Ero Copper is trading 4.28% up at $37.52, with firmer copper prices, renewed Chinese buying after the holiday, and supply concerns following a strike at Chile’s Centinela mine supporting the move.

  • No clear company-specific announcement explaining the October 9 move surfaced in the available results.
  • Major U.S. indices were up only modestly, making sector and copper-market sentiment more relevant than a broad-market rally.
