7 Best Semiconductor Equipment Stocks to Buy

Page 1 of 2

The semiconductor equipment industry is entering 2026 with a stronger demand backdrop than the broader cyclical slump of 2022-2023 suggested. Worldwide semiconductor manufacturing equipment sales rose 15% year over year to $135.1 billion in 2025, according to SEMI, supported by investment in advanced logic, memory, and AI-related capacity expansion. That matters because equipment suppliers sit close to the physical bottleneck of the AI buildout: no fabs, no advanced chips; no tools, no fabs. Tiny supply-chain goblin math, but expensive.

The outlook also remains constructive. SEMI expects global semiconductor equipment sales to keep climbing through 2027, with the market projected to reach a record $156 billion, helped by spending on AI accelerators, high-performance computing, premium mobile processors, test equipment, and advanced packaging. Gartner’s April 2026 semiconductor forecast provides additional context, projecting worldwide semiconductor revenue to exceed $1.3 trillion in 2026, driven by strength in memory pricing and AI-related demand.

For investors, this makes semiconductor equipment a more selective but still important part of the chip supply chain. The group includes companies tied to wafer fabrication, process control, test systems, packaging, and materials handling. As chipmakers expand and upgrade capacity for AI, high-bandwidth memory, advanced logic, and complex packaging, equipment suppliers remain central to the next leg of semiconductor investment.

Methodology

For this article, we screened U.S.-listed semiconductor equipment and materials stocks and ranked them by short interest as a percentage of float, with lower short float ranking higher on the list. Short float was used as the primary ranking metric because it indicates lower bearish positioning in a stock. We sourced short float figures from stockanalysis.com.

Why are we interested in the stocks that hedge funds pile into? The reason is simple: our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 498.7% since May 2014, beating its benchmark by 303 percentage points (see more details here).

7. Amtech Systems, Inc. (NASDAQ:ASYS)

Percentage of Short Float: 2.90%

Amtech Systems, Inc. (NASDAQ:ASYS) is one of the best semiconductor equipment stocks to buy.

On May 8, the company appointed Guy Shechter as president and chief operating officer, effective May 19. Amtech said Shechter has held commercial and general management roles at semiconductor equipment and advanced packaging equipment companies, including Yield Engineering Systems and Veeco Instruments. The company said his customer relationships and industry experience will be important as Amtech expands its portfolio around AI semiconductor packaging and assembly applications.

That leadership move followed a May 1 CFO appointment, where Amtech said Thomas Sabol’s experience would help the company scale during a period of demand for advanced packaging and enterprise board assembly equipment tied to the AI infrastructure buildout. The operating signal also supports the story: on May 7, Amtech said AI product demand drove 31% year-over-year revenue growth in its fiscal second quarter, with strong demand for reflow equipment used in AI applications and higher-margin AI advanced packaging solutions.

Amtech Systems, Inc. (NASDAQ:ASYS) provides equipment, consumables, and services for AI semiconductor device packaging, advanced wafer substrate fabrication, advanced packaging, electronics assembly, silicon carbide devices, silicon power devices, and related semiconductor applications.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
