On Tuesday, the Australian stock market closed largely flat, with the S&P/ASX 200 index easing by 3.9 points to finish at 8,949.40 points. Investor sentiment was subdued as uncertainty loomed over U.S.-Iran peace talks, particularly as a ceasefire nears its end. Reports indicated that Iran is contemplating participation in talks with the U.S. in Pakistan, but no final decision has been made. Iranian Foreign Minister Abbas Araqchi highlighted ongoing U.S. ceasefire violations as a significant hurdle in the diplomatic process. In the mining sector, Rio Tinto saw its shares increase by 0.8% after reporting higher first-quarter output, while BHP shares fell by 0.3%. The energy sub-index declined by 0.9% due to falling oil prices linked to the peace talk expectations. Financial stocks also saw slight declines, with Commonwealth Bank of Australia and ANZ dropping 0.3% and 1.7%, respectively. Meanwhile, tech stocks have rebounded by 15% in April after suffering a 28% loss in the previous quarter, indicating a potential shift in investor focus.
