Further Price Surges Possible — But Volatility Remains Extreme! What Investors Need to Know About Ballard Power Systems, ITM Power, and HPQ Silicon

Turbulent Times at Ballard Power

Ballard Power has entered turbulent waters, despite—or perhaps because of—the recent rise. In mid-May 2026, major Chinese shareholder Weichai Power dumped 8.15 million shares onto the market. This sale brought Weichai approximately CAD 46.07 million. Almost as serious, however and resulting from this, is the complete withdrawal of Weichai's directors from the supervisory board. As a result, the group loses its "strategic anchor" on the supervisory board. This put the stock under some pressure. However, the company announced new orders from Solaris and Wrightbus for the FCmove-SC drive technology; even these successes pale in comparison to the latest figures. Revenue for the first quarter of 2026 fell short of expectations. With revenue of approximately USD 19.4 million, the company reported a net loss of around USD 11.4 million. While the gross margin improved to 14%, with a market valuation of nearly CAD 1.75 billion, Ballard is far from sustainable profitability. While there is a significant gain over a 30-day period, the extreme volatility of over 100% and a Relative Strength Index well above 70 following the rise demonstrate the prevailing strength, but also the nervousness. Setbacks are likely and could be used as an opportunity to re-enter the market. Nevertheless, this is highly risky, as the stock has doubled in value without any such major positive change in fundamentals.

Decisive Days for ITM Power

While Ballard is still grappling with the loss of its partner, a completely different dynamic prevails at its British competitor, ITM Power. All eyes are fixed on May 26, 2026. On that date, the British Subsidy Advice Unit (SAU) is set to rule on a £46.5 million funding package. This money will go toward expanding the automated production line for the Chronos system in Sheffield. If approved, ITM could triple the output of its electrolyzers and reduce costs by 40%. On May 29, the company will also be added to the MSCI United Kingdom Small Cap Index, which will force passive index funds to buy shares. The institutional investor community is divided. Morgan Stanley upgraded the stock to "Overweight" and raised its price target to 170 pence, while UBS remains skeptical. The half-year results also reflect this mixed picture. Revenue climbed to £18 million, and the order backlog grew to a substantial £152 million. Nevertheless, the pre-tax loss widened to £45.4 million in the past fiscal year. On a positive note, the company has a well-stocked war chest with cash and cash equivalents of approximately £170 million. In addition, a new 10-year service contract for Milford Haven secured through the subsidiary Hydropulse ensures predictable revenues. After a sharp rise of well over 100% from a standstill and a high of just over EUR 2, the stock recently settled at EUR 1.80. Here, too, one could buy on weakness, but it is also important to note the high volatility and be aware that this is highly speculative. If successful, based on the chart pattern, a price target of EUR 2.50–2.70 beckons in a further potential upward wave.

Technological Challenge from HPQ Silicon

Moving away from the political arena and events in the UK, the path leads directly to Canada, where HPQ Silicon aims to strike fear into its competitors with strong performance data. On April 30, 2026, HPQ Silicon released a statement that garnered significant attention across the tech industry. Together with its partner Novacium, the company achieved a breakthrough in the field of drone batteries. In laboratory settings, a semi-solid battery pack equipped with their GEN4 silicon anode material reached a spectacular energy density of 395 watt-hours per kilogram. Weighing 1,160 grams, the system delivered a capacity of 15,900 milliampere-hours. This represents a performance increase of 23 to 36% over conventional lithium-polymer or NMC batteries, which typically cap out at 290 to 320 watt-hours per kilogram. The GEN4 material works independently of the battery's form factor and has already proven itself in classic 21700 cylindrical cells, yielding over 7,000 milliampere-hours. Furthermore, the semi-solid electrolyte mitigates the problematic volumetric expansion that silicon undergoes during charging. This all sounds highly promising; above all, its potential application in drones gives the company a distinct defence-tech angle, which is likely not yet fully priced in by the market.

The Path to Production and Chart Outlook

However, strong lab results are only half the battle—not just on the stock market—which is why management shifted its focus toward commercial implementation on May 5, 2026. The company is currently navigating the pre-commercial production phase for standardized 18650 and 21700 cell formats. In addition, vital international safety certifications, including UL 1642 and UN 38.3, are pending; without these, the cells may neither be shipped globally nor deployed in commercial applications. HPQ is pursuing a strategically more sensible path of integration rather than reinvention. Its proprietary GEN3 and GEN4 materials can be integrated as a drop-in solution into existing lithium-ion battery production lines. Manufacturers do not need to invest billions in new machinery, which should significantly accelerate market launch. So far, this optimism has barely registered on the stock market, as the stock has not yet been discovered by the masses. This disconnect is evident in the chart: HPQ Silicon's stock has repeatedly tested a support level around CAD 0.16 in recent months. Currently, the stock is trading within a range of CAD 0.16 to CAD 0.22—and has been for weeks. Only a sustained breakout above the CAD 0.24 hurdle will clear a path upward, at which point technical price targets in the CAD 0.30 zone will quickly come into focus.

Even after Weichai's exit, Ballard Power remains a highly volatile risk investment, where operational successes must first overcome the red ink. ITM Power, on the other hand, faces a critical period in late May, which could unlock significant short-term upside potential through government subsidies and index inclusion. Highly speculative investors might nevertheless consider buying on pullbacks, as the momentum remains upward. HPQ Silicon, meanwhile, stands out for its presented battery performance data and an interesting integration strategy for the mass market. The repeatedly tested support level at CAD 0.16 suggests a possible bottom formation in the chart. At current levels, HPQ Silicon appears to offer an interesting long-term opportunity, particularly if the stock manages to break above its key technical resistance level.
