Australia’s mining sector has reversed its long-standing dominance on the ASX, falling from the best-performing group over the past year to the worst in the last 30 days.

Australian equity futures recently erased early gains after US President Donald Trump threatened military action against Iran, coinciding with Tehran’s announcement that it was closing the Strait of Hormuz.

At the same time, capital is flowing out of traditional resource plays and into technology stocks driven by AI optimism.
