Carrefour is trading 4.45% up at $102.57; the reason for the quoted move remains unclear. - The last session ended October 30, 2026; the market was closed on November 1, so this is not a confirmed November 1 session move. - No company-specific announcement explaining the increase surfaced in the search. - The latest identified company catalyst was the October 20 outlook reduction tied to unrest in France; broader-market indicators do not establish a matching explanation.
