Nikkei 225 — daily market movers
Macro backdrop
The Nikkei 225 rose 1.39%, rebounding from the prior session's roughly 5% slide — its worst day since March — which had been driven by fears over the sustainability of AI spending (CoreWeave's debt) and a six-session slide concentrated in heavily weighted chip names. Friday's bounce was led by a retreat in US Treasury yields and more dovish Fed commentary, while Nvidia CEO Jensen Huang's reassurance on CoreWeave's finances eased AI-financing concerns and let semiconductor and high-beta names recover. It was a textbook risk-on rotation, with money moving out of defensives back into cyclicals.

Common Themes
Two distinct engines drove the gainers. First, two large idiosyncratic earnings winners — BayCurrent (+17%) and SHIFT (+17%) — both on consulting/software results that beat estimates and had nothing to do with the macro. Second, and more thematic, a tight cluster of heavy-industry and defense names — Kawasaki Heavy, Mitsubishi Heavy, IHI and Japan Steel Works — all up 5-6%, rebounding hard as risk appetite returned and riding the government's sustained defense-spending push. Semiconductor-related names (Ibiden, Lasertec) also bounced as the chip complex recovered from Thursday's rout.

Common Themes
The losers were strikingly uniform and mild — the worst decliner fell only 2.3% on a day the index rose 1.4%. Nearly every one is a low-beta defensive or domestic-demand name: utilities (Kansai Electric, Osaka Gas), domestic retailers (MUJI, Takashimaya, Fast Retailing), logistics (Yamato) and entertainment (Toho). This is textbook risk-on rotation — money leaving defensives to chase the rebound in cyclicals, semiconductors and heavy industry. None of the losers had company-specific bad news; Fujikura's small dip looks like simple profit-taking after a strong run rather than part of the defensive theme.
Overall read
The session was a sharp relief rebound from Thursday's -4.9% AI-driven plunge, powered by falling US yields and easing fears over AI financing after Nvidia reassured on CoreWeave. Money rotated decisively out of defensives and domestic-demand names into cyclicals, semiconductors and especially heavy-industry/defense, while two earnings beats (BayCurrent, SHIFT) delivered the day's biggest individual pops. The muted size of the declines shows this was rotation, not broad selling.
