Zacks/Yahoo/Nasdaq-style earnings previews and reviews across sectors

Company Earnings Estimates & Surprises

The 2026 Q4 earnings season continues to reinforce the striking bifurcation in market dynamics: AI infrastructure and hyperscaler-linked companies remain the strongest growth engines, consistently delivering earnings beats, raising guidance, and catalyzing upward revisions in analyst estimates. Meanwhile, broader sectors—especially cyclical and adjacent industries—face ongoing challenges from uneven demand, margin pressures, and macroeconomic and geopolitical headwinds. Recent results and market reactions further emphasize the critical role of Zacks Earnings ESP (Expected Surprise Prediction) and consensus estimate revisions as powerful tools for anticipating earnings surprises and guiding tactical investment decisions.

Reinforcing the AI Infrastructure Growth Narrative

Several key players in semiconductor manufacturing, equipment, and cloud infrastructure have reported strong results that underscore the secular growth driven by AI adoption:

Micron Technology (MU) again delivered a standout quarter, beating revenue and EPS estimates while raising its full-year outlook. The company highlighted sustained strength in high-bandwidth memory demand, a cornerstone for AI workloads. Reflecting this bullish momentum, Micron’s consensus EPS estimates have surged more than 17% over the past month, signaling growing analyst conviction.
Applied Materials (AMAT) reported robust earnings and raised guidance by 17%, fueled by accelerating semiconductor equipment orders from AI chipmakers. CEO Gary Dickerson emphasized the capital-intensive nature of AI hardware production as a long-term growth driver, noting, “We are witnessing unprecedented investment in AI chip fabrication, which underpins our optimistic outlook.”
Arista Networks (ANET) posted an earnings beat driven by hyperscaler spending on AI infrastructure expansion. Multiple analyst firms have upgraded and increased price targets following the results, citing Arista’s strategic positioning in high-speed networking solutions critical for cloud AI deployments.
TD SYNNEX (SNX) reported strong results linked to hyperscaler supply chains and received positive Earnings ESP signals, prompting renewed analyst enthusiasm. As a major distributor of AI hardware components, TD SYNNEX is well placed to benefit from ongoing infrastructure buildouts.
CoreWeave (CRWV), a niche AI cloud service provider, showed impressive revenue growth but disappointed on margin expansion, leading to an 8.1% post-earnings share decline. Nonetheless, Cathie Wood’s recent $3.46 million insider purchase signals selective long-term confidence in CoreWeave’s AI specialization despite near-term volatility.

Mixed Results Across Broader Sectors and Selective Strength

Outside the AI infrastructure cohort, earnings outcomes have been more uneven, reflecting persistent macroeconomic uncertainties and sector-specific headwinds:

The Trade Desk (TTD) reported results broadly in line with expectations, showing steady demand for programmatic advertising. Though not a direct AI play, The Trade Desk’s resilience amid cautious advertising budgets highlights pockets of stability in digital media.
Penumbra (PEN) surpassed consensus on revenue and EPS, driven by sustained medical technology demand. Analysts have upgraded PEN shares and raised estimates, expecting continued momentum.
On the downside, MKS Instruments (MKSI) missed EPS estimates, weighed down by semiconductor capital spending uncertainties and geopolitical tensions disrupting equipment orders.
United Airlines (UAL) posted encouraging signs of travel demand recovery, with earnings estimates moving higher supported by easing pandemic restrictions and growing passenger volumes.
Emerging software player Amplitude, Inc. (AMPL) reported mixed results, with revenue slightly beating but EPS missing by 9%, underscoring challenges in navigating shifting customer demand and competitive pressures.
Consumer discretionary names like Sweetgreen (SG) and Domino’s Pizza (DPZ) continue to reflect mixed consumer spending trends, balancing inflationary pressures against pockets of resilience.

Earnings ESP and Estimate Revisions: Sustained Predictive Power

Market participants increasingly rely on Zacks Earnings ESP and consensus estimate revisions as robust indicators for anticipating earnings surprises:

Fastly (FSLY) exemplifies this trend, with consensus EPS estimates rising over 31% in the past month alongside a positive Earnings ESP, indicating a strong probability of beating earnings expectations.
Other names such as Alkermes (ALKS), Nicolet Bankshares (NIC), and Rush Street Interactive (RSI) combine positive Earnings ESP readings with meaningful upward estimate revisions and insider buying, reinforcing favorable outlooks.
Historical data confirms that stocks ranked Zacks 1-3 with positive Earnings ESP beat earnings roughly 70% of the time, highlighting the statistical reliability of these tools for tactical trading and portfolio positioning.

Market Reaction and Sentiment: Selective Optimism Amid Persistent Volatility

Investor sentiment remains cautious and nuanced, reflecting mixed earnings outcomes and ongoing macro and geopolitical uncertainties:

The pronounced post-earnings selloff in CoreWeave despite strong revenue growth highlights investor focus on margin pressures and execution risks within emerging AI cloud providers.
Elevated hedging activity, including increased put option buying, is interpreted by some strategists as a contrarian signal, potentially marking buying opportunities in AI infrastructure and growth sectors.
Broader equity markets have traded in a narrow range with choppy intraday volatility as investors digest mixed earnings, conservative guidance, and geopolitical developments.
Analyst upgrades following earnings releases for hyperscaler-aligned firms such as Arista Networks and TD SYNNEX underscore continued market preference for companies deeply embedded in AI infrastructure buildouts.

Upcoming Reports and Sector Watch

Dell Technologies is anticipated to report soon, with expectations for steady results driven by corporate IT refresh cycles and incremental AI adoption.
Block (SQ) faces heightened scrutiny to demonstrate sustainable growth amid intensifying fintech competition and evolving payment ecosystems.
Consumer discretionary names remain in focus as bellwethers for spending trends, with early indications pointing to ongoing inflationary headwinds balanced by pockets of consumer resilience.

Tactical Investor Takeaways

Leverage Earnings ESP and Estimate Revisions as critical tools to anticipate earnings surprises and identify tactical entry points—especially in volatile or fast-evolving sectors like AI infrastructure.
Focus on Hyperscaler-Aligned AI Infrastructure Leaders such as Micron, Applied Materials, Arista Networks, and TD SYNNEX, which continue to benefit from secular AI-driven growth and strong analyst sentiment.
Exercise Selectivity within the broader AI cloud and adjacent sectors; companies like CoreWeave face margin and execution challenges, underscoring the importance of detailed company-level analysis.
Prepare for Continued Volatility, with earnings seasons producing divergent stock reactions and intraday swings. Employ tactical hedging and disciplined position sizing to manage risk effectively.
Monitor Insider Activity and Analyst Upgrades closely, as recent insider buying (e.g., Cathie Wood in CoreWeave) and fresh upgrades provide valuable directional cues for tactical portfolio adjustments.

Conclusion

The 2026 Q4 earnings season further crystallizes a pronounced market bifurcation: AI infrastructure and hyperscaler demand remain the dominant engines of earnings beats, estimate upgrades, and positive sentiment, while many adjacent and cyclical sectors wrestle with uneven demand, margin pressures, and macroeconomic headwinds. Incorporating Zacks Earnings ESP and consensus estimate revisions into research frameworks continues to offer investors a statistically validated edge in anticipating earnings surprises. Those focusing on well-positioned hyperscaler-aligned firms—and applying disciplined risk management—are best poised to navigate the ongoing market volatility and capitalize on the secular growth embedded in AI and semiconductor ecosystems.
