Last year, oil stocks were very hot. But the chart of OIH does not look like that of Chinese stocks (A-shares): up,up,up,up,....up. Within 1 year, OIH can have 25-30% swing, though it trended up. Similarly, FCX has been sold to $50 in January 2007.

Copper is hot, but it does not mean we can chase high. You may have a look at FCX. ( I don't trade Canadian/Toronto markets). FCX follows the copper futures.
