BYD's European Reset Overshadows Battery Gains as Stock Plunges Toward Year Low

Despite 16.56% battery market share and strong sector growth, BYD's stock near 52-week low as vehicle sales flat, European factory plans stall, and technicals show oversold conditions.

BYD's grip on China's battery market remains firm, but operational setbacks from vehicle sales to European factory plans are weighing heavily on the stock. The Shenzhen-based automaker holds second place in the country's fast-growing battery sector, yet the share price has slumped to within a whisker of its 52-week trough, reflecting investor unease about the group's broader trajectory.

China's Automotive Battery Innovation Alliance reported May 2026 installations of traction batteries at 71.9 GWh, a 25.9% jump year-on-year. CATL leads with 33.08 GWh and a 46.14% market share, while BYD carved out 11.87 GWh, good for 16.56%. Combined production of traction and storage batteries surged to 191.7 GWh, up 55.2% from the prior year, with sales reaching 182.2 GWh. Those top-line figures underline the sector's momentum, but BYD's own vehicle sales tell a more cautious story.

In May, the manufacturer sold 383,453 new-energy vehicles — barely above the 382,476 registered a year earlier. The cumulative tally from January to May stands at 1.405 million units, roughly 20% below the comparable period in 2025. Exports remained a bright spot at 160,644 units in May alone, and China's broader NEV penetration hit 56.9% of the new-car market. Yet the home-market sales gap has yet to narrow.

That discrepancy is feeding into stock weakness. BYD's H-share went ex-dividend on 11 June, with a final payout of 0.358 renminbi per share for fiscal 2025, payable on 31 July. The stock now trades at €9.51, just 2.8% above its 52-week low of €9.25 — a level touched the previous day. Over 30 days the shares have shed 14%, and over 12 months almost 37%. The 50-day moving average of €10.85 and the 200-day average of €10.99 sit well above the current price. The relative strength index at 33.7 signals oversold conditions, but technical analysts warn that alone does not herald a reversal.

Meanwhile, BYD's European ambitions have hit a critical juncture. The company has indefinitely shelved its planned €1 billion factory in Turkey after the government withdrew tax exemptions and demanded that promised investments be implemented. Vice-President Stella Li confirmed the pause, noting that the site in Manisa province, intended to produce 150,000 vehicles annually, has seen almost no construction activity. Local sales collapsed to just 152 cars in May, a dramatic drop from earlier targets.

Instead, BYD is accelerating its first dedicated European passenger-car plant in Szeged, Hungary, where production is slated to start by end of 2026. The group is also shifting its expansion strategy: rather than building from scratch, it now plans to acquire existing European factories. A second site in southern Europe, possibly Spain, is under review, partly to circumvent fresh EU tariffs on Chinese-made electric vehicles. In a parallel push, BYD is pouring over €2 billion into a European charging network, aiming for 3,000 ultra-fast stations by year-end that can replenish a battery in roughly five minutes.

Yet not everything is proceeding smoothly on the technology front. Chairman Wang Chuanfu warned at the annual general meeting that the second generation of the Blade battery is encountering technical problems, preventing mass production. The bottleneck threatens to constrain global growth at a time when the company is banking on its battery prowess to differentiate itself.

For now, the market appears to be pricing in the operational friction. The RSI reading — 35 points in recent sessions — confirms bearish sentiment. On a monthly basis, the stock has lost around 13%. Until BYD's monthly sales reports show a convincing return to growth, the battery data alone will struggle to arrest the slide. The coming months, especially the ramp-up of the Hungary plant, will be decisive in testing whether the European reset can translate into a share-price recovery.
