description: "Nano Nuclear fell -14%, CGN Mining fell -12%. The uranium mining and nuclear power sector collectively crashed today, dropping a significant amount. Lightbridge also fell over nine percentage points, while the uranium ETF and Cameco both fell around five percentage points. Even the leading stocks didn't hold up.This group had previously surged on narratives around AI power consumption and small reactor policies, with valuations becoming severely overstretched. Today's move looks more like a combination of profit-taking at high levels and a contraction in risk appetite. The long-term logic for uranium prices hasn't broken, but stocks driven purely by policy expectations and milestones experience particularly deep pullbacks when catalysts are lacking. Cameco's relative resilience also shows that capital still values fundamentals."
