BHP Group is trading at $78.19, down 3.25% in pre-market on October 22, 2026, with the move aligning most clearly with sector-wide metals weakness. - Copper prices fell to five-week lows, weighing on mining shares; an October 22 report linked the pressure to BHP Group’s decline. The Australian market also softened amid AI uncertainty and interest-rate worries. - September-quarter copper production was 400,700 tonnes, down 19% year over year; FY2027 guidance remained unchanged. The information does not establish the quarterly update as the direct cause of the pre-market drop.
