Nikkei 225 — daily market movers
Macro backdrop
The Nikkei 225 rose about 1.94% in a broad risk-on session. Gains were concentrated in AI-infrastructure names — silicon wafers, semiconductor materials and data-center cabling — and in megabanks, while defensive and domestic-demand names lagged.

Common Themes
The rally was overwhelmingly an AI-infrastructure story. The three big electric-wire makers — Sumitomo Electric (+6.7%), Fujikura (+5.9%) and Furukawa Electric (+4.7%) — moved together on data-center cable and optical-fiber demand, while silicon-wafer maker SUMCO (+9.1%) and semiconductor-materials group Resonac (+7.7%) led the 'shovel-sellers' supplying the AI build-out. SoftBank Group (+6.6%) added the AI-investment angle. Rounding out the list were cyclicals and financials — chemicals, tires, precision components and megabank Mizuho (+4.5%). Most names moved on the sector theme rather than standalone company news.

Common Themes
The decliners were mild — none fell more than 3% on a strongly up day — and look like rotation rather than distress. High-valuation electronic-component makers Murata (-2.9%) and Kyocera (-1.1%) gave back ground as money moved into cyclicals; defensive and domestic-demand names (frozen-food maker Nichirei, e-commerce platform ZOZO, medical-info group M3, internet firm LY Corporation) were sold in the risk-on rotation. None of the ten had a clear negative catalyst on the day; the moves read as profit-taking and sector rotation into the AI-infrastructure and financials leaders.
Overall read
Money rotated into the AI-infrastructure supply chain — silicon wafers, semiconductor materials and data-center cabling — and into megabanks, and out of defensive, domestic-demand and high-valuation component names. Cyclicals and financials, not just megacap tech, did the heavy lifting on the day.
