The Australian share market has opened lower, with the big banks and major mining and energy stocks down following a weak lead from Wall Street and lower prices for copper and oil.
Phillip Capital senior client adviser Michael Heffernan said there was no news to drive the local bourse upward.
"The banks are getting knocked around today - they're continuing on their very weak performance over the last year," Mr Heffernan said.
"Overseas markets weren't too bad. There's nothing really majorly negative on the scene, but there's no good news from the banks.
"You've got nothing to push the market solidly in an upward direction at the moment."
Investors are awaiting trade data for February and the Reserve Bank of Australia's decision on interest rates later on Tuesday - the RBA board is expected to keep rates on hold.
