Jiangxi Copper's stock plummeted 5.08% during intraday trading on Friday, extending a multi-session pullback in the copper sector.

The decline follows profit-taking that intensified after the stock's strong rally earlier in the week, when it surged over 5% and 3% on consecutive days. Market analysts describe the movement as a technical correction driven by "fear of heights" rather than a fundamental reversal, as short-term gains had become stretched.

The broader copper sector faced similar selling pressure, with peers including China Daye Non-Ferrous Metals, Jinxun Resource, and China Non-Ferrous Mining also declining. Despite the pullback, copper's macro backdrop remains supportive with supply constraints, including Freeport's delayed Indonesia project restart and lowered global output guidance.
