Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you'd like to add growing small-cap stocks to your portfolio because of their ability to grow rapidly, the iShares S&P Small Cap 600 Growth ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The small-cap ETF's expense ratio -- its annual fee -- is a relatively low 0.25%.
This ETF has a strong performance record, beating the S&P 500 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.
