I can only assume CUZ, CSK, FTHave been targeted for termination by short sellers, as each have been destroyed by huge volume sellers who seemingly don't care what price they get.
Look at CPO, CSR, ECS ... relatively untouched.
That's my theory anyway; we were due for a correction in the ECS range, but with Cobalt prices good I can't explain the ongoing massacre especially in CUZ/CSK.
