I believe BMO is lurking in the shadows today but taking the lead so far as the primary seller is TD. BMO bought a piece a few days ago below .50. There is probably one or more hedge funds using various brokers continuing to pressure the shares. TD has been on the lead for the past three days or so. Research Capitol could be working a sizable buy order currently as they have just surfaced buying a couple of 10m or more share lots at .60 and .61.
Hopefully, this will all just be insignificant blabber once PRB asserts itself through the next few day's 10 day resistance in the .63 to .65 area.
