Capstone Copper Shares Plunge on Copper Price Drop

Capstone Copper's shares have taken a hit, falling 8.89% to A$14.96 on the ASX as the company's copper prices slipped 2.2% overnight.

The move comes amidst a broader market sell-off, with the ASX 200 Materials index down 3.08% and government bond yields at historic highs.

Capstone Copper's high beta of 2.6 means its shares tend to amplify market sentiment swings, making it vulnerable to downturns in commodity prices and interest rates.

The company's guidance for 2026 production has been a point of contention, with some investors skeptical about the promised cost savings.
