Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you expect the insurance industry to thrive as our population grows and more people need more protection, the SPDR KBW Insurance ETF
ETFs often sport lower expense ratios than their mutual fund cousins. The insurance ETF's expense ratio -- its annual fee -- is a relatively low 0.35%.
This ETF has not performed very impressively, lagging the S&P considerably over the past five years. 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. Low interest rates have held many insurers back, while property insurers have taken hits when disasters such as Hurricane Irene have struck, as investors get skittish about blows to insurers' earnings. Still, strong insurers plan for occasional disasters, and many of this ETF's holdings seem attractive, sporting P/E ratios below 10.
With a low turnover rate of 9%, this fund isn't frantically and frequently rejiggering its holdings, as many funds do.
