Japan's Nikkei 225 index soared to an all-time high of 52,411.34, marking a 2.1% increase, fueled by a robust rally in tech stocks and a depreciating yen. The Topix index also achieved a new peak, climbing 0.9% to 3,331.83, with October's gains hitting 16.6%, the strongest monthly performance since 1994. Semiconductor companies, including Socionext, saw significant gains, with Socionext shares rising nearly 17%. The yen's decline to record lows against the euro and dollar followed the Bank of Japan's decision to maintain its current interest rates.
