The Australian sharemarket is trading lower after investors felt some disappointment over the latest moves by the US central bank to boost the US economy.
The US Federal Reserve has extended a program that aims to encourage borrowing and spending by reducing long-term interest rates as it cut its forecast for US growth.
But the Fed has said it was prepared to take more action if needed.

OptionsXpress market analyst Ben Le Brun said investors were trying to make up their minds on what the latest Federal Reserve stimulus package meant for the US.
"There might be some slightly disappointed investors and traders as well," Mr Le Brun said.
Mr Le Brun noted that the Federal Reserve had said that it stood ready to do more should economic conditions warrant it.
"US markets are only four per cent off their 2012 highs at the moment, so that in itself tells you that conditions aren't quite right for a full-blown package," Mr Le Brun said.
