Frankfurt's DAX 40 was little changed around 25,585 on Wednesday, as traders continued to assess diplomatic efforts to end the Middle East conflict. Oil prices extended their slide amid growing signs that a potential agreement between the US and Iran could help end the war and facilitate the reopening of the Strait of Hormuz. Meanwhile, flash services PMI data for Germany surprised on the upside. SAP, MTU Aero Engines, Siemens and Rheinmetall were among the top performers, rising between 0.8%-2%. On the slip side, Daimler Truck, Scout24, Deutsche Telekom and Infineon Technologies faced heavy selling pressure.
