European stocks extended their slide as investors reacted to political unrest in France. The broader market move showed that concern about political stability was affecting sentiment across the region. Trading was not uniformly negative, however, because Ireland's Iseq edged higher. Ryanair shares rose 2.6%, moving against the broader direction of European trading. The airline's gain did not reverse the decline recorded across most European equities. The report gave no details about the unrest or the size of the losses on major indexes. Investors were left with a mixed market in which French political concerns contrasted with gains in individual stocks.
