Japan's Main Stocks Slip 0.2% as Chip Firms Drag

Japan's stock index, the Nikkei 225, fell 0.2% on Sept. 15, 2026, pulled down by chip-makers and trading firms, according to Wall Street Journal market coverage published Sept. 15, 2026. For savers in index funds that track the market, a few tech firms can sink the average even if most stocks hold steady. I see narrow weakness, not broad selling.
