The stock market has gained 0.9% for the week, with energy shares rising and basic materials falling. Reports indicate that the market's weekly gain was also driven by factors such as a potential peace deal and a resurgence in AI-related trades, led by companies like Oracle and Nvidia. However, the exact reasons for the market's performance are somewhat unclear, with various outlets citing different factors, including oil prices, copper prices, and the impact of a US-Iran ceasefire.
