The pan-European Stoxx 600 was down around 0.1% during lunchtime trade, with most sectors and major bourses in negative territory. Market focus is also attuned to corporate earnings, with a string of U.S. companies releasing their first-quarter reports this week. European markets were marginally lower Wednesday afternoon, amid ongoing concerns about a global economic downturn.
