Fermi is trading at $2.90, up 10.88%, as the reason for the sharp rise remains uncertain. - No clear company-specific catalyst was identified for the October 28 gain; available reporting described the earlier move as lacking a clear explanation. - AI-related strength followed the prior session’s rally, but reporting presented it only as background, not a confirmed cause. - Broader markets were mixed, and the supplied biotech-sector rally does not clearly explain Fermi’s move.
