Discussion
Cobalto: precios bajos y volatilidad
Hoy por hoy, existe un contexto que preocupa a los productores de Cobalto en el mundo y a todo el sector minero.
En lugar de subir sus precios, el Cobalto ha caído un 30% desde el comienzo de 2019, lo que hace que los precios de las acciones de las compañías inviertan fuertemente en su extracción a la baja.
Las acciones de Cobalt 27, por ejemplo, cayeron en valor en más del 65% entre junio de 2018 y el 15 de febrero de 2019, lo cual tensiona y pone en alerta al mercado.
