European stocks erased the slight gains in morning trading to close in the red on Friday as investors monitored corporate developments and signs of progress in trade negotiations between the US and the European Union. The Eurozone's STOXX 50 fell 0.3% to close at 5,359 and the pan-European STOXX inched below the flatline to close at 547. Tech companies extended their volatile momentum as tariffs and broader economic uncertainty continued to cloud their outlook, with ASML dropping 2.6%. Heavyweight luxury brands and auto producers also closed down, with Hermes, LVMH, Mercedes Benz, and Stellantis losing between 1% and 3%. In turn, Vivendi soared 13.2% after a French financial market advisor concluded that a mandatory takeover bid for Vivendi by Bollore is required. Also, Saab soared 16% after the company reported stronger-than-expected second operating income. Over the week, both the STOXX 50 and STOXX 600 edged lower.
