Japan's Nikkei share average took a leap of over two percent on Monday, propelled by robust performance in chip-related stocks reflecting U.S. semiconductor advances. Investors demonstrated a healthier risk appetite, encouraged by steady bond yields and a firm yen. Both Advantest and Tokyo Electron saw an uptick of more than four percent, while Kokusai Electric impressively skyrocketed eight percent due to its new status in the Nikkei 225 index.
