Hi Mike,
The abbreviated answer is perhaps.....but do you want to make money, feel good, or both?
Personally, I think some commodities may be on the verge of a correction. The trouble with an ETF is that you're buying a basket....and not everything in the basket may be what you may want to take home for an extended period.
Also, this is the politics board. This means that the main purpose of this forum is to whine and bleat about those whom we don't care for with very little empirical evidence to back up our statements.
Perhaps you would get more feedback if you would direct your question to the ETF board.

Best of luck Mike.
