Since Tuesday's US market open, January 26, Freeport-McMoRan's stocks have been depreciating actively. At the time of publication the stocks have already lost 9.06%.
It is likely that the decline occurred as the US top mining company trimmed 2021 production guidance.
However, note that the company posted the fourth-quarter earnings data, which was better-than-expected. Also, the copper and gold miner's profit was in line with the expectations.
