This ETF doesn't have much of a track record yet, as it's not even a year old. Year-to-date, it's underperforming the S&P 500, but such a short time frame is close to meaningless. As with most investments, we can't expect outstanding performances in every quarter or year. Investors with conviction need to wait for their holdings to deliver.
What's in it?
Several of this ETF's component stocks have likely made strong contributions to its performance. PotashCorp

The big picture
Demand for natural resources and commodities isn't going away anytime soon. A well-chosen ETF can grant you instant diversification across these companies -- and make investing in and profiting from the sectors that much easier.
