Hydrogen Stocks Caught in a Contagion as Plug Power Rides the Sector’s Rollercoaster
Published on 07/26/2026 at 14:32 | Redaktion boerse-global.de
The selloff in hydrogen stocks on Friday had nothing to do with any single company’s fundamentals and everything to do with the mechanics of thematic investing. Plug Power closed at €1.84, shedding 4.63% in a single session, but the damage was far worse for its peers. Bloom Energy cratered 13%, FuelCell Energy dropped 9%, and the Global X Hydrogen ETF slid 5% to $42 — confirming that the pressure was sector-wide rather than company-specific.
What triggered the rout? Analysts point to profit-taking in what had become an overheated “AI power” trade. Bloom Energy and FuelCell Energy had rallied sharply in recent weeks, and Friday’s move looks like a classic unwind of crowded positioning. A short-seller report from early July that questioned Bloom Energy’s supply chain disclosures and triggered a class-action investigation continues to provide ammunition for bears whenever sentiment shifts.
Plug Power emerged as the least-battered of the three, but that’s cold comfort for investors watching the stock trade roughly 50% below its 52-week high of €3.72, reached on June 2. The stock now sits well below both its 50-day moving average of €2.52 and its 200-day moving average of €2.20. The 14-day relative strength index stands at 31.0, brushing against oversold territory, while annualized 30-day volatility has surged past 50%.
The ETF Structure That Binds Them
This isn’t an isolated incident. Plug Power has moved in lockstep with its higher-valued peers repeatedly this month, even in the absence of company-specific news. The reason lies in the architecture of thematic hydrogen funds. Bloom Energy represents 15% of net assets in the Global X Hydrogen ETF, Plug Power 9%, and FuelCell Energy 5% — together accounting for 29% of the fund. When one heavyweight wobbles, the others get dragged along regardless of their individual stories.
Should investors sell immediately? Or is it worth buying Plug Power?
The pattern is familiar. A similar profit-taking wave hit the sector in early July without any fresh corporate catalyst. Plug Power simply followed the broader hydrogen complex lower.
The Cash Story That Won’t Go Away
Beyond the sector noise, Plug Power’s fundamental challenges remain unresolved. The company burned roughly $150 million in operating cash flow during the first quarter of 2026 and held $223.2 million in free cash. The market is demanding visible cash generation, not survival milestones.
That’s where the Stream Data Centers deals come into focus. In February 2026, Plug Power signed a binding agreement to sell its stake in the Gateway project in New York to the data center developer, with gross proceeds of at least $132.5 million and potentially up to $142 million depending on the closing date. A second transaction followed in July: Stream is acquiring the Texas project in Graham — 66 acres of land with a 164-megawatt grid interconnection — for up to $76.5 million. Together, the two deals are part of an initiative expected to unlock more than $275 million in additional liquidity.
But the real prize lies beyond the sale proceeds. Stream and Plug Power are also discussing something far more consequential: the potential deployment of Plug’s fuel cell technology to power data centers. Those conversations remain preliminary — no contracts have been signed — but if they materialize into actual orders, the investment thesis would shift fundamentally. Plug Power would transform from a struggling materials-handling supplier into a power provider for the AI boom.
What to Watch This Week
No specific company catalyst is on the calendar for the coming days, leaving the stock at the mercy of two forces: progress on closing the Stream transactions and the broader risk appetite for volatile small-cap stocks.
Plug Power at a turning point? This analysis reveals what investors need to know now.
Technically, the 200-day moving average at €2.20 represents the first hurdle for any recovery attempt. To the downside, the 52-week low of €1.21 marks how much cushion remains if the selloff deepens.
For now, investors will continue watching Bloom Energy and FuelCell Energy to gauge where Plug Power is headed next — so tightly intertwined are the three names through thematic funds. Whether the sector can stabilize depends partly on whether Bloom Energy holds key support levels. All three companies report quarterly results in the coming weeks, which could provide fresh direction.
Until then, Plug Power’s next move hinges less on sector euphoria and more on whether the company can demonstrate tangible progress in generating cash — not just surviving, but proving it can thrive.
