European share markets slipped on Thursday following a threat from U.S. President Donald Trump to impose 25% tariffs on imports from the EU, but stocks globally held broadly steady after Nvidia's results threw up no big surprises.

European equity index futures are pointing to a weak start as investors parse the latest tariff announcements from US President Donald Trump and after earnings from Nvidia Corp. failed to impress.

Stocks opened higher Wednesday as investors looked ahead to AI bellwether Nvidia's ( NVDA) after-the-close earnings report. But the main indexes turned lower in afternoon trading when President Donald Trump said he is considering implementing 25% tariffs on the European Union.
