SolarEdge Stock And 2 US Chip Plays Worth Watching After New Tariffs
The Trump administration’s new tariffs on polysilicon and related products have suddenly pushed the solar and semiconductor supply chain back into the spotlight. Costs, trade friction and shifting competitive pressures are all in play, which means some stocks could see fresh demand while others face new headwinds. This article walks through three U.S. listed companies exposed to this policy shift and explains how the news might influence their investment story.
The stocks discussed below are just a starting sample, and the full screen surfaced 30 more U.S. semiconductor and solar manufacturing companies with equally compelling narratives that are not covered in this article. To go broader and identify your own highest conviction angles, head straight into the U.S. Semiconductor and Solar Manufacturing screener.
Alpha and Omega Semiconductor (AOSL)
Overview: Alpha and Omega Semiconductor designs and supplies power chips that help manage and convert electricity inside everyday electronics, from smartphones and PCs to data centers, EV systems and industrial equipment, with a growing focus on higher value power management solutions for AI computing and graphics.
Operations: The company generates about US$685 million in revenue from designing, developing and supplying power semiconductor products, with most sales reported through Hong Kong and the rest spread across China, the United States, South Korea and other countries.
Market Cap: US$974 million
Alpha and Omega Semiconductor sits at the crossroads of the Trump administration’s new polysilicon tariffs and the rising need for power management in AI data centers. The company is still loss making and relies entirely on external funding, and analysts expect a sharp improvement in earnings and see scope for margins to benefit as higher value power ICs grow as a share of revenue. Recent products targeting AI servers, together with fresh board expertise in supply chain and operations, indicate that management is focusing on this opportunity while working through trade related uncertainty. The stock is priced below many semiconductor peers on sales multiples, and investors who can tolerate volatility may find the full story worth a closer look.
Alpha and Omega Semiconductor’s AI power story appears to be in its early stages, yet the stock still reflects considerable doubt in its pricing. Get the full context in the 2 key rewards and 1 important major warning sign and see what could shift this balance next.

SolarEdge Technologies (SEDG)
Overview: SolarEdge Technologies provides the hardware and software that sit at the heart of many solar energy systems, including power optimizers, inverters, home batteries, EV chargers and energy management tools that help households and businesses control how they produce and use electricity.
Market Cap: US$2.1b
SolarEdge Technologies sits at the intersection of new polysilicon tariffs and the push for more U.S. made clean energy hardware. The company already has a growing U.S. manufacturing footprint and has created nearly 2,000 domestic jobs, which management argues can help soften tariff impacts while supporting exports of U.S. made inverters and storage products. At the same time, SolarEdge is still working through weak residential demand, tariff related margin pressure, high share price volatility and reliance on external funding. Analysts currently project a move back to profitability, yet recent guidance cuts and legal settlements keep many investors cautious. If you are looking for a high variance solar hardware stock with a full home energy ecosystem, this is one to study more closely.
SolarEdge Technologies appears to be a stalled solar heavyweight with a U.S. manufacturing story that many investors may be underestimating. Get the full picture in the 2 key rewards and 1 important major warning sign
PDF Solutions (PDFS)
Overview: PDF Solutions provides software, data platforms, test hardware and services that help chip manufacturers monitor their factories, improve yields and coordinate complex production steps across the semiconductor supply chain.
Operations: PDF Solutions generates about US$231 million in revenue entirely from Software & Programming, with roughly US$111 million from the United States and the rest spread across China, Japan and other international markets.
Market Cap: US$2.1b
PDF Solutions operates at the intersection of new polysilicon tariffs and the broader push for onshore chip capacity, alongside the need for smarter manufacturing. Recurring software and analytics, including tools that use AI, are helping chip producers handle growing complexity. Earnings have been very strong recently, even as the stock trades at a premium P/S multiple that some investors will question. At the same time, reliance on external funding, customer concentration and exposure to evolving U.S. China rules around advanced nodes mean the story involves real risks. With Q2 2026 results due after the close today and fresh equity raised in May, investors tracking how higher U.S. wafer starts could feed into PDF Solutions’ data platforms may want to consider what the market might be overlooking next.
Accelerating software demand and premium P/S expectations place PDF Solutions at the center of the new onshoring push; yet many investors may be missing one crucial twist hiding in the 3 key rewards and 2 important warning signs
