Nikkei Falls 0.2% as Chip Stocks and Trading Houses Drag

Japan's Nikkei 225 fell 0.2% on Sept. 15, 2026, dragged by chip-related stocks and trading houses, according to Wall Street Journal market coverage published Sept. 15, 2026. For savers in index funds, that means a few big tech names can pull the whole benchmark down even when most stocks hold up. I see this as narrow weakness, not broad selling.
