Nikkei 225 Down 0.2% as Chip Stocks, Trading Houses Weigh

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