Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you expect the world's developing economies to keep developing, and at a faster clip than our developed economy, the Vanguard MSCI Emerging Markets ETF
The basics
ETFs often sport lower expense ratios than their mutual fund cousins. The emerging markets ETF's expense ratio -- its annual fee -- is a very low 0.22%.
This ETF has performed rather well, outperforming broader international benchmarks handily over the past three and five 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 a low turnover rate of 12%, this fund isn't frantically and frequently rejiggering its holdings, as many funds do.
What's in it?
Several of this ETF's components made strong contributions to its performance over the past year. Sasol
Other companies didn't add as much to the ETF's returns last year but could have an effect in the years to come. Brazilian oil company Petrobras
The big picture
Emerging markets are likely to keep emerging for a long time. A well-chosen ETF can grant you instant diversification across the industry -- and make investing in and profiting from the sector that much easier.
