The DAX 40 closed about 1.3% lower at 25,489 on Tuesday, snapping a five-day advance and underperforming its European peers, as investors weighed tech jitters and fresh hostilities in the Strait of Hormuz. Chip stocks came under heavy pressure after Samsung’s outlook sparked AI jitters, overshadowing a strong jump in operating profit. Infineon Technologies plunged 8.3%, while Siemens Energy slid 8.6% after a Barclays downgrade, as concerns grew that the stock had priced in an unsustainably strong long-term boom. Companies benefiting from data centers, such as Hochtief (-5.3%) and Siemens (-4.1%) also fell. Other top losers included Airbus, Rheinmetall and MTU Aero Engines, each falling more than 2%.
