Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you expect the natural gas industry to prosper over time as the rising cost of oil makes gas more favorable, the First Trust ISE-Revere Natural Gas Index ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The gas ETF's expense ratio -- its annual fee -- is 0.60%. That's a bit higher than many ETFs, but also considerably lower than most mutual funds.
This ETF doesn't sport the most impressive performance over its relatively short life. On average, it has underperformed the S&P 500 over the past three 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.
What's in it?
Many natural-gas-related companies didn't turn in pretty results over the past year -- partly due to low prices for natural gas. Still, they may well see their fortunes change in the coming years.
The big picture
A well-chosen ETF can grant you instant diversification across any industry or group of companies -- and make investing in and profiting from it that much easier.
