Exchange-traded funds are similar to index funds that trade like a single stock. Until the advent of the ETF, it was impossible to trade indexes this easily through an equity account. Most ETFs are relatively static in make-up, like the SPY or QQQQ index funds. Others, like some of the PowerShares funds, are dynamic and the holdings are changed routinely. ETFs have risks similar to stocks in that their value can rise or fall at the discretion of the marketplace. Some ETFs, like international funds and narrowly based indexes, have special risks that the investor should be aware of. However, used properly ETFs can provide an efficient and effective investment vehicle for achieving results that were near impossible for the typical investor to achieve prior to their development.
