as AME and MKSI.

CMC hosts Investor Day, unveils long‑term targets and a $600 million buyback increase. CMC (Commercial Metals Company) positioned itself as an early‑stage construction‑solutions provider, released long‑range financial goals, and authorized an additional $600 million in share repurchases. CMC is a key supplier of rebar and steel products to data‑center concrete and structural work, so the bullish messaging suggests confidence in the multi‑year data‑center construction pipeline.

→ CMC’s investor‑day tone and buyback announcement signal confidence that data‑center structural demand will remain elevated, which could lift expectations for engineering and construction firms such as PRIM and ECG that execute data‑center builds.

Datadog (DDOG) reports Thursday. The observability platform is a direct pulse on cloud‑AI infrastructure spending; its consumption‑based model will shed light on GPU‑accelerated workload adoption and overall hyperscaler investment velocity.

Nova (NVMI) and Onto Innovation (ONTO) both deliver results this week. These metrology and inspection‑equipment makers are critical to advanced packaging for high‑bandwidth memory and chiplet architectures, and their reports will provide a window into the health of the packaging‑equipment cycle.

Constellation Energy (CEG) and Vistra (VST) report on Thursday and Friday, respectively. As nuclear‑ and gas‑fired independent power producers, they sit at the center of the data‑center power‑procurement wave and will offer color on forward power‑purchase agreements and interconnection pipeline progress.

AAOI reports Thursday. The optical transceiver vendor will give a direct signal on 400G/800G data‑center demand; its results could move the entire networking segment and have implications for a broad set of AI‑infrastructure component suppliers.
