European stocks fell on Tuesday, with the "Stoxx 600" index down 0.2%, and shares of "SPB" dropping 7.7%. Losses were tempered by a 4.9% rise in shares of "Banco BPM" after Italy's third-largest bank raised its profit targets for this year and next, following stronger-than-expected profits in the first quarter. Additionally, shares of "Fresenius Medical Care" rose 1.4% after the German healthcare company reported a smaller-than-expected decline in adjusted operating income in the first quarter.
