Hey JJ,
Leaving aside the cyclical nature of the Copper industry, Lundin is one of the better ones in the industry. My personal preference is Turquoise Hill, but Lundin is a good company. It is trading at a premium to its peers, but that premium is likely warranted as the second largest copper play on the TSX Index. Even at a premium however, its not exactly expensive here. It is trading at only 9.2 times earnings, 8.1 on a forward basis. I say this but the entire industry is similarly cheap.
The company dropped recently on weaker than anticipated Q3 results and it received a few downgrades. It missed on lower copper prices and lower sales. The good news is that it is still generating strong cash flows. It was having issues at Candelaria but it seems the major maintenance there is now complete. It also re-iterated full year guidance despite Q3.
OVerall, i'd be comfortable with LUN here with the caveat that it'll all depend on where copper prices go.
