Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you're intrigued by volatile, high-beta stocks that often perform well in booming markets and you expect the stock market to grow briskly in the coming years, the PowerShares S&P 500 High Beta ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The PowerShares ETF's expense ratio -- its annual fee -- is a very low 0.25%. The fund is rather small, too, so if you're thinking of buying, beware of occasionally large spreads between its bid and ask prices. Consider using a limit order if you want to buy in.
This ETF doesn't have much of a performance to assess, as it's extremely young. Year-to-date, it's ahead of the S&P 500, but 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.
