I think, paschi is right, PRB is all about Borden at this point in time and although we got news there, they were less favourable than expected.
Hence the share price decline on small volume.
Where will this stop ? I don´t know.
But without any further and better news from Borden, I can´t see a big increase either.
FANTOMAS
P.S.: Maybe Cliffs decides to buy BC. That surely would help.
