THE share market closed sharply lower, reversing earlier gains on the day, as investors worried over the federal budget and the cost of the trillion dollar bailout of the debt-laden euro zone economies.
By 16:15 (AEST)the benchmark S&P/ASX200 index had fallen 51.8 points, or 1.13 per cent, to 4548 points, while the broader All Ordinaries index was 49 points, or 1.06 per cent, down at 4573.2 points.
On the Sydney Futures Exchange, the June share price index futures contract was 58 points lower at 4552 points, on volume of 44,627 contracts.
City Index market strategist Michael McCarthy said the local market started on a positive footing and then dropped heavily from 11:30 on very good trading volume.
"We're susceptible, given the events over the last week, to fear,'' he said.
"In the absence of further positive stimulus, we will tend to see selling dominate until markets settle down again.''
