The news was gloomy from Wall Street where the Dow Jones Industrial Average was dragged 0.5% lower after rating agency Fitch downgraded the sovereign credit rating for Portugal, while US new home sales in February dropped to a record low for the second consecutive month.
"In light of weaker commodity prices, concern about Portugal's credit rating and European sovereign debt generally, and disappointing US economic data, equities have been fairly resilient," Dow Jones Newswires quoted Macquarie Private Wealth associate director Marcus Droga as saying.
“But I expect some further weakness across the board because the downgrade of Portugal highlights the fact that European sovereign debt problems haven't been resolved and could possibly be systemic.”
