Some misconceptions -BNK does not receive 59% of Brent - last figure I saw was 66%
Crude has dropped about 12% during which time the US dollar has appreciated about 4% against the loonie meaning companies like BNK receive about 8% less not 12% less in real terms. Obviously negative but not nearly as negative as the doom sayers would have you believe
BNK - (apparently forecast to drop by some crystal ball types) - is simply dropping on the same tide that most juniors and the wider market are dropping on - not as bad as some not quite so good as others - pretty much a middle of the road performance
As a previous poster correctly pointed out (leftiemike I think it was) - BNK was doing fine with $80 oil not so long ago and with a higher SP than today.
Time to take a deep breath - stop panicking, and step in and buy in increments if funds allow.
Thats what I will be doing once the dust settles.
