Macro backdrop today

Today, investors look at the ongoing influence of elevated oil prices and firm bond yields on European equities, a combination that weighed on shares in the last session, according to a market wrap by Morningstar. For Alstom, higher financing costs and shifting expectations around central-bank policy remain relevant, as decisions by major central banks and movements in benchmark yields can affect capital-intensive transport and infrastructure projects. In addition, broader direction in the CAC index and European peers today may continue to frame trading in Alstom ahead of the open, with market participants watching whether the recent pullback in French equities stabilizes or extends.
