Earnings in focus as European shares pause after Trump rally; Pearson dives

European shares ended little changed on Wednesday with investors looking at corporate earnings for market direction as more doubts emerged that a rally triggered by Donald Trump's US presidential election win would continue. The STOXX 600 edged 0.2 percent higher after a choppy session, while the UK's FTSE added 0.4 percent, bouncing after posting its biggest one-day drop since June 2016 in the previous session on Brexit jitters. France's CAC and Madrid's IBEX both ended down slightly.
The pan-European index has gained nearly 10 percent over the last two months but has come off from its early January peak on concerns Trump may not fully deliver on his stimulus promises.
