European shares unchanged amid doubts over COVID-19 vaccine

• Still, a boost from healthcare stocks helped the pan-European STOXX 600 shed early losses, and the index was last trading flat.
• Austrian Chancellor Sebastian Kurz said on Tuesday a group of EU states will propose funding the recovery efforts with loans, not grants.
• The world's biggest credit data company Experian Plc  gained 6.4pc as it said its executive directors would take a 25pc salary cut for six months.

European shares were flat on Wednesday after a downbeat session on Wall Street, as doubts over a potential COVID-19 vaccine fanned concerns about whether and how fast the world can successfully emerge from the coronavirus crisis.

Still, a boost from healthcare stocks helped the pan-European STOXX 600 shed early losses, and the index was last trading flat.

Wall Street fell more than 1pc overnight after a media report questioned the validity of the results of U.S. drugmaker Moderna's coronavirus vaccine trial that had sent stocks soaring on Monday.

A market recovery from March lows has stalled in May, as investors weigh the chance of a resurgence in coronavirus cases as many countries restart their economies after months-long lockdowns. The STOXX 600 is down 0.5pc this month after a 6pc jump in April.

"Investors are playing a waiting game," said Edmund Shing, global head of equity derivatives strategy at BNP Paribas. "The reason for that is we want to see how the exit from lockdowns proceed and see how quickly each economy picks up."

European markets have cheered a Franco-German proposal this week for a 500 billion-euro Recovery Fund that would bind all 27 European Union states to raise debt jointly to offer grants to regions hit hardest by the coronavirus pandemic.

However, Austrian Chancellor Sebastian Kurz said on Tuesday a group of EU states will propose funding the recovery efforts with loans, not grants.

A series of positive corporate updates limited losses in the markets.
