All Ords slips back under 5000 mark

"We've had considerable volatility across equity markets brought about by the increased volatility in recent weeks of commodity prices and today we're seeing the fallout of that volatility," Mr Spiteri said.
"The gold price took a big fall on Friday evening and subsequently in Asian trading here."
