Frankfurt's DAX index experienced a significant uptick, climbing approximately 1.3% to conclude at 24,438.6 on Thursday. This marks its highest point since July 10 and reflects a five-day streak of gains. The boost in investor sentiment was largely driven by a global surge in optimism surrounding artificial intelligence, which helped offset anxieties about the ongoing US government shutdown, now in its second day. In corporate news, Siemens stood out with a 4.2% increase, fueled by reports that the German conglomerate is exploring a potential spin-off of a substantial part of its stake in Siemens Healthineers. Siemens Energy also saw notable gains, rising 4.1%, particularly after Berenberg increased its price target from €75.00 to €122.00, while reaffirming its buy recommendation. Additionally, tech sector leaders such as Infineon Technologies, which rose by 2%, and SAP, up by 1.9%, posted solid gains in the wake of an OpenAI share sale, which has positioned the firm as the world’s most valuable startup.
