The S&P/ASX 200 finished 0.5% higher to a new record at 9,175 on Thursday, briefly testing the 9,200 level earlier in the session, lifted by gains in heavyweight miners, healthcare leaders, and technology stocks amid a strong earnings season. Miners extended their rally, climbing 1.2% to close at a fresh peak, supported by continued earnings momentum and steady fund rotation into the sector. Heavyweight BHP rose 2.2% to a record close, while Rio Tinto advanced 3.7%. Firmer copper prices, driven by a post-Lunar New Year pickup in Chinese import demand, added further support. Healthcare stocks also gained 1.6%, led by Ramsay Health Care, which jumped 10.4% after beating first-half profit expectations, while Telix Pharmaceuticals surged 10.9%. Technology shares soared 5.2%, tracking a global rally after blockbuster results from Nvidia helped ease concerns over AI-related risks. Conversely, energy and gold stocks mostly weighed in the index, while financials ended little changed.
