Why is Nebius stock sliding today?

Nebius Group's stock is down 4.7% in pre-market trading, retreating from a recent rebound. The decline is attributed to broader caution in the AI infrastructure sector, including investor resistance to Nscale's IPO valuation and feasibility concerns about U.S. AI data center projects. Analysts had previously upgraded sector peers, but the stock is now under pressure from high short interest and unfavorable technical indicators.
