On Monday, the ASX 200 index gained slightly, closing up 2.3 points to 8,233.50, driven by rallies in major miners and energy stocks amid anticipation of a US-China trade deal announcement. Key stocks included Woodside, Santos, and BHP, while healthcare stocks struggled, influenced by US President Trump’s plans to lower drug prices, affecting companies like CSL. As US futures soared on positive trade negotiation expectations, mixed responses were noted in Australia, with investors keenly awaiting tariff updates.
