Plug Power has reached a milestone that hydrogen bulls have long awaited: a 5-megawatt PEM electrolyzer in Esbjerg, Denmark, is now producing green hydrogen at the Måde site, with annual capacity of roughly 550 tonnes. The company’s Australian Hunter Valley Hydrogen Hub, a 50 MW project developed with Orica, also secured a final investment decision. Yet the stock continues to slide, trading around €1.93 after shedding nearly 16.5% over the past week and more than 19% over the past month. The disconnect between operational progress and market reception is stark, and a key reason sits in the short book.
Around 27.4% of Plug Power’s freely traded shares are currently sold short. That concentrated bearish positioning creates persistent selling pressure that overrides the typical technical signals of a rebound. The 14-day relative strength index stands at 26.7, deep in oversold territory — a level that often precedes a bounce. But the RSI has been flashing that signal without any follow-through, because short sellers are doubling down rather than covering. Many traders appear to be positioning ahead of the next earnings report, betting that the company’s cash burn story will outweigh any project wins.
That skepticism is echoed by Wall Street. Susquehanna analyst Biju Perincheril cut his price target from $3.75 to $2.50 in early July, while keeping a Neutral rating. Morgan Stanley also trimmed its view, raising its target only modestly from $1.50 to $1.65 while maintaining an Underweight recommendation, citing persistent capital needs and negative free cash flow. The consensus analyst target sits near €3.17, implying roughly 64% upside from current levels — a spread that underscores just how divided opinion is on whether Plug Power can turn its pipeline into positive cash flow.
Should investors sell immediately? Or is it worth buying Plug Power?
On the operational side, the company has made measurable progress. GAAP gross margin improved from minus 55% to minus 13% in the most recent quarter, while revenue climbed 22% year-over-year to $163.5 million, driven by electrolyzer and material-handling segments. The Esbjerg installation and the Hunter Valley order demonstrate that the build-out is real. But each new contract adds scale without yet changing the fundamental math: Plug Power still consumes cash at a rate that forces it to monetize tax credits from projects like St. Gabriel and Georgia as a liquidity tool rather than a growth lever.
Technically, the stock is now trading 28.7% below its 50-day moving average of €2.71, and roughly 48% off the 52-week high of €3.72 set in early June. The 200-day average of €2.26 has flipped from support to resistance, sitting 14.5% above the current price. Annualized 30-day volatility is running at 59%, a level that often accompanies either capitulation or another leg lower. The year-to-date picture is still positive — the stock is up around 43% — but that reflects a violent swing earlier in 2025 rather than sustained momentum.
The next major catalyst arrives on August 10, 2026, when Plug Power reports second-quarter results. Investors will be watching closely to see whether the margin improvement from the first quarter can be repeated, and whether management offers a clearer timeline for reaching positive cash flow. Until then, the standoff between operational deliverables and a 27% short interest is likely to keep the stock in a high-volatility holding pattern, where every project milestone is met with a fresh round of bearish positioning rather than relief.
