The Hidden Stock Behind the AI Revolution
While everyone talks about NVIDIA, there's a company nobody knows — but every AI data center operator needs: Advanced Energy Industries (AEIS). They build the power systems that keep AI servers running. Without their tech: no ChatGPT, no Gemini, no Claude.
Here's what's interesting: In the last three months, 70 hedge funds entered new positions — up from 45. That's a 55% increase. Billions of dollars are flowing into a stock most people have never heard of.
But at the same time, something strange is happening: Baron Capital, one of the largest long-term holders, sold 60% of its position. Their reasoning: The stock hit its long-term price target and had grown too large in the portfolio.
What Does Advanced Energy Actually Do?
Imagine building a data center for AI training. Each GPU rack consumes 50 to 100 kilowatts — more than an entire house. If the power supply isn't perfect, the system crashes. Or worse: it catches fire.
Advanced Energy builds exactly these power systems — ultra-efficient, ultra-reliable. Their latest products achieve over 97.5% efficiency. That sounds like a detail, but with billions of servers worldwide, it saves hundreds of millions in electricity costs.
In Q2 2026, they generated $574 million in revenue — 30% more than last year. Their data center business doubled. Gross margin: 41% — unusually high for hardware.
Why Are 70 Hedge Funds Buying — While Baron Exits?
That's the fascinating question. The 70 new hedge funds likely see: AI infrastructure is booming, and Advanced Energy sits at a critical point in the supply chain. Every new data center needs their technology.
Baron Capital, on the other hand, says: We've made our money (over 10x return since entry), the stock is fairly valued, and we're taking profits.
Both can be right. Baron is a value investor — they buy cheap, sell fair. The 70 hedge funds are growth investors — they believe the AI boom has years to run.
What This Means For You
If you believe in AI but don't want to bet on whether NVIDIA or AMD wins — Advanced Energy is the "shovel in the gold rush." No matter which chip wins, everyone needs power.
But: The stock rose from $144 to $397 (52-week high) and now sits at $275. That means much of the growth is already priced in. Baron didn't sell without reason.
The question is: Is the AI boom big enough that even at fair valuation, there's still room to run? The 70 hedge funds believe yes. Baron believes no.
First Steps For Beginners
If this story interests you:
- Watch the quarterly numbers (next earnings call: November 2026). Is the data center business still growing?
- Monitor the competition: Are other companies entering this market?
- Check the valuation: AEIS has a P/E of 61 — that's expensive. Is it justified by growth?
And if you're unsure: Baron kept 40%. They didn't exit completely. That's a signal: "Good company, but no longer cheap."
