Nintendo jumps 6.8% as Japanese investors rotate out of AI

Nintendo rose as much as 6.8% in Tokyo for a third straight day, its longest winning streak since mid-March. Bandai Namco and Konami each gained more than 9% in the same session. The move reflects a broader rotation by Japanese investors over two weeks, shifting from AI-aligned components of the TOPIX into established intellectual-property and consumer franchises. These franchises’ earnings are less dependent on the capex cycle currently supporting US semiconductor and hyperscaler stocks. The rotation also coincides with a technical bounce after Nintendo’s earlier May decline tied to full-year guidance and a Switch 2 price-hike reaction. AI fatigue in Japan is linked to underperformance among AI capex names as valuation concerns rise.

"Nintendo's stock climbed as much as 6.8% in Tokyo on Tuesday for its third straight day of gains, Bloomberg reported , in the company's longest winning streak since mid-March. Bandai Namco Holdings and Konami Group each rose more than 9% on the same session."

"The session was the visible expression of a broader rotation Japanese investors have been signalling for two weeks: out of the AI-aligned components of the TOPIX, into established intellectual-property and consumer franchises whose earnings do not depend on the capex cycle currently lifting US semiconductor and hyperscaler stocks."

"The setup for the rotation is the part to read carefully. Nintendo's stock had fallen close to 10% earlier in May after the company's full-year guidance disappointed against consensus and its Switch 2 price-hike announcement landed badly."

"Japanese investors had spent most of Q1 and early Q2 of 2026 piling into the names attached to the AI capex cycle: SoftBank, Tokyo Electron, Disco, Advantest, and Renesas. Those names have, on the past three weeks of TOPIX trading, started to underperform against valuation backdrops that the Japanese institutional buyer base is now treating as stretched."
