Core Scientific is trading 4.05% up at $16.69 after rebounding from the September 15 close of $16.04 following a sharp prior-session decline; no clear company-specific announcement explaining the September 16 move was identified. - Recent searches found mostly price and historical-news listings. - Bitcoin is down 0.40% and Ethereum down 0.51% since their previous closes, so crypto weakness does not explain the gain. - The modestly positive broader market may be contributing, but evidence remains limited.
