Nebius Group N.V. (NASDAQ:NBIS) shares surged 7.46% to $89.95 on January 2, 2026, marking a strong rebound after closing down 1.72% on December 31. This positive movement, reported by MarketBeat, occurred despite U.S. filings on December 31, 2025, revealing several insiders planned "sell-to-cover" transactions for January 2, as detailed by ts2.tech. The significant price increase suggests the market successfully absorbed the potential selling pressure from these planned sales.
