Capitalize on the AI infrastructure supercycle with our selection of the 34 best 'picks and shovels' of the AI gold rush converting record-breaking demand into massive cash flow. ## What Is Fujikura's Investment Narrative? To own Fujikura today, you have to believe that its pivot toward AI-oriented optical connectivity can justify a premium valuation and very large past share price gains. The new plan to invest up to ¥300,000,000,000 to roughly triple optical fiber and SWR®/WTC® capacity in Japan and the US, alongside its role in US Conec’s expanded-beam MMC ecosystem, reinforces AI data centers as the core near-term catalyst. It also raises the stakes: execution risk on a multi-year capex cycle, potential demand swings, and already elevated earnings expectations matter more now than they did before this announcement. With forecasts already upgraded and no change to near-term guidance, the news feels more like a longer-term capacity story than an immediate earnings shock, but it could reshape how investors think about both upside and downside. However, there is one capacity-related risk here that investors should really understand. Fujikura's shares are on the way up, but could they be overextended?
