Our goal in this profile is to help investors wade through the many competing ETF offerings available. Using our long experience as an ETF publication, and nearly 40 years in the investment business, we can help select those ETFs that matter and may or may not be repetitive. The result is a more manageable list of issues from which to view and make selections.

With inflation pressures waxing and waning many believe it's important to have portfolio exposure to a basket of commodity ETFs. Why? Because commodity markets often feature noncorrelated performance with conventional portfolios. Further, given easy money policies which began in 2008 has hurt the value of the dollar. Since most commodities are priced in dollars this puts upward pressure on prices which can become inflationary. We've cobbled some good choices of commodity tracking ETFs and ETNs where repetitive choices may exist but leave it to investors to pick the ones that suit them best. 

As a former CTA (Commodity Trading Advisor) and CPO (Commodity Pool Operator) I know the value of having an allocation of most portfolios to the commodity sector. These provide increased diversification opportunities for any portfolio. And, in nearly 40 years of seeing these positive effects during a variety of market conditions, I know first-hand their benefits. 

We're not ranking these 10 ETFs favoring one over another so don't let the listing order mislead you. Although we may use some of these in ETF Digest portfolios it's not our intention to recommend one over another.

Whereas our previous technical analysis methodology involved using evaluating monthly charts commodity markets must be viewed with shorter time horizons. This is due to obvious increased volatility but also due to the peculiar nature with which underlying commodity contracts trade. Some contracts expire monthly and others quarterly. Some have serious seasonal characteristics inherent with agricultural issues such as growing seasons, weather and disease. Therefore, it pays to be active and utilize a combination of weekly and daily charts to manage risk.

Four risk factors should be considered:

'         The CFTC's varying considerations regarding commodity position limits as applied to the assets of ETF and ETNs--still in limbo.

'         The credit quality of ETNs given these are "notes" many guaranteed by Barclay's and Deutsche Bank.

'         Backwardation (back month contracts lower than front month) and Contango (back months higher than front month) can negatively affect contract rollover for investors.  

'         Since most commodities trade in dollars, the value of the dollar can positively or negatively affect performance.

ProShares and Deutsche Bank features inverse and leveraged long ETFs/ETNs for those investors wishing to hedge or speculate.
