A number of other European companies also kept investors on their toes as they reported earnings on Tuesday. In the auto space, BMW reiterated its guidance for 2016 after reporting a rise in core profit, helped by sales of luxury cars. Despite this, shares ended over 2 percent down.
Autos in general under-performed most sectors, closing 2.7 percent down, with Volkswagen, Fiat and Porsche all off more than 4 percent each.
Meanwhile, German airline Lufthansa reported a nearly 12 percent year-on-year rise in earnings before interest and taxes (EBIT) for the first half of the year. The company warned, however, that the second-half of the year would be tougher with full-year adjusted EBIT for 2016 likely to come in below last year's level. Lufthansa said it will continue with cost-cutting measures. Shares slipped 3.2 percent.
InterContinental Hotels Group popped 3 percent after it reported a rise in first-half operating profit and said that it was confident in the outlook for the rest of the year. Direct Line was the STOXX 600's best performer, up 12.6 percent after it delivered half-yearly profits that beat forecasts.
