NBIS is trading at 3.17% down now at $109.84 after a sharp multi-day selloff that follows months of extraordinary gains and a recent hedge fund investment. While Nebius Group (NBIS) stock had surged 390% in 2025 and recently attracted attention from a $286K RFG Advisory hedge fund investment, today's decline comes amid cooling enthusiasm for AI infrastructure stocks and profit-taking after a parabolic run[1][2][3]. There are no new company-specific negative headlines today, but broader market optimism has not lifted NBIS, suggesting sector rotation or valuation concerns are weighing on shares despite the overall market trading higher[3].
