Weak performances from major banks, gold stocks and mega miners have dragged the bourse lower despite hopes of de-escalation in the Middle East boosting the Australian dollar to four-year highs.
The S&P/ASX200 fell 23.7 points on Thursday, down 0.26 per cent, to 8,955 as the broader All Ordinaries lost 7.5 points, or 0.08 per cent, to 9,173.6.
The top 200 was unable to hold above 9000 points for a third straight session despite global equities rallying on hopes the US and Iran are keen to resolve their conflict and ease its resulting energy shock.
Multiple Wall Street indices hit fresh records overnight, and benchmark indices in Japan, South Korea and Hong Kong were up between 1.5 per cent and two per cent at the time of writing, but a rotation out of Australia's blue-chip banks and miners held its exchange back.
"They're top-ranked banks in terms of credit exposures, they pay strong dividend yields, they have tax benefits and they're exposed to a domestic audience that's largely insulated from the globe, so seen as a great defensive asset but now that dynamic's reversing," Moomoo market strategist Michael McCarthy told AAP.
"The market has taken the view that we're just about done in the Middle East and everything's improving, so those defensive assets that they bought during that period are now being sold."
The heavyweight financials sector tumbled 1.3 per cent as NAB and CommBank fell more than 2.5 per cent each, carving out spots in the ASX200's top-10 worst performances for the day.
Raw materials slipped 0.4 per cent with a sluggish lead from BHP and Rio Tinto, but gold miners really dragged on the segment as the All Ordinaries gold sub-industry slipped 1.8 per cent.
The slump came despite the precious metal improving to $US4,818 ($A6,710) an ounce during the session.
Oil prices and ASX-listed energy stocks continued to cool off from their Persian Gulf conflict rallies, with most fossil fuel producers selling off.
Uranium stocks bucked the trend, with Paladin, Deep Yellow and Silex each up two per cent or more.
Viva Energy went into a trading halt after a fire at its Geelong fuel refinery, which intensified existing concerns about national fuel supply.
Virgin Australia is up more than 12 per cent in two sessions as investors bet on an easing of disruptions to Middle East airspace and a more modest outlook for jet fuel prices.
Qantas, which doesn't fly direct services to the region, has gained 1.7 per cent in the same period.
ASX-listed tech stocks continued their rebound, up more than seven per cent on Thursday, making it a 13.6 per cent charge in three sessions for the beaten-down segment.
Consumer discretionary stocks also benefited from a broader lift in sentiment, up 0.8 per cent despite a lumbering performance by Bunnings' owner Wesfarmers, tracking with the broader blue chip sell-off.
The brighter global growth outlook and a fading greenback helped send the Australian dollar to a four-year high of 71.98 US cents, before easing to 71.88 US cents, up from 71.38 US cents at 5pm on Wednesday.
