Markets just had a sharp mood shift after the US and Iran agreed an interim deal that reopened the Strait of Hormuz, lifting US equity futures and pulling oil below US$78 a barrel, while the Federal Reserve kept rates on hold but sounded ready to tighten again if needed. For large US technology stocks with solid balance sheets and strong potential scores, this combination of improved risk sentiment and a still firm rate backdrop can matter a lot for valuations and earnings sensitivity. This article highlights 3 US Large Cap Technology stocks that stand out as positively exposed to this news-driven setup.

NVIDIA (NVDA)

Overview: NVIDIA is a US-based semiconductor and software company that designs graphics processing units and full AI computing platforms used in data centers, gaming PCs, professional visualization and automotive systems worldwide.

Operations: NVIDIA generates about US$25.1b from its Graphics segment and US$228.4b from Compute & Networking, with revenue concentrated in the United States at roughly US$187.7b and further sales across Taiwan, China including Hong Kong and other countries.

Market Cap: US$4,956.2b

For investors looking at large cap AI exposure, NVIDIA sits at the heart of the current risk-on mood, with mega projects in Saudi Arabia and the U.A.E. tied directly to US-led AI infrastructure, record data center revenue and very high profitability. The company has strong earnings momentum and sizeable shareholder returns through buybacks and dividends, yet also faces real pressure from export controls, high capital needs for customers and intensifying GPU competition. With the Fed still signaling higher for longer rates and tech leading the latest futures rally, the mix of growth, rich margins and policy risk makes NVIDIA a stock you may not want to gloss over, especially if you care about how AI and geopolitics intersect.

NVIDIA’s AI projects in Saudi Arabia and the U.A.E. plus record data center revenue are only half the story; the real twist sits in the 4 key rewards and 2 important warning signs (1 is major!)

Splunk (SPLK)

Overview: Splunk is a US software company that helps organisations monitor, secure and understand their digital systems by collecting and analysing machine data across cloud, on-premise and hybrid environments.

Operations: Splunk generates about US$4.2b in revenue from developing and marketing its cloud services and licensed software solutions.

Market Cap: US$26.4b

Splunk stock sits in the slipstream of the renewed interest in large US tech, with its security and observability tools directly tied to the data infrastructure that can benefit when sector risk appetite improves. The company is now profitable, yet it carries a high P/E and a sizeable debt load, so a lot of optimism is already priced in and funding risk cannot be ignored. Recent partnerships with Gigamon, IPinfo and Resecurity show how deeply Splunk is wiring itself into security and observability workflows, which can strengthen its position if management executes well despite relatively short tenure at the top.

Splunk’s accelerating shift to profitability with security and observability wired into core workflows is only part of the story; the real tension between growth and that high P/E sits inside the 3 key rewards and 3 important warning signs

Amphenol (APH)

Overview: Amphenol is a US-based manufacturer of electrical, electronic and fiber optic connectors and sensor systems that sit inside everything from AI data centers and communications networks to cars, aircraft and industrial equipment.

Operations: Amphenol generates about US$14.3b from Communications Solutions, US$6.4b from Harsh Environment Solutions and US$5.5b from Interconnect and Sensor Systems, with an intersegment adjustment of US$311.1m.

Market Cap: US$195.4b

Amphenol provides exposure to the plumbing of AI and cloud, supplying high speed interconnects into IT datacom and AI data centers while also serving auto, aerospace and industrial customers, which can steady revenue when one segment cools. Recent earnings growth of 70.9%, high margins and a ROE near 32% indicate characteristics of a high quality business, supported by strong free cash flow and acquisitions that expand its fiber and RF capabilities. At the same time, a P/E above the US electronic industry average, high leverage and heavy spending to keep up with AI demand mean execution and balance sheet discipline are important, particularly with traders now able to use new 2x ETFs tied to Amphenol’s stock.

Amphenol’s high margins, rapid recent earnings growth and strong free cash flow suggest more is going on beneath the surface, but the real story of future demand and concentration risk sits inside the analyst forecasts for Amphenol
