• The STOXX Europe 600 Technology Index (.SX8P) dropped as much as 4% intraday, potentially marking its largest one-day decline since April 2025, before partially recovering.
  • The selloff was driven by renewed trade uncertainty after President Trump threatened tariffs on European exports, rattling export-heavy economies like Germany and France.
  • Individual tech stocks showed mixed performance, with Nokia, Ericsson (ERIC), and STMicroelectronics (STM) declining while SAP (SAP) and Infineon posted gains, highlighting sector volatility.

European tech stocks faced a sharp selloff on Thursday, with the STOXX Europe 600 Technology Index (.SX8P) plummeting as much as 4% in early trading—its steepest intraday drop in months. The index later pared some losses but remained down significantly, dragging the broader STOXX 600 lower by 0.2% and marking the biggest daily decline for the tech sector since April 2025, according to market data. The move came amid thin U.S. holiday trading volumes, which may have exaggerated the swing, people familiar with the matter noted.

Efforts to stabilize the sector hit a snag as broader market pressures intensified. The selloff was primarily triggered by President Trump's announcement of planned tariffs on European exports, starting at 10% on February 1, 2026, and rising to 25% by June 1 unless a deal over Greenland is reached. The tariffs would target goods from Denmark, Norway, Sweden, France, Germany, the Netherlands, Finland, and Britain, reintroducing trade uncertainty that has weighed on export-heavy economies. German and French stocks fell over 1.3%, with tech shares alongside luxury and auto sectors—down 3% and 2.2%, respectively—bearing the brunt. Euro zone volatility spiked to November highs as a result, analysts observed.

Without a swift resolution, the tech sector could face prolonged downside pressure. Individual movers included Nokia, which dropped 1.98% to 4.655, Ericsson, down 1.41% to 82.38, and STMicroelectronics, falling 0.87% to 22.345. In contrast, gainers like SAP, up 0.88% to 264.75, and Infineon, rising 0.22% to 34.77, provided limited offsets. The index, which has fluctuated between 768.90 and 851.47 recently, saw its sharp drop align with historical volatility spikes, such as those in January 2026 and April 2025 when similar Trump tariff rhetoric roiled markets. A trader at a European investment bank, who requested anonymity due to lack of authorization, described the move as "a knee-jerk reaction to geopolitical risks, but fundamentals remain shaky."

Discussions at the World Economic Forum in Davos are under scrutiny for potential trade cues, with EU officials urging caution to avoid escalation, per analysts at Capital Economics. The tariff threat echoes actions from April 2025, when global tariffs were imposed, and comes as German firms' U.S. investments have halved during Trump's second term due to prior trade tensions. In a brief statement, an EU spokesperson said they are "monitoring developments closely," though attempts to reach Trump administration officials for comment were unsuccessful. Meanwhile, some investors see a silver lining: the index had posted year-to-date gains of 4.06% as of late January, suggesting a possible rebound if tariff fears ease. Short-term, analysts doubt full implementation and expect EU restraint, but long-term, Capital.com warns of sustained volatility after a low-volatility start to 2026, potentially impacting tech manufacturing and trade-dependent jobs.

In related developments, six European semiconductor stocks rose on news of a U.S.-China tariff deal, contrasting the broad selloff, while the STOXX 600 had recently brushed aside some tariff fears to hit near four-month highs. Outliers like Beazley (BEZ.L), up 43% on a buyout offer, and Bayer (BAYN.DE), gaining 7.1% on positive court news, bucked the negative trend. As the situation evolves, market participants are eyeing filing deadlines and potential financial agreements to gauge resilience, with one fund manager quipping, "It's a bumpy ride, but tech always finds a way."
