European stocks are expected to open higher on Wednesday, with the U.K. FTSE index expected to be 0.6% higher, Germany's DAX up 0.5%, France's CAC 40 up 0., and Italy's FTTE MIB 0.7% higher. The focus on earnings comes as Siemens unveils a $7 billion share buyback program for the next five years after posting a forecast-beating net profit of 2.03 billion euros for the first quarter. The news comes after European stocks traded in negative territory due to concerns about the resolution of the U.,S.-Iran war and potential leadership challenges for UK Prime Minister Keir Starmer.
