Embraer is trading at $75.05, up 4.08%, in line with defense-sector strength. - No clear company-specific announcement explaining the October 29 move surfaced in the search; Embraer’s record-backlog report predates the session. - The defense sector is up 2.15% amid heightened Iran-related tensions; reports also describe Iran’s claim of downing a U.S. drone. - Major U.S. indexes are lower, so broad-market strength does not explain the gain.
