On June 8, Southern Copper rose 3.41% in pre-market trading, trading at $178.5/share, with trading volume of $988,000, as the copper sector collectively strengthened.

On the news front, global copper mine supply-side disruptions continue to intensify. Peru issued an emergency decree due to an energy crisis, with major copper mines reducing capacity by approximately 20,000 tons per month due to power rationing. Additionally, full resumption of Indonesia's Grasberg mine has been delayed to early 2028, expected to result in over 100,000 tons of reduced copper supply. Institutions noted that the tight supply-demand imbalance remains unchanged.

Southern Copper had previously rallied above $198 supported by Peru's energy crisis and global copper supply disruptions, but short-term pressure from surging U.S. COMEX inventories caused the stock to rapidly retrace from those levels. The current pre-market rebound appears to be a technical recovery driven by improving sector sentiment. Within the Copper sector, Freeport-McMoRan rose 2.41%, Ero Copper rose 3.74%, and Taseko Mines rose 4.81%.
