AP Photo/Richard Drew Fiat Chrysler shares dove more than 10% after company cut guidance on 2018 financial results. The auto giant said it expected net revenues of between €115 billion and €118 billion in 2018, down from the previous forecast of €125 billion. Shares were briefly halted because of the size of the drop. The announcement came on the same day as the death of former CEO Sergio Marchionne.
