European shares were mixed on Thursday, with banks on the back foot following a recent rally while commodity stocks were boosted as Brent crude oil prices hit $50 a barrel for the first time since November. The STOXX Europe 600 was down 0.1 percent at 348.06, with the FTSEurofirst 300 flat. Both indexes hit a 4 week high in the previous session. Britain's FTSE 100, France's CAC and Germany's DAX were all 0.1 percent higher. Banks fell 1.3 percent after a strong rally on Wednesday, led down by Banco Popular which slumped 25 percent after it announced a rights issue plan. Other Spanish banks Caixabank and Banco de Sabadell fell 3.4 percent and 4.5 percent respectively. However, oil companies rose 0.6 percent after Brent crude hit $50 dollars a barrel, boosted by a drawdown in crude stocks in the United States last week. Source: Reuters
