AUSTRALIAN stocks regained their momentum after stumbling at the start of the week, to close near a 22-month high.

The strong finish came as investors welcomed news that China had recorded better-than-expected trade data, fuelling optimism that its growth may be rebounding from its recent slowdown.

The benchmark S&P/ASX 200 Index gained 50.3 points, or 1 per cent, at 4971.3 points for the week, while the broader All Ordinaries Index rose 47.5 points, or 1 per cent, at 4989.4 points.

The Reserve Bank decided to keep the official cash rate on hold this week, at 3 per cent. But it said in a statement accompanying the decision that it had scope to cut rates if necessary. Then the RBA's statement on monetary policy, released on Friday, showed that it had lowered expectations for economic growth, and that it had revised up its outlook for unemployment growth.

The statement - which opened the door for interest rate cuts - saw the Australian dollar fall to its lowest level in more than three months.

On Friday the currency slipped to US102.56¢ briefly, its weakest level since October 24, before recovering to close on US102.98¢.

Economists said the statement - which highlighted subdued inflation, a weak employment outlook and expectations of below trend growth - suggested that another rate cut was on the cards.

''The RBA has hinted it is open to another easing,'' St George economist Janu Chan said. ''If the run of data disappoints from now then there is a risk that the RBA will cut in March.''

News Corporation rose 13¢, at $27.43, even as the future of its Australian newspapers looked more uncertain and were partly blamed for an earnings downgrade.
