European stocks edged higher on Tuesday, with the STOXX 50 rising 0.5% and the STOXX 600 Index gaining 0.1%. The rebound followed a weaker session the previous day, as investors attempted to look past escalating tensions in the Middle East and refocus on the ongoing earnings season. Rheinmetall advanced 1.7% after reporting a 7.7% increase in earnings, while UniCredit jumped 3.2% on the back of stronger net profit and revenue. In contrast, HSBC dropped more than 5% after missing pre-tax profit expectations, weighed down by higher projected credit losses and a fraud case in the UK. Banco de Sabadell also declined, falling 2.7% after reporting a drop in profit. Elsewhere, ASML Holding rose 0.7%, and Novo Nordisk gained 1.1%.
