Nikkei 225 — daily market movers
Macro backdrop
The Nikkei 225 fell about 0.94%, giving back ground after a strong prior session. Hotter-than-expected Tokyo CPI (as government subsidies unwound) and an unexpected uptick in the unemployment rate revived expectations for a Bank of Japan rate hike, pressuring rate-sensitive sectors. The index leaned risk-off, but beneath it dispersion was sharp as money rotated hard within the AI theme.

Common Themes
The gainers are overwhelmingly the AI-infrastructure 'shovel sellers': electric wire/optical-fiber makers (Furukawa, Fujikura, Sumitomo Electric), semiconductor materials and wafers (Resonac, SUMCO, Mitsui Mining & Smelting) and chip-test/power semis (Advantest, ROHM), rounded out by IT/DX services (Baycurrent, SHIFT). Most had no standalone same-day catalyst; instead money kept concentrating in the data-center and electrification supply chain, tracking the global AI capex boom.

Common Themes
Three threads run through the losers: SoftBank, the index heavyweight, gave back ground after completing its $30bn OpenAI program amid surging CDS and leverage worries; rate-sensitive financials and real estate (Credit Saison, Mitsui Fudosan, Sumitomo Realty, Daiwa Securities, Aozora Bank) were hit by revived BOJ-hike expectations; and autos (Nissan, Mazda, Mitsubishi Motors) plus defensive/healthcare names (Terumo, Shiseido, Konica Minolta, Nikon) weakened. Tokyo Electron's drop looks like profit-taking after the prior chip rally. Most names lacked a standalone catalyst — the moves are largely rotation.
Overall read
Despite the modest index decline, money rotated cleanly within the AI theme — out of SoftBank, the mega-cap AI proxy, and into the more physical AI-infrastructure supply chain (cables, wafers, chip materials) — while revived BOJ-hike expectations pushed investors out of financials, real estate and autos.
