The Australian sharemarket extended its record-breaking run on Thursday as technology stocks continued to rebound from weeks of heavy selling.

The S&P/ASX 200 Index was up 56.80 points, or by 0.6 per cent, to 9185.10 at 12pm AEDT, after hitting a fresh intraday high of 9202.90. It comes after the benchmark’s record close of 9128.30 on Wednesday.

Technology was the strongest sector, buoyed by a blockbuster result from Nvidia after the close of trading, with the chip giant reporting record revenue for the fourth quarter. Locally, WiseTech Global jumped 5.2 per cent, Xero 7.6 per cent and NextDC 2.1 per cent.

Healthcare also bolstered sentiment. Sigma Healthcare rallied 6.5 per cent as same-store sales since January have increased 16.6 per cent. Ramsay Health Care surged 10.9 per cent as its underlying profit of $172 million was well ahead of expectations.

BHP took total gains this week past 8 per cent as it climbed 2.6 per cent and reached a record high. Rio Tinto firmed 3.7 per cent as copper prices rose by more than 1 per cent. BlueScope Steel lost 3.8 per cent as it rejected the $14.2 billion takeover proposal from SGH and Steel Dynamics, saying the offer was still too low.

Industrials were lower as Qantas dived 5.3 per cent to a two-month low on concerns about demand after its interim dividend and profit missed expectations.

“Demand is where things start to look a little worrying for shareholders. Qantas has wound back planned domestic capacity growth after softer-than-expected corporate demand, which is worth watching closely because corporate travel has historically been higher-margin and a reliable barometer of broader economic confidence,” eToro market analyst Josh Gilbert said.
