New US tariffs on major trading partners and a proposed 100% levy on imported semiconductors are reshaping the risk and reward profile for chip investors almost overnight. Higher import costs, potential trade friction, and shifting supply chains are pushing attention toward US Domestic Semiconductor Manufacturers that design and build more inside US borders. This article explains how that tariff shock may affect the sector and highlights 3 US semiconductor stocks from the screener that appear positioned to be positively exposed to the news, helping you assess where risk and opportunity might be clustering right now.

Veeco Instruments (VECO)

Overview: Veeco Instruments supplies highly specialized equipment that chipmakers and electronics manufacturers use to process wafers and build devices such as logic chips, memory, photonics components, power electronics, and radio frequency parts.

Operations: Veeco generates about US$655.3 million in revenue from a single core activity, the development, manufacture, sale, and support of semiconductor and thin film process equipment, with sales spread across China, the rest of Asia Pacific, the US, and EMEA.

Market Cap: US$3.2b

Veeco Instruments sits at the heart of US-based semiconductor manufacturing, supplying tools used in areas like AI data centers, advanced packaging, and compound semiconductors, and recently announcing more than US$250 million of new orders tied to high speed optical interconnects. Analysts currently rate the stock highly and see significant potential over the long term, yet the shares trade on a rich P/E and the company has a history of volatile margins, while tariffs and customer concentration in China add another layer of policy risk that management is actively working to offset. With insider selling at multi year highs and fresh index inclusions increasing visibility, investors looking at Veeco are weighing growth drivers against valuation, funding, and trade-related uncertainties that may not be fully reflected in headline numbers.

Veeco’s rich P/E, fresh index attention, and those US$250m high speed interconnect orders hint at a bigger story that many investors may be missing, and the real twist sits in the analyst forecasts for Veeco Instruments

Allegro MicroSystems (ALGM)

Overview: Allegro MicroSystems designs and manufactures sensor and power integrated circuits that help control motion, manage power, and measure current in complex systems, especially in cars, industrial equipment, and AI data centers. Its chips sit inside things like electric vehicles, braking systems, robotics, and energy infrastructure, where precise sensing and efficient power use are critical.

Operations: Allegro generates about US$890.1 million in revenue from a single core activity, the design, development, production, and distribution of integrated circuits, with sales spread across regions including Greater China, Other Asia, Japan, Europe, South Korea, the US, and the rest of the Americas.

Market Cap: US$8.7b

Allegro MicroSystems is drawing attention because its sensors and power chips sit at the intersection of US-focused semiconductor policy, vehicle electrification, and AI-heavy data centers, yet the stock mixes strong growth expectations with real execution and valuation questions. Analysts see robust revenue and earnings expansion and point to new ASIL-D power management products for brake-by-wire, increasing AI data center demand, and improving gross margins as key drivers. Recent guidance and price target hikes suggest confidence in that trajectory. At the same time, Allegro is still loss-making, trades on a rich P/S, faces intensifying competition in China, and remains heavily tied to the automotive cycle. The key issue for investors is how those growth and tariff tailwinds compare with pricing pressure, insider selling, and share price volatility.

Allegro MicroSystems sits where electrification, AI data centers, and tariffs intersect, yet the real story may be how expectations line up against its valuation and competition pressures in China, which the analysis report for Allegro MicroSystems starts to unpack before raising a bigger question investors rarely ask

Power Integrations (POWI)

Overview: Power Integrations designs and supplies high-voltage power conversion chips that sit inside everyday appliances, electric vehicles, AI data centers, renewable energy equipment, and industrial systems, helping turn wall-socket electricity into the stable power those devices need.

Operations: Power Integrations generates about US$446.3 million in revenue primarily from integrated circuits and related components for high-voltage power conversion, with sales spread across regions including Hong Kong/China, Korea and other Asia-Pacific markets.

Market Cap: US$3.9b

Power Integrations stands out in the US Domestic Semiconductor Manufacturers screener because it couples high-voltage GaN leadership and exposure to EVs, AI data centers, and industrial power with a clear domestic-manufacturing angle at a time when tariffs are pushing buyers toward US-centric supply chains. At the same time, the company is wrestling with softer appliance demand, earnings volatility, a rich P/S multiple, and heavy exposure to trade policy and housing-sensitive consumer products. Analysts also highlight new AI-focused designs and index inclusion as potential supports. The tension between that growth story and the current risk profile is where the most important questions for investors sit, and it is not fully visible in headline numbers.

Power Integrations’ GaN story and AI, EV, and industrial exposure suggest something bigger may be building under the surface, but the real tension between opportunity and policy risk sits inside the analyst forecasts for Power Integrations
