Investing.com -- European stock markets opened mostly lower, overshadowed by the collapse of U.K. travel group Thomas Cook and another rise in oil prices due to lingering geopolitical concerns.
Travel groups in focus included German-listed Tui (DE:TUIGn), which rose 7.2% on the prospect of higher margins due to less competition. EasyJet (LON:EZJ) rose 4.9% while Ryanair (LON:RYA) rose 3.9% on similar perceptions, while U.K.-based online travel agent On The Beach Group (LON:OTB) rose 1.2% after saying it would take an unspecified hit to profits in the current fiscal year from Thomas Cook’s collapse. It had already fallen by a quarter in August.
