On September 23, Southern Copper Corp fell 3.36% in regular trading, trading at $199.40 per share, with turnover of $6.073 million. The stock reversed sharply from earlier session gains, reflecting broad weakness across the copper mining sector.

On the news front, the copper sector came under renewed pressure as uncertainty surrounding the US Section 232 tariff policy on refined copper continued to weigh on sentiment. According to a recent Q4 copper market outlook, the US 232 copper tariff has become the core variable for the market heading into Q4 and beyond. The report outlines scenarios ranging from strict enforcement — with a 15% tariff on refined copper potentially taking effect in early January — to a prolonged period of indecision that could sustain market volatility. Earlier reports noted that the White House had not yet reached a decision on refined copper tariffs, a headline that previously triggered sharp pre-market declines across copper stocks.

Within the Copper sector, Freeport-McMoRan fell 3.25%, Ero Copper fell 3.51%, TREKOR METALS fell 4.06%, while Idaho Copper Corporation rose 3.54%.
