You have a good point on the oil price, but this point seems limited to the US. Europe and China are dependent on foreign fossil fuels and this is part of the reason they're pushing ahead with EV's on such a large scale. I believe EV's will happen in China and Europe regardless of what the oil price is doing.
As for Magnis, their new multi-year low seems to be an indication of what the market thinks about their future, and current MC. It is still $160m with only $8.5m of that backed by cash (last quarter).
The 3 year downtrend looks set to continue.
