Plug Power’s Oversold RSI Contradicts 52-Week High: Options Bet on $4.50 Breach Ahead of UK Hydrogen Milestone

Plug Power's RSI plunges to 20 as options traders pile into $4.50 calls ahead of weekly expiry, fueled by Barrow green hydrogen FID and improving Q1 2026 earnings.

The tug-of-war between technical exhaustion and fundamental momentum is playing out sharply in Plug Power’s options chain. With the stock hovering near €3.56 after hitting a fresh 52-week high just a day earlier, the relative strength index has plunged to around 20 — a level that typically signals oversold territory rather than overbought fatigue. Yet the options market is pricing in anything but a pause. On Wednesday evening, over 20,000 call contracts changed hands at the $4.50 strike, with open interest nearly matching that volume. The equivalent put strike saw only 206 trades. The message is unambiguous: speculators are positioning for a 26% leap through the $4.50 barrier before Friday’s weekly expiry.

That conviction isn’t floating on thin air. Just two days earlier, on May 27, Plug Power announced that its Barrow Green Hydrogen project in Cumbria, England, had secured a final investment decision, shifting from planning into construction. The facility, run by the Green Hydrogen Energy Company — a joint venture between Schroders Greencoat and Carlton Power — will use six 5 MW GenEco electrolysers supplied by Plug, generating around 100 GWh of green hydrogen annually. The output will flow directly to Kimberly-Clark’s local plant, home to brands like Andrex and Kleenex, and is expected to cut the factory’s natural gas consumption by up to 50%, displacing roughly 18,300 tonnes of CO? per year.

Barrow is the first of three UK projects Plug Power is backing; Trafford and Langage remain in earlier stages, awaiting final investment decisions. The company sees these developments as a blueprint for industrial decarbonisation across Europe. Meanwhile, its own financial trajectory is improving. First-quarter 2026 revenue rose 22% year-on-year to $163.5 million, and GAAP gross margin tightened from minus 55% to minus 13%. The net loss per share narrowed to $0.18 from $0.21, though that figure includes roughly $140 million in non-cash charges tied to convertible notes and warrant valuations. The balance sheet held over $802 million in cash at quarter-end, of which $223 million was unrestricted. The remaining $579 million, still restricted, is expected to be released at a rate of about $50 million per quarter over the next several years.

The overarching question is whether Plug can sustain its operational recovery and deliver on its own target of positive EBITDAS by the fourth quarter of 2026. The Barrow project provides a tangible proof point, and the options surge suggests at least a faction of the market believes the stock can reclaim the $4.50 level in the very near term. Given the stock’s annualised volatility of nearly 100%, a squeeze through that strike is far from implausible — but Friday’s expiry will test whether the oversold condition actually precedes a bounce or simply marks another pause in a high-beta ride.
