Frankfurt’s DAX 40 closed marginally up at 24,933 on Monday, as investors were reluctant to take strong positions ahead of the Fed's monetary policy decision and a busy corporate earnings calendar. At the same time, broader geopolitical risks persisted despite recent concerns surrounding US President Trump's stance on Greenland and the risk of a transatlantic trade dispute appear to have subsided. On the data front, German business sentiment remained unchanged in January, with the Ifo business climate index steady at 87.6, contrary to analysts' expectations of a rise. Among key movers, Bayer and GEA Group were the top performers, adding 4.3% and 3.6%, respectively. Adidas gained 2.3%, tracking a sharp rebound in Puma's shares, fueled by persistent takeover speculation. SAP rose 1.8% ahead of its Q4 results due Thursday. Banks were also in demand, with Commerzbank up 1.2% and Deutsche Bank up 1%. However, the aerospace and defence sector and auto stocks faced the greatest pressure.
