I see nobody has stepped up to the plate with any opinions, so here's mine: (assuming K's gold originated from neutron stars LOL):
K should come through with decent earnings as I believe they have a relatively high % of gold and silver production from their active mines compared to copper and zinc which have suffered the largest commodity price decline over the last 6 months or so.
I would expect the K sp should do well right into Feb 18 (subject to any wild swings in Gold prices) and I would expect that the sp will drop after that (unless they report outstanding numbers) just because of the "sell on news" mentality.
That's my $0.02.
