** Shares in Accelleron ACLN.S jump around 13% to a new record high after the engines components maker increased its revenue guidance for 2025
** The Swiss firm, an ABB ABBN.S spin-off, expects constant currency revenue growth between 16%-19%, up from 4%-6%
** The positive update is not surprising, given Accelleron's performance in H1, Vontobel analysts say
** However, they add that the magnitude of the hike is "striking" and raises the question of whether the mid-term guidance for 2-4% sales growth has become outdated
