The DAX 40 fell about 1.3% to close at 25,489 on Tuesday, ending a five-session winning streak and lagging behind other major European indices, as tech-sector nerves and renewed tensions in the Strait of Hormuz weighed on sentiment.

Semiconductor stocks came under marked pressure after Samsung’s outlook stirred fresh doubts about the durability of the AI-driven boom, overshadowing a sharp increase in its operating profit. Infineon Technologies dropped 8.3%, while Siemens Energy sank 8.6% following a downgrade from Barclays, amid growing concern that its share price had already discounted an unsustainably strong long-term upcycle.

Shares of companies exposed to data-center investment also retreated, with Hochtief down 5.3% and Siemens off 4.1%. Among other notable decliners, Airbus, Rheinmetall and MTU Aero Engines each lost more than 2%.

On the positive side, Beiersdorf and SAP both advanced 3.4%, while Fresenius Medical Care gained 2.7%, topping the list of DAX gainers.
