An interesting article in Seeking Alpha :
https://seekingalpha.com/article/4615554-betting-on-america-with-mp-materialsWith the MP stock at US$24.30, and LYCSF at US$4.72 could a large part of the difference be due to State Street (to a limited extent?) and the Malaysia handicap? The article does mention MPs location in ultra woke California as a risk factor.
Or could it be that LYC needs to raise its profile in the US?
Note that Australian BHP - also a duel ASX/NYSE stock - is equivalent of US$28.69 on the ASX and $57.80 on the NYSE.
