The recent price declines of Nvidia's (NVDA) B200 AI chips, spurred by rapidly increasing competition in the AI-chip space, bode poorly for Nebius' (NBIS) outlook. Meanwhile, over the longer term, the firm could be hurt by the advent of space-based data centers, while the stock's valuation continues to be extremely high.
In light of these points, I suggest that investors consider selling Nebius' shares.
