On Tuesday, Japan's Nikkei share average closed up by 0.89%, reaching 59,349.17, buoyed by optimism regarding potential peace talks between Iran and the United States in Pakistan. This optimism lifted the risk appetite among investors, particularly in the technology sector, with notable gains in chip-related stocks. Tokyo Electron and Advantest rose by 3.46% and 0.37%, respectively, while Kioxia Holdings surged 7.31% and SoftBank Group climbed 8.53%. However, Takamasa Ikeda, a senior portfolio manager at GCI Asset Management, cautioned that the market may be overly optimistic, highlighting concerns about potential supply chain disruptions that could arise as the ceasefire nears its end. Notably, Fujikura and Furukawa Electric, both key players in fiber optic cable production, saw their shares increase by 6.51% and 2.76% respectively. In contrast, banking stocks faced declines, with Mitsubishi UFJ Financial Group and Mizuho Financial Group falling by 1.39% and 1.89%. Of the more than 1,600 stocks traded on the Tokyo Stock Exchange's prime market, 32% saw gains, while 64% declined and 3% remained unchanged.
