I would not sell right now.
I think someone has knowledge that nickel price has hit bottom, and is going to shot up.
From last Sept. price has slid from 21.50 to 17.00 then rose back to 21.70 in Feb, it then slid to a record low of 15.00 in mid Aug. and has since rose quite sharply.
With the big slide in last 6 month MCR still made a profit.
IMO. MCR is the best company to benefit from a nickel price rise,
