The share market is more than one per cent weaker as investors worry about sluggish global growth and the Ebola crisis in west Africa.

All sectors are suffering losses as Asian share markets follow the downward trajectory of US and European markets.

Weaker commodity prices, apart from gold, are kicking the mining-related materials sector.

Bargain hunters are also absent, OptionsXpress analyst Ben Le Brun says.

“We’ve got all sectors of the market trending significantly lower this morning,” he said.

“It’s a really lethal cocktail when you get the materials space and the banks all trading lower.

“Ebola was on investor and trader lips last night; global growth has been a continuing concern.”
