up close their relative performance is similar but over a longer time period they are diverging?


that last big spike up with fmg above rio pct wise was jul 2160 to june 2017 since then fmg has been doing those smaller price oscillations downwards and rio was quite good until june this year where both rio and fmg have performed almost identically in a pct wise share price performance based manner wrt their respective inital stock prices since that moment even though rio are building a huge copper mine in mongolia and have a few other non iron asets as well not just iron.

if the selling 8s based on iron price forevasts i would expect rio to not go down as much as fmg because they are more diversified but they gone down basically the same lately from what i can see so its just mining in general
