BYD Stock Plunges 36% While the Company Charges Into Grid Storage and Autonomous Driving Guarantees

Chinese EV giant BYD's shares tumble 36% in a year, yet it launches Americas' largest storage station, assumes full liability for self-driving mishaps, and presses European expansion amid geopolitical risks.

BYD presents a study in contradictions. Its shares are wallowing near a 52-week low of €9.21, having lost roughly 36% over the past twelve months and about 15% year to date — the exact figure depends on the trading day cited, with some reports putting the year-to-date decline at 14% and others at 16%. Yet behind the dismal stock price, the Chinese giant is rolling out one of the Americas’ largest battery storage stations, taking full legal responsibility for autonomous driving mishaps, and pressing ahead with European expansion. Investors, however, are demanding more than ambition: they want proof that growth can be profitable.

Megabatteries and Net-Zero Ambitions

While electric vehicles grab headlines, BYD’s energy storage business is quietly bulking up. Mid-June saw the commissioning of the Elena storage station in Chile’s Atacama Desert, a facility with a capacity of 3.5 gigawatt-hours — the largest single storage project on the American continent. Closer to home, the company partnered with Greenvolt Power to switch on a nearly 100-megawatt storage site in Buj, Hungary, using BYD’s MC-Cube technology to help stabilise Europe’s power grid.

These projects underpin a longer-term bet: BYD is developing sodium-ion batteries for stationary storage and aims to achieve extremely low costs by 2027. That timeline may seem distant, but the operational pipeline is already full.

Taking the Wheel on Liability

In China, BYD is trying to accelerate adoption of autonomous driving with an unusual guarantee. The company now assumes full liability for accidents caused by its “God’s Eye” urban assistance system, covering the first year after delivery or software update. After similar pledges, the usage rate for automatic parking features jumped from 21% to 93%. The technology relies on the new XUANJI A3 chip, a tiny processor capable of highly automated driving functions. Currently, over three million BYD vehicles equipped with such assistants are on Chinese roads.

Europe: Patience Required

On the international front, BYD’s plans are ambitious but slow-burning. Production at its new plant in Hungary is slated to start in the fourth quarter of 2026. A proposed facility in Turkey is paused, while the company explores potential sites in Spain. Local production brings execution risks and political sensitivities. The market is unlikely to reward the strategy until overseas profits visibly offset the pressure coming from China.

At home, the picture is more challenging. Domestic demand is soft, and rivals such as Leapmotor and Geely are waging an aggressive price war. Chinese authorities have stepped in to call for an end to the ruinous discounting — a step that confirms just how strained the industry’s economics have become. Size alone no longer guarantees pricing power.

Geopolitical Headwinds Mount

Political risks are adding to the gloom. In mid-June, the U.S. Department of Defense placed BYD on a blacklist, alleging ties to the Chinese military. Beijing’s commerce ministry hit back sharply. Meanwhile, the company is navigating trade talks with Canada, where officials are demanding local parts sourcing and strict data protection as conditions for market entry.

Finding New Investors in Unlikely Places

To broaden its shareholder base, BYD has taken an unusual route: the cryptocurrency exchange Gate.io now lists the stock, allowing crypto investors to buy in directly. That move may help diversify ownership, but it does little to address the core concerns that have hammered the share price.

The Bottom Line: Proof Over Promises

BYD’s market capitalisation still stands at roughly $120 billion — it is not a distressed company. But the market is treating it as a former darling under scrutiny. A dividend of 0.358 renminbi is due at the end of July 2026, yet that does little to shift the overall picture. The stock may be oversold — the relative strength index is 29.8 — and a short-term bounce is plausible. But oversold does not mean undervalued. Until BYD can show that its home market is stabilising and that its foreign expansion is delivering better margins, the sceptics are likely to stay in charge.
