European equities traded higher on Wednesday, shrugging off the weakness in Asian stocks. Markets in Europe are now fixed on the ECB meeting Thursday, where investors hope President Mario Draghi will take action, with a possible further cut in the deposit rate, which is already in negative territory, together with a further extension of the period and quantity of asset purchases.
"Mario Draghi's credibility will be seriously damaged if the ECB does not opt for further monetary easing this week. The last time he gave strong hints that action was imminent was ahead of December's meeting, when he was unable to persuade the ECB to go along with him," said Jeremy Beckwith, director of manager research at Morningstar UK.
Asian markets were mixed Wednesday, with China shares dropping, as analysts pointed to renewed investor concerns over the mainland's economy following lower-than-expected trade data for February.
