The Australian stock market is weaker at noon after mixed leads from Wall Street on Friday on a better than forecast United States jobs report and worries over Ukraine-Russia tensions.
At 12.05pm (AEDT), he benchmark S&P/ASX200 index was 0.82 per cent lower at 5,417.7 points, while the broader All Ordinaries index fell 0.73 per cent to 5,437 points.
IG market strategist Stan Shamu said the lower open was "a no-brainer".
"There's just a raft of negative factors just weighing on sentiment to open up the week," he said.
"We had the China data showing a sharp drop in exports, we have the Ukraine situation starting to flare up again, with Russia continuing to increase its presence with more troops in Crimea."
In Australia, the market on Friday ended the week with a slight gain as investors remained unfazed by Russia's incursion into Ukraine and drew comfort from local economic data.
The benchmark S&P/ASX200 index was up 16.4 points, or 0.3 per cent, to 5,462.3 points.
The broader All Ordinaries index added 17.3 points, or 0.32 per cent, at 5,477 points.
