KEY POINTS:
MELBOURNE - The Australian share market closed lower today despite a positive lead from US markets and the United States central bank's rescue of global insurer American International Group (AIG).
At the 1615 AEST close, the benchmark S&P/ASX200 index had fallen 28.6 points, or 0.6 per cent, to
4722.2, while the broader All Ordinaries index was down 30.1 points, or 0.63 per cent, to 4769.7.
The September share price index futures contract was 17 points lower at 4732, on a volume of 66,448 contracts, according to preliminary calculations.
ABN Amro Morgans private client adviser Trent Muller said the local market started positively today but turned south in the afternoon, led by futures trading.
"There's a bit of nervousness about how the US market will treat the AIG rescue. AIG is a Dow (Dow Jones Industrial Average index) component," Mr Muller said.
"It will most certainly be down tonight as a result of the dilution of shareholders' equity and that will potentially offset some upside on other financials."
He said investors were also asking themselves which company would be next to find itself in trouble.
"Most people are still very defensive in their investment policies these days, and they're waiting for a clear sign that we're reaching the bottom."
The US Federal Reserve today announced it would provide AIG with an US$85 billion (A$107.08 billion) rescue loan to save it from bankruptcy amid fears of a catastrophic meltdown of financial markets.
Global markets have been in turmoil this week, following US investment bank Lehman Brothers filing for bankruptcy, the fire sale of rival Merrill Lynch and concerns over the financial viability of AIG.
Australia's big insurers said today they had no or minimal exposure to AIG.
QBE Insurance Group added 89 cents to $24.12, AXA Asia Pacific firmed three cents to $5.15, Insurance Australia Group strengthened seven cents to $4.16, and Suncorp-Metway dipped 29 cents to $8.86.
