Japan's Nikkei share average concluded trading on Tuesday with a 0.52% increase, reaching 62,742.57 after a volatile session. The broader Topix index also advanced, climbing 0.83% to 3,872.9. The uptick was fueled by investor interest in artificial intelligence-related stocks, particularly in the semiconductor sector. After an initial dip due to a decline in South Korea's equity benchmark, investors returned to buy chip-related shares. Noteworthy performers included Furukawa Electric, which surged 16% following its announcement of a stock split, and Ibiden, which rose 5.7% after upgrading its sales and profit forecasts. In contrast, Fast Retailing, the owner of Uniqlo, fell 3.77%, negatively impacting the Nikkei. Overall, of the more than 1,600 stocks on the Tokyo Stock Exchange's prime market, 42% advanced, while 53% declined, and 3% remained unchanged.
