News: XIJ Australia shares end lower as vaccine doubts weigh

• Oil stocks record worst day in nearly a month
• ASX 200 still on track for best month ever

(Updates to close)

Australia shares ended lower on Friday as renewed doubts about a promising coronavirus vaccine dented investor sentiment, while Treasury Wine dived on China's plans to impose temporary anti-dumping measures on Australian wine imports.

The S&P/ASX 200 index (xjo) fell 0.5% to end the session at 6,601.1 points and close lower for the second straight day.

Global markets eased after several scientists questioned some efficacy results of a trial of UK drugmaker AstraZeneca's AZN.L COVID-19 vaccine candidate, stoking worries that this could lead to a delay in key approvals.

"It's likely the company will start a new trial to firm up results. The news was enough to trigger profit taking, given the importance of a vaccine to market confidence," said Michael McCarthy, chief market strategist at CMC Markets and Stockbroking.

Optimism around multiple potential effective coronavirus treatments have partly buoyed stock markets in November, with the Australian bourse on track for its best month ever on the back of a near 25% surge.

Treasury Wine Estates Ltd (TWE) plunged more than 14% and was the worst performer on the ASX 200 before trading in its shares was halted.

China said it will impose temporary anti-dumping tariffs on wine imported from Australia from Nov. 28, with Treasury Wine required to pay the highest deposit to China's customs authority of all wine importers.
