BYD Overtakes Tesla in Europe, Unveils New Models, but Stock Slumps to Fresh 52-Week Low

BYD's European EV registrations surge past Tesla in May, yet stock plummets to 52-week low of EUR 8.08, down 25% YTD, as investors worry about margins and China price war.

The disconnect between BYD’s operational momentum and its sinking share price has rarely been starker. While the Chinese automaker’s European registrations surged past Tesla in May and its legal team scored multiple victories against online detractors, the stock has tumbled to a fresh 52-week low — shedding nearly a quarter of its value since January.

BYD posted 32,380 new registrations across the EU, EFTA and the UK in May, according to industry data — a 137% jump from the same month last year that lifted its regional market share from 1.2% to 2.8%. That tally comfortably beat Tesla’s 28,610 registrations in the same territory. Over the first five months of 2026, BYD’s cumulative lead in the region reached 135,307 units versus Tesla’s 118,068. The broader European backdrop is also turning more electric: pure battery-electric vehicles now account for 20% of the EU market, up from 15.3% a year earlier.

Yet the share price tells a different story. BYD closed its most recent trading session at EUR 8.18, down 4.17% on the day, after touching an intraday low of EUR 8.08 — a new 52-week trough. The paper has lost roughly 18% over the past 30 days alone, and year-to-date deficits have widened to around 25%. The 50-day moving average now sits more than 20% above the current price, while the Relative Strength Index has plunged to 19.6 from 23 a week earlier, flagging deeply oversold conditions.

Management is not standing still. The automaker’s legal department recently won a string of defamation cases against social-media accounts accused of spreading false information about the brand. Courts imposed fines ranging from 313,800 yuan to 2.01 million yuan on five separate accounts. PR chief Li Yunfei has vowed to intensify the crackdown, offering rewards of up to 5 million yuan for tips about organised smear campaigns. Operationally, the company is also pressing ahead with new launches. At the Busan Mobility Show in South Korea, BYD debuted the Sea Lion 6 plug-in hybrid SUV, priced at roughly 37.5 million won and offering 70 kilometres of electric range with a 30-minute fast-charge capability. Next week brings the Linghui M9 van for business customers and ride-hailing fleets (June 29), followed on July 2 by the flagship Seal 07 sedan, which rides on an 800-volt architecture and promises over 1,000 kilometres of range in its pure-electric version.

Despite these tailwinds, investors remain sceptical. The problem, analysts note, is that strong European registration numbers do not automatically translate into healthy margins. Outside China, BYD faces hefty costs for logistics, dealer networks and marketing, while at home an intense price war continues to compress profitability. The market wants tangible evidence that Europe’s growth is feeding through to the bottom line, something only the next quarterly earnings report can provide.

For now, the technical picture is precarious. The 200-day moving average sits at EUR 10.86, the 50-day at EUR 10.35 — both far above the current price and sloping downward. If the EUR 8.08 support level gives way, chart watchers warn of further declines. With new model launches and a European market share that now surpasses Tesla’s, BYD has the narrative pieces for a rebound. The stock just needs the numbers to prove it can make money as well as it can sell cars.
