Nintendo rises 6.8% as Japanese investors shift away from AI.

      On Tuesday, Nintendo's stock surged by as much as 6.8% in Tokyo, marking its longest winning streak since mid-March, as reported by Bloomberg. Bandai Namco Holdings and Konami Group also saw increases of over 9% during the same session. This trading session reflected a broader shift that Japanese investors have been indicating for two weeks: moving away from AI-related components of the TOPIX and into established intellectual property and consumer franchises that aren't reliant on the current capex cycle boosting US semiconductor and hyperscaler stocks.

      The catalyst for this rotation is critical to understand. Earlier in May, Nintendo's stock had dropped nearly 10% after the company's disappointing full-year guidance and a poorly received announcement regarding the Switch 2 price increase. The recent movements can be seen as two overlapping narratives: a technical rebound from undervalued levels and a shift in sector allocation that's seized this specific upturn.

      Bloomberg characterizes this rotation as stemming from ‘AI fatigue’ with a particular interpretation in the local context. Throughout most of Q1 and early Q2 of 2026, Japanese investors were heavily investing in companies tied to the AI capex cycle: SoftBank, Tokyo Electron, Disco, Advantest, and Renesas. However, these companies have underperformed in the last three weeks of TOPIX trading against valuations perceived as stretched by Japanese institutional investors.

      The announcement of the $25 billion joint venture between Google and Blackstone did not disrupt this trend; it merely adds to the data points indicating the shift is underway. Every new AI capex commitment heightens the significance of the fundamental terminal-value questions, and the past two weeks of order flow suggest that the Japanese institutional market is growing uneasy with the responses.

      This macro context exists within a larger conversation about AI valuations that has unfolded over the last two months on both sides of the Pacific. Global CAPE multiples have reached levels not seen since 2000, sector concentration in US large caps has surpassed 2000 dot-com levels, and earnings concentration within the AI category has hit all-time highs.

      Proponents argue that companies in the AI cohort are profitable in ways that the 2000 cohort was not. However, skeptics contend that the capex profile of the AI cohort is unprecedented, that the disparity between announced capex and earnings is widening, and that the current rotation in Japanese equities serves as a leading indicator, not a contrarian one.

      What characterizes the Nintendo trade is its focus on intellectual property and franchises. Despite the disappointing guidance in Q1, the Switch 2 platform, set to launch in late 2024, presents an installed-base trajectory that suggests a multi-year earnings potential extending into the next decade. Bandai Namco and Konami also enjoy similar optionality. None of these companies is expected to be part of the $700 billion+ AI capex cycle anticipated for 2026, and recent evidence indicates that Japanese institutional investors are becoming more at ease with this reality.

      The technical aspect of this scenario is the second factor. The surge on Tuesday coincided with a broader pattern of three consecutive days of gains in consumer-oriented Japanese stocks, which Bloomberg describes as a ‘hunt for bargains’ within the TOPIX. The combination of low entry prices, appealing intellectual property prospects, and underperformance of AI-related stocks typically fuels a multi-week rotation rather than a fleeting upturn.

      The sustainability of this trend will depend on the forthcoming AI cohort earnings results and their implications for the convergence of capex and earnings. The unresolved factor is the upcoming Q2 earnings disclosures from the AI cohort. Microsoft, Alphabet, Meta, and Amazon are set to report between July and August on whether their capex investments are translating into accelerated cloud and AI revenues at the rates currently reflected in multiples.

      The rotation in Japanese gaming stocks represents a cautious hedge against the possibility that the answer to these questions could be negative. Nintendo's performance on Tuesday shouldn't be viewed as a contrarian win; rather, it’s a notable movement that has garnered attention.
