NEW YORK, March 11, 2026 — Despite mounting macroeconomic pressures that have rattled technology sectors globally, a select group of AI infrastructure stocks has delivered remarkable gains over the past month. Analysis from Zacks Investment Research identifies five companies — Vertiv Holdings Co. (VRT), HubSpot Inc. (HUBS), Dell Technologies Inc. (DELL), Keysight Technologies Inc. (KEYS), and Cognex Corp. (CGNX) — that have not only surged recently but maintain strong fundamental outlooks. These selections, all carrying favorable Zacks Ranks of #1 (Strong Buy) or #2 (Buy), represent critical players in the AI hardware and software ecosystem whose performance defies broader market anxieties about AI trade continuity and geopolitical instability.
AI Infrastructure Stocks Weather 2026’s Perfect Storm
The technology sector entered 2026 facing significant headwinds. Concerns about whether the explosive AI growth narrative could sustain its momentum collided with renewed geopolitical conflicts in the Middle East. These conflicts triggered a surge in crude oil prices, raising fresh inflation concerns and casting doubt on the Federal Reserve’s ability to continue its interest rate cutting cycle. “We’re seeing a classic risk-off rotation in many tech names,” noted financial analyst Michael Chen of the Market Intelligence Group. “However, companies providing the essential physical and digital plumbing for AI — the infrastructure layer — are demonstrating remarkable resilience. Their demand is tied to actual deployment, not just speculation.” Despite the S&P 500 Technology Sector declining approximately 8% year-to-date, these five infrastructure-focused firms have posted an average gain of 18% over the last 30 days, according to Zacks data.
This divergence highlights a crucial market insight: while AI application software and consumer-facing tech may be volatile, the underlying infrastructure build-out continues apace. Data center construction, semiconductor testing, industrial automation, and enterprise software platforms form the backbone of the AI revolution. Investment in this backbone appears more insulated from short-term sentiment shifts, driven instead by multi-year corporate and governmental capital expenditure cycles. The timeline of AI adoption has shifted from experimental projects in 2024-2025 to scaled production deployments in 2026, creating concrete, measurable demand for infrastructure providers.

Expert Analysis: Why Infrastructure Remains a Safer Harbor
“The market is beginning to differentiate between AI hype and AI reality,” explains Dr. Sarah Jennings, a senior technology analyst at the Boston Research Institute. “Companies like Vertiv and Dell aren’t selling the promise of AI; they’re selling the physical servers, power systems, and cooling solutions required to run AI models at scale. That demand is contractually secured and visible for quarters ahead. It’s a more defensible business model in uncertain times.” This sentiment is echoed in institutional flows. Data from EPFR Global shows that while general technology sector funds have seen outflows, thematic funds focused on digital infrastructure have recorded consistent inflows throughout the first quarter of 2026.
The Zacks Rank system, which heavily weights earnings estimate revisions, confirms this analyst optimism. All five companies have seen consensus earnings estimates revised upward over the past 30 days—a powerful bullish signal. Vertiv’s current-year estimate rose 15%, Dell’s jumped 12.5%, Cognex’s improved 11.5%, Keysight’s increased 4.2%, and HubSpot’s edged up 0.3%. These revisions suggest that despite gloomy headlines, the fundamental earnings power of these infrastructure providers is strengthening.
Comparative Performance and Valuation Context
To understand their relative strength, it’s useful to compare these picks against the broader AI landscape and traditional valuation metrics. While mega-cap tech leaders like NVIDIA and Microsoft have seen volatile trading, these mid-cap and large-cap infrastructure players have shown steadier upward trajectories.
| Company (Ticker) | Zacks Rank | 1-Month Price Change | Forward P/E Ratio | Expected EPS Growth (Current Year) |
|---|---|---|---|---|
| Vertiv Holdings (VRT) | #2 (Buy) | +22.4% | 28.5x | +46.4% |
| HubSpot (HUBS) | #1 (Strong Buy) | +15.8% | 42.1x | +26.9% |
| Dell Technologies (DELL) | #2 (Buy) | +19.1% | 18.7x | +23.4% |
| Keysight (KEYS) | #1 (Strong Buy) | +16.3% | 24.3x | +16.9% |
| Cognex (CGNX) | #1 (Strong Buy) | +14.6% | 31.2x | +23.5% |
The table reveals several key insights. First, all five stocks significantly outperformed the S&P 500’s approximate 2% gain over the same period. Second, their valuation multiples, while not cheap, are generally supported by high expected earnings growth rates. Dell stands out with a sub-20 forward P/E ratio, suggesting the market may still be undervaluing its AI server transformation. The diversity of their P/E ratios also indicates investors are applying different valuation frameworks to hardware versus software infrastructure plays.
The Road Ahead: Catalysts and Risks for Q2 2026
The near-term trajectory for these stocks will hinge on several upcoming catalysts. First-quarter 2026 earnings reports, scheduled for April and May, will provide critical validation of growth estimates. Management commentary on order backlogs, particularly for Dell and Vertiv, will be closely scrutinized. Secondly, the Federal Reserve’s interest rate decision in May could impact the discount rate used to value future earnings, affecting higher-multiple stocks like HubSpot. Finally, any de-escalation in geopolitical tensions could reduce oil price volatility and remove a major overhang from the entire growth stock complex.
Risks remain palpable. A sharper-than-expected economic slowdown could cause enterprises to delay capital expenditure on AI infrastructure. Intensifying competition in the data center hardware space could pressure margins for Vertiv and Dell. Furthermore, if inflation proves stickier than anticipated, forcing the Fed to halt or reverse rate cuts, the valuation compression for technology stocks could resume, impacting even these resilient names. Investors should monitor the 10-year Treasury yield and the U.S. Dollar Index (DXY) as key macro indicators.
Institutional Perspective and Portfolio Strategy
Major asset managers are increasingly allocating to what they term “picks and shovels” AI plays. “Our focus has shifted from the hyperscalers to the enablers,” states a recent portfolio strategy note from BlackRock’s Technology Opportunities Fund. “We see more predictable cash flows and clearer visibility in the infrastructure layer.” For individual investors, financial advisors suggest a balanced approach. Rather than concentrating in a single name, building a basket of infrastructure stocks across different sub-sectors—power/cooling, servers, testing, software, automation—can provide diversified exposure to the AI build-out theme while mitigating company-specific risks.
Conclusion
The standout performance of Vertiv, HubSpot, Dell, Keysight, and Cognex in March 2026 underscores a pivotal investment thesis: the AI revolution is entering a deployment phase where infrastructure providers reap tangible, recurring benefits. While headlines focus on macro fears and AI hype cycles, these companies are executing on record order books and expanding their technological moats. Their favorable Zacks Ranks, driven by rising earnings estimates, offer a data-driven signal of continued upside potential. For investors navigating a complex market, these AI infrastructure stocks represent a compelling blend of growth exposure and relative defensive characteristics, grounded in the physical and digital foundations being laid for the next decade of technological advancement. The key watchpoint for the remainder of 2026 will be whether their exceptional operational execution can continue to outweigh broader economic uncertainties.
