ETFs often sport lower expense ratios than their mutual fund cousins. The energy ETF's expense ratio -- its annual fee -- is a very low 0.18%.
This ETF has performed very well, handily beating the world markets over the past three, five, and 10 years. As with most investments, of course, we can't expect outstanding performances in every quarter or year. Investors with conviction need to wait for their holdings to deliver.
With an ultra-low turnover rate of 3%, this fund isn't frantically and frequently rejiggering its holdings, as many funds do.
What's in it?
